Enhanced miscibility and strain resistance of blended elastomer/pi-conjugated polymer composites through side chain functionalization towards stretchable electronics
This work presents improved compatibility in an elastomer/pi-conjugated polymer blend through side chain functionalization of the electronic polymer. Poly[(3-(6-bromohexyl)thiophene)-ran-(3-hexylthiophene)] (P3Br(x)HT, x = 0%-100%) was synthesized (i) to improve miscibility with polybutadiene (PB) elastomer through altered pi-pi interactions and (ii) to covalently bond across phase-segregated interfaces. Functionalization led to morphology with reduced domain sizes to improve crack onset strain from 7% to 40%. Furthermore, UV-activated crosslinking reinforced mechanically weak interfaces and yielded at least an additional 40% increase in crack onset strain. Charge mobility in PB/P3Br(x)HT organic field-effect transistors showed minimal dependence on bromide concentration and no negative effects from crosslinking. Functionalization was an effective method to reduce brittleness in PB/P3Br(x)HT blends through morphology modification and crosslinking to improve stability towards strain for potential stretchable electronic applications.
