    半刚性乙酰氧丙基纤维素的制备与液晶相转变的影响研究

    Study on Preparation of Semiflexible Acetoxy Propyl Cellulose and the Liquid Crystalline Phase Transition

      摘要
    • 摘要: 以羟丙基纤维素为原料，通过酯化反应合成了分子量较高的乙酰氧丙基纤维素，并用ＦＴ－ＩＲ表征了化学结构。以ＤＳＣ，Ｘ－ｒａｙ衍射ＰＬＭ和ＳＡＬＳ手段研究了产物的热致液晶相转变及其影响因素和溶致液晶性。实验表明，产物的乙酰基含量受合成温度和反应时间影响，其热致液晶的相转变温度和温域随乙酰基含量变化。
