摘 要: 采用挤出成型制备了聚酰胺(PA)6/热致聚酰胺液晶(TLCPa)原位复合材料,研究了共混物的相容性、结晶性能和形貌。结果表明:TLCPa和PA 6具有较好的相容性,并存在分子间氢键作用:TLCPa掺入到PA 6的结晶过程中降低了PA 6的结晶度;PA 6的球晶大小随w(TLCPa)的增加而增大,当w(TLCPa)为30.0%时,出现,γ晶型;TLCPa在PA 6基体中形成长径比较大的增强纤维。 Polyamide(PA) 6/thermotropic liquid crystalline polyamide (FLCPa)/in situ composites were prepared by extrusion molding, The miscibility, crystallization properties and morphology of the blends were studied. The results show that TLCPa and PA 6 are well miscible and hydrogen bonds exist between the polymer molecules. The involvement of TLCPa in the crystallization process of PA 6 lower the latter's crystallization degree. The size of PA 6 spherulite augments with the increase of TLCPa content, y crystal form appears when the TLCPa mass fraction reaches 30.0%. TLCPa forms reinforced fiber with the large slenderness ratio in the PA 6 matrix.
