ε-Poly-L-lysine-graft-oligo(3-hexylthiophene) Copolymers as Antibacterial and Biodegradable Polymer Electronics.

ABSTRACT: Biodegradable polymer electronics offer an innovative solution to the growing challenge of electronic waste, which are engineered to disintegrate after a defined functional period. Here, a new class of graft copolymer is presented, ε-poly-L-lysine-graft-oligo(3-hexylthiophene) (EPL-g-O3HTs), synthesized by covalently grafting oligo(3-hexylthiophene) onto the biopolymer ε-poly-L-lysine at three grafting densities, resulting in copolymers containing 43, 65 and 90 wt.% O3HT (EPL-g-O3HT-1, EPL-g-O3HT-2 and EPL-g-O3HT-3, respectively). Benefiting from the "guidance" of ε-poly-L-lysine on O3HT chains alignment, the graft copolymer with optimized grafting density exhibits an extended conjugation length and increased crystallite size of O3HT.
