Preparation and performance of PEDOT:PSS composite polyester/cotton conductive nonwoven
In order to prepare the nonwoven fabric with good electrical conductivity and service performance,the dense poly(3,4-ethylenedioxythiophene):sodium polystyrene sulfonate(PEDOT:PSS)conductive polymer was in-situ grown on the poly-cotton nonwoven fabric by in-situ polymerization method.The influence of technological parameters such as dopant volume ratio and oxidizer volume ratio on the performance of conductive nonwoven fabric was investigated.The results show that PSS∶APS∶EDOT ratio of 2∶1.5∶1,polymerization time of 10 h is the optimum process,the highest conductivity of the prepared conductive nonwovens is 29.044 mS/cm.The breaking strength and elongation of conductive nonwovens are 20.18 N and 85.23%respectively.The conductive fabric has good washing resistance and air permeability up to 329.19 mm/s,which provides reference for the application of conductive nonwovens in flexible electronics.
