硅氧烷侧链诱导共混薄膜垂直相分离构建可拉伸有机晶体管
Siloxane-side-chain-induced vertical phase separation in polymer blends for stretchable organic transistors
摘要
Abstract
Conventional conjugated polymers face the critical challenge of achieving simultaneous optimization of electrical and mechanical properties.This study focuses on siloxane-side-chain-functionalized diketopyrrolopyrrole(DPP)-based conjugated polymer(DPP-4Si)blended with hydrogenated styrene-butadiene block copolymer(SEBS).Through precise control of film preparation and microphase separation structures,we developed high-performance elastic semiconductor films with a maximum mobility of 1.08 cm²·V-1·s-1.Fully stretchable transistors fabricated using the optimal blend ratio demonstrated remarkable electromechanical stability,maintaining over 72%current retention even under 100%tensile strain,showcasing exceptional stretchability.关键词
