热致液晶（LC70）／PET共混物的结构与性能

Structures and Properties of In-Situ Composites of LC70 / PET

摘要: 采用ＷＡＸＤ、ＤＳＣ、ＰＯＭ、ＳＥＭ和力学测试方法研究了ＬＣ７０／ＰＥＴ原位复合材料的结构与性能。结果表明，当ＬＣ７０／ＰＥＴ＜２０％时，ＬＣ７０对ＰＥＴ的结晶生长具有一定促进作用；当ＬＣ７０／ＰＥＴ＞３０％时，共混物结晶能力迅速下降，结晶放热和熔融焓明显降低。

Abstract: Structures and properlies of the blends of themotropic liquid crystalline polymer(LC70) and poly(ethylene terphthalatc) (PET) were invcstignted by using WAXD, DSC, SEM, POM and mechanical test. For the blends with the weight ratioes of LC70 / PET > 30%, W
