| 摘 要： | 用共溶剂法制备了热致液晶聚酰胺/尼龙66分子复合材料.用DSC、FTIR、POM和SEM对复合材料的相容性进行了综合研究.DSC研究表明,不同组成共混物的熔点和结晶度均发生明显下降,当液晶含量达到50%时,共混物出现超分子液晶态,体系具有明显的相容特征;FTIR结果证实了聚酰胺液晶与尼龙66分子间氢键作用的存在;POM和SEM研究表明,由于分子间相互作用而使共混物成为共连续微结构,没有出现相分离.

| Abstract: | Thermotropic liquid crystalline polyamide(TLCP) and nylon-66 molecular composites are compounded by solution blend.Miscibility of composites are studied by DSC,FTIR,POM and SEM.DSC results show that composites melting points and crystallinity are reduced due to additional TLCP and composites exhibit supramolecular liquid-crystalline behavior in 50%TLCP ratio.The FTIR results indicate that there exist hydrogen bonding interaction between molecules of TLCP and nylon 66.POM and SEM results show that the blends exhibit a homogeneous structure,and no phase separation takes place. |
