摘要/描述

The outstanding strength and toughness of certain spider and lepidopteran silkst [1] has aroused considerable interest in recent years, [2] with research focusing primarily on the rela-tionship between molecular structure and mechanical proper-ties. [3] Environmental conditions such as ambient humidity, [4] acidity, [5] and UV radiation [6] a11 affect the mechanical proper-ties of native silks to some degre. [7] pronounced differences in mechanical properties were also observed when conditions such as the speed or temperature at spinning were varied [8] or when the silk was (or had been) submerged in solvents such as water, urea solution, or a range of alcohols, where it con-tracts in varying degrees.
