摘要：Conducting polymers with inherently good flexibility and conductivity are good candidates for stretchable conductor applications, such as wearable electronics and healthcare devices. In this article, the crosslinked PAA (polyacrylic acid, n-PAA) hydrogels were fabricated via the reaction between hydrophilic groups of polymers in the presence of the water-based silicone crosslinking agent. By using the PEDOT:PSA (poly(3,4-ethylenedioxythiophene):polystyrene sulfonate-co-acrylic acid) as a conducting component, the conductive hydrogels prepared by this method are highly conductive with a value of 2.00 S cm(-1), highly stretchable with 800% strain and exceedingly stable in ambient air for a long time; also they possess superior properties to similar crosslinking methods. The resistance change with stretching is almost strain-insensitive up to 50% strain after 1000 fatigue cycles.
