摘要: 通过偏光显微镜和差示扫描量热仪(DSC)研究了碳纤维(CF)和滑石粉对聚酰胺6(PA6)结晶行为的影响。结果表明,CF的加入在PA6和CF的界面诱发横晶,CF和滑石粉在PA6基体中起到了异相成核作用,改变PA6的成核机理和晶体生长方式,提高了起始结晶温度和结晶速率。结晶速率随普等温结晶温度的升高而下降。当冷却速率增大时,起始结晶温度下降,结晶度增大。

Abstract: Polarizing microscopy and DSC were used to investigate the effect of carbon fiber and talc powder on the crystallization of polvamidc 6.It showed that carbon fiber could lization of PA6.Carbon fiber and talc powder promoted the nucleation in matrix,induce transcrvstal-changed the crystal growth mode, and increased the crystalline rate and the onset crystallization lization temperature.When the cooling rate increased, the onset crystallization temperature was elevated and the degree of crystallinity was also enhanced.
