Preparation and Properties of Polyvinyl Chloride/Carbon Nanotube Composites
The addition of carbon nanotubes(CNTs)can increase the strength and stiffness of polyvinyl chloride(PVC)while enhancing its electrical conductivity.In order to improve the adaptability and stability of PVC,the study synthesized PVC/CNTs composites with varying proportions and analyzed their tensile strength,thermal conductivity,electrical conductivity,and thermal stability to determine the optimal content of CNTs in the composite.The results show that with an increase in the mass fraction of CNTs,the tensile strength of PVC/CNTs composites first increase and then decrease.The introduction of CNTs improves the thermal conductivity of the composites.When the mass fraction of CNTs is 2.0%,the PVC/CNTs composite exhibits superior tensile strength,thermal conductivity,electrical conductivity,and thermal stability.
