Abstract

Low density polyethylene (LDPE)/maleic anhydride grafted polyolefin elastomer (POE-g-MA) with multiwall carbon nanotubes (MWCNTs) wrapped by fumed silicon dioxide (SiO ₂) were prepared by melt mixing. The results revealed that SiO ₂ improved the dispersion of MWCNTs on matrix. SiO ₂ and MWCNTs both had a heterogeneous nucleation effect on matrix and the crystallinity of composites increased with adding SiO ₂, MWCNTs and MWCNTs/SiO ₂. The addition of MWCNTs modified by SiO ₂ increased tensile strength and elongation at break of composites compared with composite with raw MWCNTs. MWCNTs had a strong absorption effect, leading to an obvious decrease in reflectance at 1060 nm of composites.
