PMOs是以桥联倍半硅氧烷为前驱体,在表面活性剂为结构控制剂的条件下通过溶胶-凝胶法合成的材料,具有表面积高、孔道规则和孔径分布较窄等特点,是一种性能优异的新型功能材料。本文论述了PMOs近年来的发展现状,介绍了PMOs的结构特点,根据结构中桥联有机基团的不同将其分为三类;总结了通过不同的模板合成PMOs的方法,并对影响性能的外部因素进行了探讨;最后提出了几个PMOs研究工作面临的问题,并对PMOs的发展前景做了展望。
PMOs are materials synthesized by sol-gel method under the conditions of surfactant as a structural control agent, and have the characteristics of high surface area, narrow pore size and narrow pore size distribution. A new type of high performance functional materials. In this paper, the development status of PMOs in recent years is introduced. The structural characteristics of PMOs are introduced. According to the different bridging organic groups in the structure, they are divided into three categories. The methods for synthesizing PMOs by different templates are summarized, The external factors were discussed. Finally, some problems faced by PMOs research were proposed, and the prospects of PMOs were prospected.
