摘要

通过物理混合和原位还原的方法制备了纳米金/碳纳米管/聚二甲基硅氧烷(AuNPs/CNTs/PDMS)复合薄膜。扫描电子显微镜分析表明碳纳米管(CNTs)在PDMS中均匀分布。当CNTs含量为4%(wt,质量分数,下同)时,其与纳米金(AuNPs)形成相互连接的网络,复合薄膜具有导电性;CNTs含量为3%,AuNPs还原时间为8h时,复合薄膜灵敏度最高,应变系数为5.71。AuNPs/CNTs/PDMS复合薄膜具有良好的柔韧性和导电性,可广泛应用于柔性可穿戴设备。

Abstract

Nanogold/carbon nanotubes/polydimethylsiloxane (AuNPs/CNTs/PDMS) composite films were prepared by physical mixing and in-situ reduction methods.Scanning electron microscopy analysis showed that carbon nanotubes (CNTs) were uniformly distributed in PDMS.When the content of CNTs was 4% (wt,mass fraction,the same below),they formed an interconnected network with gold nanoparticles (AuNPs),and the composite film exhibited conductivity.When the content of CNTs was 3% and the reduction time of AuNPs was 8 h,the sensitivity of the composite film was the highest,with a strain coefficient of 5.71.The AuNPs/CNTs/PDMS composite films demonstrated excellent flexibility and conductivity and could be widely used in flexible wearable devices.
