Abstract：Conventional conjugated polymers face the critical chalenge 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 styrenebutadiene 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 （204号 1.08cm2⋅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，showcasingexceptional stretchability.
