Abstract
Provided is an electrically conductive elastomer with high stretchability and high durability. A method of synthesizing an electrically conductive elastomer includes (a) preparing a eutectic solvent by mixing quaternary ammonium salt and organic acid, and (b) adding and blending the eutectic solvent with poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), a photocuring agent, and a crosslinker and performing photopolymerization.
Claims10
A method of synthesizing an electrically conductive elastomer, the method comprising:
- (a) preparing a eutectic solvent by mixing and causing reaction between quaternary ammonium salt and organic acid;
- and
- (b) adding and blending the eutectic solvent with poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), a photocuring agent, and a crosslinker and then performing photopolymerization, wherein the polymerization of (b) prepares a polymer in which PEDOT:PSS nanoparticles have a coil-shaped benzoid structure;
- and transforming the coil-shaped benzoid structure of at least a portion of the PEDOT:PSS nanoparticles into a linear quinoid structure,
- wherein the photocuring agent and the crosslinker are blended in a molar ratio of 0.1 to 0.3 of the organic acid in step (b).
