采用小角X-射线散射法测定大孔交联聚苯乙烯树脂的结构，发现大多数大孔交联聚苯乙烯在数纳米至数十纳米的标度尺寸范围内具有分形结构，分形维数介于2和3之间。本研究还进一步探讨了交联度、致孔剂、功能基化反应及后处理对大孔交联聚苯乙烯分形结构的影响。
The structure of macroporous cross-linked polystyrene resin was measured by small-angle X-ray scattering. It was found that most macroporous cross-linked polystyrene has a fractal structure in the scale range of several nanometers to several tens of nanometers. The fractal dimension Between 2 and 3. In this study, the effects of crosslinking degree, porogen, functionalization reaction and post-treatment on the fractal structure of macroporous crosslinked polystyrene were further explored.
