| 摘 要： | 熔融挤出制备载银纳米二氧化钛(TiO2/Ag+)/聚丙烯(PP)复合材料，采用差示扫描量热仪研究纳米(TiO2/Ag+)对PP结晶性能的影响。结果表明:少量纳米TiO2/Ag对PP有成核促进作用，提高了结晶速率，使结晶度增大;当纳米TiO2/Ag十质量份数超过1%时，PP结晶陛减弱，甚至起一定的抑制作用;纳米TiO2/Ag+能提高PP结晶温度，而对PP熔融温度影响不大。

| 关 键 词： | Nanocomposites of PP and TiO2/Ag+ were prepared by means of melt blending. the effect of TiO2/Ag+ nanoparticles on the crystallization of PP was studied using DSC. The crystallization rates and degree of crystallinity of PP were increased by addition of less than 1 wt% of TiO2/Ag+ nanoparticles.When the content of the latter exceeded 1 wt% the degree of crystallinity of PP was decreased.The presence of TiO2/Ag+ nanoparticles increased the crystallization temperature however had no effect on the melting point. |
