Scarcity of the antisolvent polymer dielectrics and their poor stability have significantly prevented solution-processed ultraflexible organic transistors from low-temperature. large-scale production for applications in low-cost skin-inspired electronics. Here. we present a novel low-temperature solution-processed PEI-EP polymer dielectric with dramatically enhanced thermal stability. https://hollandscountryclothinges.shop/product-category/safety-wellingtons/
