Abstract Cholesteric liquid crystals microcapsules (CLCM) were prepared via complex coacervation method, which were further used as thermochromic materials in an intelligent functional fiber. The morphology of CLCM with core-shell structure was confirmed by SEM and TEM images. According to the TG results, CLC core took 52 wt% of the microcapsules. Thermochromic property of the CLCM was closely related to its particle size, and CLCM in the range of 3–30 μm had excellent thermochromic property producing color progressively moving from red to blue as the temperature was raised. The CLCM were added to polyvinyl pyrrolidone (PVP) solution and CLCM/PVP fibers were prepared by electrospinning method. The thermochromic performance of CLCM/PVP fibers was in accordance with CLCM, and the optimal particle size of CLCM for preparing CLCM/PVP fibers was 3–10 μm.

智能功能纤维用热致变色液晶微胶囊的制备

摘要 采用复合凝聚法制备了胆甾型液晶微胶囊（CLCM），进一步用作智能功能纤维的热致变色材料。通过SEM和TEM图像证实了具有核壳结构的CLCM的形态。根据 TG 结果，CLC 核心占微胶囊的 52 wt%。CLCM 的热致变色性能与其粒径密切相关，3-30 μm 范围内的 CLCM 具有优异的热致变色性能，随着温度的升高，颜色逐渐从红色变为蓝色。将CLCM加入到聚乙烯吡咯烷酮(PVP)溶液中，通过静电纺丝法制备CLCM/PVP纤维。CLCM/PVP 纤维的热致变色性能与 CLCM 一致，
