Description

一种多层次宏孔-介孔-微孔聚合物衍生陶瓷吸附材料及其制 备方法
技术领域
本发明涉及多孔陶瓷材料技术领域,特别涉及一种多层次宏孔-介孔-微孔聚合物衍生陶瓷吸附材料及其制备方法。
背景技术
近年来,随着染料工业的迅速发展,染料废水表现出成分复杂、有机物浓度高、脱色困难、难降解物质多、毒性强等特点,严重污染水体环境,危害人体健康。多孔陶瓷因其具有质量轻、耐高温、抗热震、高强度、高化学稳定性和高比表面积等优点被广泛用于污水净化领域,对解决水资源短缺和构建和谐环境具有重大意义。传统的多孔陶瓷表现出吸附率低、吸附时间长、降解有机污染物效率低等缺点限制其在污水处理领域的应用。
利用陶瓷前驱体高温裂解转化为可设计的聚合物衍生陶瓷(PCDs)的研究越来越广泛。由于陶瓷先驱体在裂解过程中能逸出大量的气体,合成的PCDs可获得高比表面积及丰富的孔隙,将PCDs设计成多孔材料具有制备温度低、陶瓷组成和结构可设计、复杂构件易成型等优点。目前,利用陶瓷前驱体合成多孔PCDs的方法主要有发泡法、反应技术法、人工模板法及溶胶-凝胶法。直接发泡法和反应技术法制备的多孔PCDs仅具有连通的宏孔,其比表面积很低;人工模板法合成的多孔PCDs的孔尺寸、孔形貌和比表面积强烈依赖于模板本身的孔结构;溶胶-凝胶法合成的多孔PCDs陶瓷一般能形成均匀分布的介孔。利用上述方法合成的多孔PCDs均表现出孔径单一分布、孔径分布较窄、比表面积低的缺点,限制其在污水处理领域的应用。因此,开发兼具高比表面积和大量吸附质可进入孔隙的多层次多孔结构的PCDs吸附材料及催化剂载体至关重要。
