This paper sheds new light on what effects the different dosage of Multi-walled Carbon Nanotube (MCN) plays on the mechanical properties of polypropylene/calcium carbonate whisker composites for seats. As a method. a twin roll mill is used to prepare the PP/ PP-g-MAH/CCW/ carbon nanotube composite with the surface modified MCN and modified calcium carbonate whisker. polypropylene (PP)... https://balboasurfandsstylers.shop/product-category/boys-tee/
