用同步红外显微镜研究了静态和剪切等规聚丙烯-液晶聚合物（iPP-LCP）纤维模型复合材料的界面，横向空间分辨率为3µm。利用光束的偏振，可以区分α和β跨晶（TC）相。结构证据表明存在一个α层，该层成核的β TC相与先前的形态学研究一致。
Abstract The interphase of quiescent and sheared isotactic polypropylene–liquid crystalline polymer (iPP–LCP) fiber model composites has been examined with synchrotron infrared microscopy down to a lateral spatial resolution of 3 µm. By using the polarization of the beam, it is possible to distinguish between α and β transcrystalline (TC) phases. Structural evidence is presented for the presence of an α layer that nucleates the β TC phase in agreement with previous morphological studies.
