Optically Assorted Electrospun Nanofiber Mats of Electroactive Blends for Flexible Electronics

Abstract

This study demonstrates a simple way of achieving nonwoven nanofiber mats of various conjugated polymers and small molecules possessing various optical absorption. The conjugated polymer studied are poly (3,4-ethylene dioxylene thiophene):poly(4-styrene sulfonic acid) (PEDOT:PSS) and poly 3-hexyl thiophene (P3HT). The conjugated small molecules considered are thiophene-2, 1,3-benzothiadiazole -thiophene (TBT) and 7, 9-di (thiophen-2-yl) 8H cyclopenta[a]acenaphthylen-8-one (DTCPA). The blend polymer used along with four conjugated materials for electrospinning is poly (ethylene oxide) PEO. Effect of optimized electrospinning and its parameters on the morphology and structure is evaluated. Thus with the free-standing colorful electroactive nanofiber mats an attempt towards solar-cloth has been presented.
