Abstract:Utilizing the adsorption properties of carbon nanotubes (CNTs) with hexadecyltrimethylammonium bromide (CTAB), CNTs with moisture-sensing properties were prepared, and their composition was determined through infrared spectroscopy and thermogravimetric analysis. These CNTs were then incorporated into polyvinyl chloride (PVC) as an anti-static agent, and their moisture-sensing properties were studied on the volume electrical conductivity of PVC/CNTs composite materials under simulated humid conditions. The results showed that the organic modification of CNTs can reduce their swelling threshold in the composite material. When the addition of CNTs was 4% (by weight), the electrical conductivity of the PVC composite material after moisture treatment could increase by four orders of magnitude.
