多孔聚合物微球成孔技术的最新研究进展

摘要

综述了多孔聚合物微球的制备方法及成孔机理.种子溶胀法和微膜乳化法用于制备具有微孔、中孔结构的单分散聚合物微球;而大孔聚合物微球的制备通常采用传统的悬浮聚合,并通过后交联法改善其孔性能,提高其比表面积.%The preparation methods and pore-forming mechanisms of functional porous polymer particles were reviewed. In general, the microporous and mesoporous polymer particles with narrow size distribution can be prepared through shirasu porous glass-suspension polymerization and seeded swelling approach, while macroporous copolymers can be synthesized via traditional suspension polymerization. Both the specific surface area and the pore volume of macroporous copolymers can be increased significantly after post-crosslinking.
