o--季铵化--n,n--双十二烷基壳聚糖/胆固醇的混合单分子膜性质研究
Keywords: 壳聚糖，衍生物，胆固醇，单分子膜
Abstract:
？制备o--季铵化--n,n--双十二烷基壳聚糖,用ftir、ea、1hnmr对其进行表征,并研究其与胆固醇的混合单分子膜性质。结果表明,随着胆固醇的摩尔分数从0.2增加到0.8,？o--季铵化--n,n--双十二烷基壳聚糖/胆固醇混合单分子膜的极限分子占据面积aex及崩溃压πc逐渐减小。混合单分子膜两组分分子间的作用力从相互吸引作用转变为相互排斥作用的转折点出现在胆固醇的摩尔分数为0.4时。胆固醇的摩尔分数为0.2时,混合单分子膜的相容性最好,体系最稳定。
