| Abstract: | Calcium stearate modified nano-CaCO3(CaSt-nano-CaCO3) was prepared,and iPP /calcium stearate modified nano-CaCO3(iPP/CaSt-nano-CaCO3) was prepared by melt blending iPP with CaSt-nano-CaCO3 particles.Compared with pure iPP,the addition of CaSt-nano-CaCO3and nano-CaCO3particles both increased flexural strength and flexural modulus of iPP,and impact strength was also improved in these two series composites.In comparison with iPP/nano-CaCO3,the impact toughness of iPP/CaSt-nano-CaCO3composites was improved slig... |
