【期刊论文】A new anhydrous proton conducting material based on phosphoric acid doped polyimide

A new anhydrous proton conducting material based on polyimide and phosphoric acid composite was prepared. The interaction between polyimide (PI) and phosphoric acid was investigated by FTIR. The results show that phosphoric acid interacts with polyimides mainly by hydrogen bonds rather than by protonation of PI at room temperature. Environmental scanning electron microscopy (ESEM) was employed to study the surface morphology of the membranes. The results show that the surface of PI-xH3PO4 membranes is very compact and homogeneous. Proton conductivity and methanol permeability of PI doped with phosphoric acid (PI-xH3PO4) were also studied. Proton conductivity of PI-xH3PO4 membranes increases with increasing concentration of phosphoric acid. Hydrogen bond seems to play an important role in the proton conductivity of this system. Effects of osmotic on the direct diffusion process of methanol in the membranes can be negligible due to the absence of micro-pore structure as already shown in ESEM results. Effects of methanol concentration and temperature on the methanol permeability of PI-xH3PO4 membranes were also discussed. Methanol permeability in PI-xH3PO4 membranes decreases with increasing methanol concentration, and increases with increasing temperature.

Magnetorheological (MR) fluids based on glycol, iron powder, polyvinylpyrrolidone (PVP), and carbon nanotubes (CNTs) were prepared. Effects of polyvinylpyrrolidone and carbon nanotubes on sedimentation stability and magnetorheological properties were studied. It is found that the synergetic effects of PVP and CNTs improve the sedimentation stability significantly, and the addition of CNTs reduces the sedimentation velocity and increases the equilibrium sedimentation ratio of the magnetizable particles in MR fluids remarkably. The addition of PVP can reduce the sedimentation velocity of the magnetizable particles, but cannot increase the equilibrium sedimentation ratio and will not change the up trend of apparent viscosity with the increasing intensity of the external magnetic field. When the PVP content is lower, the increment of original apparent viscosity of the MR fluids at zero-intensity of magnetic field is inconspicuous, and their values of apparent viscosity under magnetic field are similar. However, the apparent viscosity of the MR fluids increases tremendously when the contents of PVP increase to certain degree. The results show that the synergetic effects of PVP and CNTs not only improve the sedimentation stability of the MR fluid but also promote its magnetorheological effect.

High-pressure electrical conductivity studies have been carried out with poly (p-phenylene)s with oxyethylene side-chains (PPPŽEOx/y), which were blended with LiCF3SO3. Measurements were performed at pressures up to 280 MPa and at different temperatures. The influences of salt concentration, side-chain length, temperature, and plasticizer content on the relative conductance and activation volume are investigated. The temperature-dependent conductivity of the sample is non-Arrhenius and exhibits Williams-Landel-Ferry (WLF) behavior. The logarithm of relative conductance for PPP (EO)x/yrLiCF3SO3 decreases almost linearly with increasing pressure but increases with salt concentration and side-chain length. As temperature increases, the activation volume becomes smaller but remains positive for PPP (EO) rLiCF SO. At higher salt concentrations and longer side-chain lengths, a smaller activation volume for the ion xr y 3 3 motion is found. These results can be interpreted such that PPP (EO) rLiCF SO behaves like a true polymer electrolyte xr y 3 3 where ion transport is mediated by segmental motions of the EO side-chains. The addition of tetraethylene glycol dimethyl ether (TEGDME)as a plasticizer increases the activation volume but reduces the conductance.

Abstract: The preparation of sulfonated polybenzimidazole (sPBI) by the grafting of (4-bromomethyl) benzenesulfonate onto polybenzimidazole (PBI) has been investigated. The methanol permeability and proton conductivity of PBI and sPBI have been studied, and the effects of methanol concentration and temperature on the methanol permeability of PBI and sPBI membranes are discussed. The results showed that the PBI membrane is a good methanol barrier. Methanol permeability in this membrane decreases with increasing methanol concentration and increases with increasing temperature. The temperaturedependence of methanol permeability of PBI and sPBI membranes is of the 'Arrhenius type'. Methanol permeation of sPBI is less sensitive to temperature than that of PBI. However, sPBI is a poorer methanol barrier when compared to PBI. Methanol permeability in sPBI membranes increases with increasing methanol concentration and temperature. The proton conductivity of sPBI is 4.69×10−4 Scm−1 at room temperature in the hydrated state. The DC conductivity of sPBI–H3PO4 increases with increasing temperature. Proton transport in sPBI-H3PO4 is less sensitive to temperature than that in PBI-H3PO4.

