摘要

不同官能团对碳纳米管(CNT)的功能化影响了其在聚二甲基硅氧烷(PDMS)中的胶体行为，增强了碳纳米管与PDMS之间的界面相互作用。本文研究了碳纳米管功能化对碳纳米管- pdms纳米复合材料压力传感性能的影响。采用溶液混合法制备了4种不同的CNTs - pdms纳米复合材料，分别为原CNTs、羧化CNTs、羟基化CNTs和胺功能化CNTs，并通过模铸法制备了纳米复合材料薄膜。通过拉曼表征研究了纳米复合压力膜的形貌以及碳纳米管在PDMS中的分布。对重复压力循环的压力传感响应进行了研究。

Influence of Carbon nanotubes (CNT) Functionalization on CNT/PDMS Nanocomposite Pressure Sensor

The functionalization of carbon nanotubes (CNT) with different functional groups influences its colloidal behavior in polydimethylsiloxane (PDMS) and enhances the interfacial interaction between the CNTs and PDMS. This paper addresses the investigation of the effect of CNT functionalization on pressure sensing behaviour of CNT-PDMS nanocomposites. Four different CNT-PDMS nanocomposites based on raw CNTs, carboxylated CNTs, hydroxylated CNTs and amine functionalized CNTs were prepared using a solution mixing process and the nanocomposite thin films were prepared by mold casting. Raman characterization was carried out to investigate the morphology of the nanocomposite pressure films as well as distribution of CNTs in PDMS. The pressure sensing response was investigated for repetitive pressure cycles.
