摘要: 采用示差扫描量热法(DSC)研究了纳米碳纤维对PP/CNF复合材料中PP结晶行为的影响。结果表明:纳米碳纤雏可提高PP的结晶温度,但略降低其结晶速率和结晶度。提高纳米碳纤雏含量或减小纳米碳纤雏直径,PP结晶行为的上述变化更为明显,但结晶速率随纳米碳纤维含量出现先减小后增大的趋势。Abstract: The effects of carbon nanofiber on the crystallization behavior of polypropylene in PP/CNF composites were studied with differential scanning calorimeter (DSC). The results show that the carbon nanofiber can heighten the crystallization temperature of po
