Preparation and characterization of composite polyester fabric with silver and conductive copolymer
To enhance the conductivity of polyester fabric and broaden its application potential in the realm of flexible electronic devices,the conductive composite polyester fabric was prepared by solution polymerization and magnetron sputtering with aniline and pyrrole as monomers and nano-silver as the target material.The growth model of nano-metal film on the surface of flexible fiber was probed.Additionally,we examined how varing magnetron sputtering times impacted the microstructure,crystallization performance,chemical structure,and electrochemical performance of composite fabric.The results show that the nano silver grown by magnetron sputtering mainly grows on the surface of the flexible fabric substrate in a'layered-island mode'.As spattering time increases,the nano silver film particles become increasingly uniform;however,excessively long time results in roughness.The metallic silver film shows good uniformity and compactness when the sputtering time is 900 s.The electrochemical performance of the composite fabric can be further improved by magnetron sputtering silver metal.When the sputtering time is 900 s and the current density is 1 mA/cm2,the area specific capacitance of the fabric reaches a peak of 67.1 mF/cm,which is approximately 3.3 times higher than that of PANI-PPy/PET.These findings suggest promissing applications for functional conductive textiles.
