Abstract Biodegradable polymer electronics offer an innovative solution to the growing challenge of electronic waste, which are engineered disintegrate after a defined functional period. Here, new class graft copolymer is presented, ε‐poly‐L‐lysine‐ ‐oligo(3‐hexylthiophene) (EPL‐ g ‐O3HTs), synthesized by covalently grafting oligo(3‐hexylthiophene) onto biopolymer ε‐poly‐L‐lysine at three densities, resulting in copolymers containing 43, 65 and 90 wt.% O3HT ‐O3HT‐1, EPL‐ ‐O3HT‐2 ‐O3HT‐3, respectively). Benefiting from “guidance” on chains alignment, with optimized density exhibits extended conjugation length increased crystallite size O3HT. Thin films copolymers, upon doping, demonstrate appreciable conductivity under ambient conditions. ‐O3HT‐1 could be fully break down over 12 days enzymatic degradation. also displays excellent broad‐spectrum antibacterial activity against Gram‐negative Gram‐positive bacteria, attributed its high ɛ‐poly‐L‐lysine content. It further demonstrated versatility ‐O3HTs transient for electromyography sensors muscle signal acquisition as channel material organic electrochemical transistors. Combining tunable conductivity, controlled biodegradability, antimicrobial properties, ‐O3HT hold significant potential diverse applications, including skin implantable electronics, where degradable properties highly desirable.
