本文报道了一种室温下呈现手性液晶（N-*）相的（聚合物网络/手性液晶/手性掺杂剂）复合材料。由于手性掺杂剂的螺旋扭曲力随温度的升高而增加，并且聚合物网络影响液晶的分子重排，因此N-* 相的选择性反射光谱的带宽分别随温度的升高和降低而可逆地变宽和变窄。(C)2003年，美国物理学会。
A (polymer network/nematic liquid crystal/chiral dopant) composite exhibiting a chiral nematic (N-*) phase at room temperature has been developed. Because the helical twisting power of the chiral dopant increases with increasing temperature and the polymer network affects the molecular rearrangement of the liquid crystal, the bandwidth of the selective reflection spectrum of the N-* phase becomes wider and narrower reversibly with increasing and decreasing temperature, respectively.
