中文摘要：
调制具有近晶A(SmA)相－手征性向列相(N*)相转变的小分子液晶材料、手性和非手性光聚合单体及少量光引发剂的混合物，然后使用紫外光照射呈透明状态的混合物的平行取向的SmA 相、引发混合物中平行取向的光聚合单体的分子间发生交联反应形成平行取向的高分子网络，从而制备平行取向高分子网络/液晶复合材料。伴随着SmA－N*相转变，复合材料具有低温可见光和红外光透过、高温可见光透过但一定波长范围的红外圆偏振光被反射的特性。申请者将研究手性与非手性光聚合单体分子结构、紫外光照射强度与温度以及复合材料的组成与复合材料中高分子网络的微观结构之间的关系，高分子网络的微观结构与复合材料的N*相的平行取向程度之间的关系，手性光聚合单体的螺旋扭曲力和高分子网络的微观结构与复合材料的N*相的选择反射入射光特性之间的关系，为将来制备低温不隔光与热而高温只隔热的智能化建筑门窗玻璃贴膜和热敏红外光传感器件提供理论依据。

结论摘要：
调制具有近晶A（SmA）相—手征性向列相（N*）相转变的液晶材料、手性和非手性光聚合单体及少量光引发剂的混合物，然后使用紫外光照射呈透明状态的混合物的平行取向的SmA相、引发混合物中平行取向的光聚合单体的分子间发生交联反应形成平行取向的高分子网络，制备出了平行取向高分子网络/液晶复合材料。伴随着SmA—N*相转变，该复合材料具有低温可见光和红外光透过、高温可见光透过但一定波长范围的红外圆偏振光被反射的特性。课题组研究了调控胆甾相液晶螺距梯度的方法、紫外光照射强度与温度以及复合材料的组成与复合材料中高分子网络的微观结构之间的关系，高分子网络的微观结构与复合材料的N*相的平行取向程度之间的关系，手性光聚合单体的螺旋扭曲力和高分子网络的微观结构与复合材料的N*相的选择反射入射光特性之间的关系，为将来制备低温不隔光与热而高温只隔热得智能化门窗玻璃贴膜和热敏红外光传感器件提供理论依据。
