| Abstract: | Preparation of cellulose microcrystalline suspension,formation,influencing factor and mechanism of cellulose cholesteric liquid crystal are studied from broad leaf wood pulp.Cellulose microcrystalline size dis-tributions under different hydrolysis temperature are observed by optical microscopy.The surface of cellulose microcrystalline is characterized by FTIR.When the liquid crystal phase appears,the critical suspension con-centration is confirmed by polarizing microscope.The results show that the stable su... |
