【摘要】：以聚合诱导胶体凝聚法、种子生长法、模板法和反相乳液法等制备方法为主线,综述制备微米二氧化硅微球的最新研究进展,同时以所得微球的性能为考察重点,对各种方法进行评价与展望;提出通过硅酸钠等低成本硅原料取代硅酸酯制备高性能硅微球是未来研究重点;改变种子生长法中溶剂的种类、制备粒径更大的单分散微球并进行理论探究成为种子生长法的研究方向;采用模板法对聚合诱导胶体凝聚法制备的微球孔结构进行重组完善,得到纯度较高、机械强度和比表面积较大的微米有序介孔二氧化硅微球,进而用于高性能色谱柱的制备以及生物催化等领域,发展前景可观。
[Abstract]:The recent progress in the preparation of micron silica microspheres was reviewed with the methods of polymerization induced colloid condensation, seed growth, template method and inverse emulsion method as the main lines, and the performance of the obtained microspheres was also investigated. Various methods are evaluated and prospected. It is proposed that the preparation of high performance silicon microspheres by substitution of silicon silicate with sodium silicate and other low-cost silicon raw materials is the focus of future research, and the kinds of solvents in seed growth method should be changed. The preparation of monodisperse microspheres with larger particle size and theoretical exploration became the research direction of seed growth method, and the pore structure of the microspheres prepared by polymer-induced colloid condensation method was improved by template method, and the purity of the microspheres was high. Micron ordered mesoporous silica microspheres with large mechanical strength and specific surface area are widely used in the preparation of high-performance chromatographic columns and biocatalysis.
