光交联制备可拉伸有机半导体材料
Preparation of stretchable organic semiconductors through photocrosslinking
摘要
Abstract
Organic semiconductor materials exhibit promising prospects for flexible device applications due to their excellent solution processability and superior charge transport performance.This work proposed a method for preparing a stretchable organic semiconductor material.By using benzophenone as a photoinitiator,the conjugated polymer 3,6-dithiophene-2-yl-2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-diketone(4Si)was crosslinked with polydimethylsiloxane.The alterations in the electrical and mechanical properties of the polymer films were thoroughly investigated on both pre-and post-crosslinking.Compared to the uncrosslinked 4Si and blend films,the electrical properties of the crosslinked films slightly decreased,while the mechanical properties were enhanced.The crack onset-strain has increased from 30%to 50%.Furthermore,at 100%strain,the crosslinked film exhibited a mobility of 0.36 cm2·V-1·s-1 in the parallel strain direction,which is 1.44 times higher than the initial mobility.关键词
