Preparation of Polypropylene/Carbon Nanotube Composite Powder with a Solid-State Mechanochemical Pulverization Process
Journal of Applied Polymer Science, Vol. 93, 378-386 (2004),-0001,():
A solid-state mechanochemical pulverization process, that is, pan milling, was used to prepare a polypropylene (PP)/carbon nanotube (CNT) composite powder. The composite powder was then melt-mixed with a twin-roll masticator to obtain a PP/CNT composite. The morphology of the PP/CNT powder and the PP/CNT composite was investigated. The crystallization and mechanical properties of the latter were also studied. After 20 milling cycles (ca. 60min), the average diameter of PP/3wt% CNT composite powder particles was a few micrometers. The length of the CNTs was reduced from a few micrometers to 0.4-0.5
