摘要

The application of transparent conductive films in flexible electronics has shown promising prospects recently.Tannic acid(TA) was successfully applied to modifying the surface of polydimethylsiloxane(PDMS) to fabricate highly flexible,transparent and conductive Ag nanowires(NWs) based films.TA modification transformed the PDMS surface from hydrophobicity into hydrophilicity without decreasing the transparence.A sheet resistance(Rs) of 80 Ω/cm2 with an optical transmittance of 94％ was achieved,which was superior to that of indium tin oxide(ITO) films.More importantly,the TA layer enhanced the interaction between Ag NWs and the PDMS substrate.The Ag NWs films on TA modified PDMS substrate exhibited excellent stability in Rs when subjected to a bending test.
