多孔高聚物作为功能材料,如色谱固定相、离子交换剂、催化剂载体、高分子试剂以及富集材料等,已得到广泛的应用。测定这些材料孔径的大小及其分布情况,对于探索其制备方法,研究其结构与性能的关系有重要意义。测定孔径的常见方法有毛细管凝聚法、压汞法及电子显微镜方法等。这些方法虽然比较精确,但操作过程较为复杂。 Porous polymer as a functional material, such as chromatographic stationary phase, ion exchangers, catalyst carriers, polymer reagents and enrichment materials, has been widely used. Determination of the size of these materials and their distribution of pore size, for exploring its preparation method, study the relationship between structure and performance of great significance. Common methods for determination of pore size capillary condensation method, mercury injection method and electron microscopy methods. Although these methods are more accurate, the operation process is more complicated.
