摘要
导电聚合物涂层材料在电子传感器、金属防腐防污和电磁屏蔽材料等领域具有广泛的应用。然而,这些涂层通常存在脆性大、附着力弱等问题。本研究以漆酚、吡咯和六水合三氯化铁为主要原料,通过化学氧化合成法制备了聚吡咯杂化漆酚铁导电涂层。采用傅里叶变换红外光谱(FTIR)、扫描电子显微镜(SEM)、电化学工作站和万能试验机对涂层进行了表征和分析。结果表明,当吡咯添加量为70%时,U-Fe-P70导电涂层的力学性能最优,最大应力达26.56 KPa,与金属基材的附着力最佳,附着力达655 KPa,同时涂层表现出优异的耐化学介质性能。此外,将合成的涂层沉积到多孔海绵上,组装成压阻式传感器,表现出高灵敏度和稳定性,在柔性传感器领域显示出巨大的应用潜力。
Conductive polymer coatings have extensive applications in electronic sensors,metal anticorrosion and anti-fouling,and electromagnetic shielding materials.However,these coatings often suffer from high brittleness and weak adhesion.In this study,a polypyrrole hybrid lacquer iron conductive coating was synthesized using lacquer,pyrrole,and ferric chloride hexahydrate as the main raw materials through a chemical oxidative polymerization method.The coating was characterized and analyzed using Fouriertransform infrared spectroscopy(FTIR),scanning electron microscopy(SEM),an electrochemical workstation,and a universal testing machine.The results indicated that when the pyrrole content was 70%,the U-Fe-P70 conductive coating exhibited the best mechanical properties,with a maximum stress of 26.56KPa and the strongest adhesion to the metal substrate,with an adhesive strength up to 655KPa.Additionally,the coating demonstrated excellent resistance to chemical media.Furthermore,the synthesized coating was deposited onto a porous sponge to assemble a piezoresistive sensor,which exhibited high sensitivity and stability,showing great potential for applications in flexible sensors.
