Efforts to capture CO₂ from anthropogenic sources as well as from the air are being continuously intensified as to battle the greenhouse gas effects and climate change. Capture by liquid solvent absorption, mainly involving amines, is the common industrial practice, yet capture relying on solid adsorbents is increasingly gaining interest due to its potential for less energy-demanding and more efficient operation. Despite the large variety of porous adsorbents being explored, such as zeolites, carbons, mesoporous silicas, graphene and related structures, polymers, and metal-organic frameworks, it still remains challenging to find a proper material to cover all the critical specifications, i.e. with respect to CO₂ capacity, selectivity, chemical and thermal stability, fast kinetics, cyclability, low energy consumption, low manufacturing cost, and mechanical robustness. To this end, combining highly CO₂-phylic amines with the most robust of the developed solid porous materials through functionalization of the latter is a highly promising approach. Consequently, particular emphasis is given to increase the number of amine functional groups per unit of support area, enhance CO₂-phylicity of the amines, and provide suitable diffusion pathways to enhance CO₂ capacity. Towards achieving this goal, use of amine-bearing polymer functionalities is being highly investigated. This work critically and comparably reviews current progress on polymeric amine - functionalized solid adsorbents and their performance in CO₂ capture. It examines works based on various polymers, including polyethylenimine, polypropylenimine, polyallylamine, polyaniline, amino dendrimers, and hyperbranched polyamines. Based on the extracted comparisons, optimal systems are proposed and envisioned and future trends and directions are stated.

从人为源以及从空气中捕获CO _2的努力正在不断加强，以与温室气体效应和气候变化作斗争。通过液体溶剂吸收（主要涉及胺类）进行捕集是常见的工业实践，然而，依靠固体吸附剂进行捕集由于其潜在的能源需求减少和更高效的运行而越来越受到关注。尽管正在研究各种各样的多孔吸附剂，例如沸石，碳，中孔二氧化硅，石墨烯和相关结构，聚合物以及金属有机骨架，但要找到一种适合所有关键规格的合适材料仍然存在挑战，即关于CO ₂容量，选择性，化学和热稳定性，快速动力学，可循环性，低能耗，低制造成本和机械强度。为此，将高CO _2-空间胺与最坚固的已开发的固体多孔材料通过功能化结合起来是一种很有前途的方法。因此，特别强调增加单位支撑面积上胺官能团的数量，增强胺的CO ₂亲和性，并提供合适的扩散途径以增强CO _2。容量。为了实现这个目标，正在高度研究含胺聚合物官能团的使用。这项工作批判性地和可比较地回顾了聚合物胺官能化固体吸附剂的最新进展及其在CO ₂捕获中的性能。它检查了基于各种聚合物的作品，包括聚乙烯亚胺，聚丙烯亚胺，聚烯丙胺，聚苯胺，氨基树枝状聚合物和超支化多胺。基于提取的比较结果，提出并设想了最佳系统，并指出了未来的趋势和方向。
