Preparation of silver nanowire-polypyrrole/polyethersulfone flexible composite conductive film
Polyethersulfone/silver nanowire was used as organic flexible substrate and polypyrrole as polymer conductive medium to prepare the silver nanowire-polypyrrole/polyethersulfone flexible composite conductive film.The structure and conductivity of the film were tested.The results show that the compatibility of silver nanowires,polyethersulfone and polypyrrole is good.The main components of the surface of conductive film are Ag(59.7%),C(33.2%),O(2.8%),and S(3.4%).When the mass fraction of polypyrrole is 20%,the resistivity of the composite conductive film is 3.5 Ω·m,its conductivity is 9.7 S/cm,and its AC conductivity is 2.7×10-5 S/m.Through the electrochemical impedance spectroscopy test of the composite conductive film,the reaction time of the preparation of the conductive film is determined to be 3 h.
