Effects of solid-phase drawing on mechanical and electromagnetic shielding properties of CNTs/PP composites

Cailiao gongcheng, 2023
Using polypropylene (PP) as a matrix and carbon nanotube (CNTs) as a modified material to prepare CNTs/PP composites, the effects of solid-phase drawing and CNTs on properties of PP-based composites after solid-phase drawing were analyzed. Crystallization, mechanical and electromagnetic shielding properties of the composites were studied by wide angle ...
