| Abstract: | Improving the processing performance of polymers is an eternal topic in the polymer field. As a processing aid, solid lubricants improve the shortcomings of liquid lubricants that are easy to migrate. In this work, silicone powder was introduced into polyarylene ether nitrile (PEN)/multi-walled carbon nanotubes (MWCNTs) composites as a solid lubricant to improve the flowability and processability. Firstly, the effects of silicone powder and MWCNTs on the mechanical properties, thermal properties, dielectric properties and rheological properties of the composites were investigated. The experimental results show that the fluidity of the composites is improved obviously by adding silicone powder. In addition, a comparative experiment was carried out. Compared with PEN/MWCNTs composites, PEN/silicone powder/MWCNTs composites have better processing properties and dielectric properties. The complex viscosity is 308.1 at 102 Hz and the dielectric constant is 1?×?105 at 103 Hz. Therefore, silicone powder is of great research value as a solid lubricant in the field of polymer-based functional materials. |
