Description

一种阻燃凹凸棒土/聚丙烯酸纳米复合凝胶及其制备方法
技术领域
本发明涉及一种凹凸棒土载体及其制备,尤其涉及一种阻燃凹凸棒土/聚丙烯酸纳米复合凝胶及其制备方法。
背景技术
药物载体释放和靶向系统能够减少药物降解及损失,降低副作用,提高生物利用度,因而对它的研究越来越受到重视。高分子表面活性剂由于其独特的两亲性结构,可以进行自组装,形成各种形式的聚集体,如胶束、微乳液、凝胶、液晶、囊泡等。这些聚集体具有包载药物分子的能力,同时又对膜有良好的渗透性,成为药物载体的重要研究领域。凹凸棒土是一种以凹凸棒石为主要组分的,具有特殊纤维状晶体结构形态的含水富镁铝硅酸盐矿物。由于其优异的吸附性、离子交换、流变性、催化性和可塑性,而被应用于制备药物载体。
朱龙祥在其硕士学位论文《原位聚合制备凹凸棒/聚合物纳米复合材料中的凝胶现象及应用》中,利用凹凸棒土和丙烯酸制备了纳米复合水凝胶,但是其作为药物载体使用,还存在着载附量、抗菌性、缓释性欠佳的问题。
发明内容
基于以上思考,本发明旨在提供一种载附量大、抗菌性好的药物载体用纳米复合水凝胶,及其制备方法。
本发明所要解决的技术问题采用以下的技术方案来实现 :

所述盐酸溶液浓度为2-6mol/L;硫酸锌溶液为0.5-1mol/L。
所述的一种阻燃凹凸棒土/聚丙烯酸纳米复合凝胶及其制备方法,其特征在于,由以下步骤制成:
a. 将凹凸棒土在120-160℃下烘烤1-3h,去除其中的有机化合物后,分散于蒸馏水中,再加入盐酸溶液、硫酸锌溶液进行活化和离子交换吸附,再将聚磷酸铵和硼酸锌加入并混合搅拌 20min,使聚磷酸铵和硼酸锌进入凹凸棒土纳米孔道当中,并且表面富含硅羟基,有锌离子吸附;
b. 将步骤a所得凹凸棒纳米棒晶分散到无水乙醇中,加入硅烷偶联剂KH-570、硅烷偶联剂KH-550、壳聚糖,超声分散1-3h后,60-90℃回流20-26h,反应完成后用无水乙醇洗涤2-5次,干燥后,得到碳碳双键接枝和氨基接枝、壳聚糖接枝的凹凸棒纳米棒晶;
c. 将步骤b所得凹凸棒纳米棒晶分散到蒸馏水中,超声分散1-2h后,加入硝酸铈、纳米氧化铜、丙烯酸,氮气保护、磁力搅拌条件下,于50-80℃反应18-25h,用蒸馏水洗去未反应的丙烯酸和聚丙烯酸,即得纳米氧化铜、壳聚糖加强的凹凸棒土/聚丙烯复合凝胶。
所述的一种阻燃凹凸棒土/聚丙烯酸纳米复合凝胶及其制备方法,其特征在于,步骤b中的干燥条件为30-50℃下真空干燥20-26h。
