摘要
This study presents highly stretchable and photomodulated poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS)/poly(vinyl alcohol) (PVA) composite films with improved mechanical strength and controllable conductivity. By incorporating water-soluble PVA and physically cross-linking PEDOT:PSS and PVA using acetone as bad solvent for the polymers, the films achieve a maximum strain of nearly 770%. The addition of spiropyran as a secondary dopant enables the reversible control of PEDOT:PSS conductivity through photochromic properties. The findings highlight the potential of these composite films for various applications, offering stretchability and tunable conductivity.