In the present work, poly (N-methylbenzimidazole) (PNMBI) and poly (N-ethylbenzimidazole) (PNEBI) were synthesized by methylation and ethylation of polybenzimidazole (PBI). Methanol permeability of PNMBI, PNEBI, and PBIwas studied. Effects of methanol concentration and temperature on methanol permeability of PNMBI, PNEBI, and PBI membranes are discussed. The results show that PBI, PNMBI and PNEBI membranes are good methanol barrier. Methanol permeability in PBI, PNMBI and PNEBI membranes decrease with increasing methanol concentration. Temperature dependence of methanol permeability of PBI membrane can be fitted by Arrhenius equation. Proton conducting materials based on N-substituted PBI were prepared by successive immersion of the membranes in phosphoric acid solution. Interaction between PNMBI and phosphoric acid was studied by FTIR. It is indicated that the interaction in PNMBI/xH3PO4 and PBI/xH3PO4 is mainly due to the protonation. Proton conductivity of phosphoric acid-doped PNMBI and PBIwas investigated by impedance measurements. Proton conductivity of acid-doped PNMBI increases with the increasing doping level and temperature. Proton conductivity of phosphoric acid-doped PNMBI and PBI is governed by a hopping mechanism rather than a mechanism mediated by the segmental motions in the polymer.

Covalently bonded WO3/polyvinylimidazole (C-WO3/PVI) core-shell microspheres in sizes of 250 nm were prepared. The microstructures of C-WO3/PVI core-shell microspheres were characterized by TEM, IR, and XRD. It is found that the chemical and thermal stabilities of CWO3/PVI core-shell microspheres are higher than those of pure WO3 nanoparticles and noncovalently bonded WO3/polyvinylimidazole (NCWO3/ PVI) core-shell microspheres. This is attributed to the strengthened interaction of the WO3 nanoparticle core and the PVI shell resulting from the interaction of covalent bonds. The electrochromic device made by the C-WO3/PVI core-shell microspheres was studied. It is suggested that the C-WO3/PVI core-shell microspheres exhibit better electrochromic properties than pure WO3 nanoparticles or NC-WO3/PVI core-shell microspheres.

21T, and the coercive force (Hc) of the soft magnetic composite particles is 8.03kAm−1. The apparent density of the hollow magnetizable particles is around 1.5gml−1, which is only one-fifth or one-fourth of that of normal soft magnetic particles based on pure Fe or Fe3O4 powder. The MR fluids based on such kind of soft magnetic composite particles show promoted sedimentation stability and magnetorheological properties, which are attributed to the novel hollow structures.

【期刊论文】Preparation and proton conductivity of acid-doped poly(5-vinyltetrazole-co-acrylonitrile)
浦鸿汀, Hong-ting Pu*, Sheng Ye

Poly(5-vinyltetrazole-co-acrylonitrile) (P(VT-co-AN)) with different molecular weight and tetrazole content was synthesized from polyacrylonitrile. The chemical structures of the copolymers were characterized by FT-IR, H NMR spectroscopy and elemental analysis. The surface structure of the copolymer was characterized by scanning electron microscopy (SEM). Membranes of these polymers were prepared and the effect of molecular weight, tetrazole content, and acid doping level on the proton conductivity of phosphoric acid doped P (VT-co-AN) membranes was studied. The membranes with lower molecular weight, higher tetrazole content, or higher acid doping level show the higher proton conductivity. The temperature dependence of the proton conductivity of the acid doped membranes can be fitted by a simple Arrhenius equation either below or above the glass transition temperature of the copolymer. P(VT-co-AN) (Mn=80,000)/1.0H3PO4 can exhibit an anhydrous proton conductivity of 10 4 S cm 1 at room temperature and the proton conductivity increases with increasing temperature and acid doping level.

An ethyl-vinyl acetate copolymer (EVA) preirradiation-grafted with N-isopropylacrylamide (NIPAAm) was prepared. Various methods which can be used to control the grafting reaction are described. DSC and TMA were employed to characterize the surface thermosensitivity of the graft copolymer. It is indicated that the surface of EVA grafted with NIPAAm shows thermosensitivity similar to a partially crosslinked poly-NIPAAm (PNIPAAm) gel. The response to the change of temperature through the lower critical solution temperature (LCST) of the graft was swifter than that of the PNIPAAm gel. SEM revealed a micropore structure in the surface layer of the sample. DSC was also used to analyze the water state in the surface layer of the sample.
