自二十年前发明以来，多孔聚合物整体柱已经取得了长足的发展。虽然早期的研究应用了当时用于制备聚合物颗粒的传统聚合工艺，但对整体柱结构感兴趣的科学家们的创造力后来促使他们使用了许多不太常见的技术。这篇综述文章介绍了在此期间出现的各种各样的方法。本文首先简要描述了用于制备整体柱的早期方法，包括标准的自由基聚合，并涵盖了它们直至今日的发展。特别关注了工艺变量对多孔结构形成和孔表面化学的影响。还特别关注了光聚合的使用。然后，更详细地介绍了几种不太常见的自由基聚合技术，例如由γ射线和电子束引发的技术、从高内相乳液制备整体柱以及冷冻凝胶技术。还讨论了包括稳定自由基、原子转移自由基聚合和开环易位聚合在内的活性聚合过程。综述最后描述了基于缩聚和加聚反应以及沉淀预制聚合物以获得整体材料的制备方法。
The porous polymer monoliths went a long way since their invention two decades ago. While the first studies applied the traditional polymerization processes at that time well established for the preparation of polymer particles, creativity of scientists interested in the monolithic structures has later led to the use of numerous less common techniques. This review article presents vast variety of methods that have meanwhile emerged. The text first briefly describes the early approaches used for the preparation of monoliths comprising standard free radical polymerizations and includes their development up to present days. Specific attention is paid to the effects of process variables on the formation of both porous structure and pore surface chemistry. Specific attention is also devoted to the use of photopolymerization. Then, several less common free radical polymerization techniques are presented in more detail such as those initiated by γ-rays and electron beam, the preparation of monoliths from high internal phase emulsions, and cryogels. Living processes including stable free radicals, atom transfer radical polymerization, and ring opening metathesis polymerization are also discussed. The review ends with description of preparation methods based on polycondensation and polyaddition reactions as well as on precipitation of preformed polymers affording the monolithic materials.
