聚苯胺/聚氨酯互穿聚合物网络柔性导电线路的优化制备
Optimized Preparation of Flexible Conductive Lines of Polyaniline/Polyurethane Interpenetrating Polymer Networks
摘要
Abstract
Current flexible conductive lines have weak compatibility and mismatch of mechanical properties between the conductive material and the base material,which leads to a decrease in the conductivity of the conductive lines after deformation.This study used thermoplastic polyurethane(TPU)as the matrix and polyaniline(PANI)as the conductive material.PANI was polymerized in situ in the TPU matrix to prepare a flexible conductive circuit with a PANI/TPU interpenetrating polymer network(IPN)structure.The results of microstructural analysis indicate that conductive PANI successfully polymerized in the TPU matrix,PANI and TPU physically mixed at the molecular level,exhibiting microphase separation characteristics and good compatibility.Meanwhile,the conductive properties of the conductive lines were optimized based on Taguchi's method,and the results showed that the swelling temperature had the greatest influence on the conductivity of the conductive lines.The optimal combination of preparation parameters was obtained as follows:swelling temperature of 20℃,swelling time of 30 min,concentration of oxidizing agent of 0.5 mol/L,oxidizing time of 10 min,oxidizing temperature of 20℃,and the optimal conductivity of 0.237 S/cm.The prepared PANI/TPU-IPN conductive lines maintained good conductive stability after undergoing deformation,showing a broad application prospect in flexible electronic devices.关键词
