ABSTRACT:
Replacement of the amorphous peptide domain of a structural biopolymer, such as silk from silkworms or spiders, with a nonpeptide segment while maintaining the β-sheet forming crystalline segments provides synthetic multiblock copolymers having solid-state structures and mechanical properties similar to the naturally occurring structural biopolymer is described herein. Such synthetic multiblock copolymers may be produced as films or fibers.
