Polyethylene (PE), one of the most widely used thermoplastic materials. Carbon nanotubes (CNTs) have extraordinary mechanical and electrical properties. Incorporating CNTs into polymers improves the mechanical properties and imparts some attractive properties to the polymer matrix. However, CNTs have aggregation problems and weak interfacial adhesion with the polymer matrix. In this study, non-covalent functionalized CNTs (BA-CNT) was prepared by ball milling using benzylacetic acid (BA). A masterbatch based on 80 wt% EGMA and 20 wt% BA-CNT was fabricated by melt compounding with PE to obtain PE/EGMA/BA-CNT composites. The successful functionalization of BA-CNT was demonstrated by XPS, FT-IR, and TGA. The morphology of the composites was characterized by SEM. The mechanical properties of the composites were revealed using DMA and tensile tests. In addition, the electrical conductivity and EMI shielding performance were investigated.
