Abstract
Carbon nanotubes (CNTs) have drawn much attention in recent years and can be composited with polymers for various purposes of engineering. CNTs are difficult to be dispersed in polymer matrix, therefore, CNTs-composites are always challenged by weakness arising from interfaces and tube aggregation. In this research, we find a facile method by heat treatment that loaded CNTs can be redistributed in epoxy matrix and mechanical, thermal and electrical properties are improved accordingly.
