摘要(Abstract)：
讨论了纤维素在多聚磷酸溶液中的溶解情况和液晶性。采用适当的配比,纤维素能够溶解于多聚磷酸并形成各向异性溶液,在偏振光显微镜下可观察到彩色图片。溶液温度、纤维素聚合度、纤维素浓度对液晶性均有影响。溶液受热后,彩色图像会消失。
It is found liquid crystalline solutions can be formed when cellulose is dissolved in polyphosphoric acid. Under the polarization microscope, the anisotropic solution displays a bright and colourful image. Unpon heating, the colours start to fade until a dark field appears.
