| 摘 要： | 通过DSC,TGA,WAXD以及POM等检测方法研究了用共溶剂法制备热致液晶聚酰胺(TLCPa)与尼龙6(PA6)的复合材料的热性能和结晶行为。结果表明,随着TLCPa质量分数的增加,PA6/TLCPa30复合材料的起始降解温度较纯PA6提高了近27℃。结晶行为的研究表明,TLCPa的加入降低了结晶速度和结晶度,结晶受到抑制。XRD图谱证实TLCPa进入到PA6的结晶过程,少量TLCPa的加入并不影响PA6的晶体结构,PA6还是以α晶为主。当TLCPa的质量分数达到40%以上时,图谱出现非晶包。用POM观察,晶体边界模糊,晶体形貌有一定程度的细化。

| Abstract: | Composites based on thermal liquid crystalline polymer(TLCPa) and polyamide 6(PA6) were prepared using a solution-mixing technique in this study.Differential scanning calorimetry(DSC),thermogravimetry analysis(TGA),wide angle X-ray diffractometry(WAXD) and polarizing optical microscope(POM) were applied to study the compatibility,thermal stability and crystallization behaviour.The addition of TLCPa enhanced the thermal stability of PA6.The degradation onset temperature of composites with 30% TLCPa in weight... |
