Microporous organic polymers (MOPs) with internal pores less than 2 nm have potential use in gas separation, sensing, and storage, in the form of membranes, monoliths, fibers, or adsorbent granules. These covalently bonded polymers are being formed by reacting with rigid organic monomers, and MOPs have lately been studied for capturing CO₂ from gas mixtures in the form of membranes and adsorbents. Especially, the potential of MOPs in the processes of carbon capture and storage has been in the focus and small pore MOPs are preferred for regular separation processes but larger pores could be suitable if cryogenic processes would be used. Recent studies (2014 – mid 2019) on the potential use of MOPs as CO₂ adsorbents and, to some degree, CO₂-selective membranes are reviewed.

内部孔小于2 nm的微孔有机聚合物（MOP）可能以膜，整料，纤维或吸附剂颗粒的形式用于气体分离，传感和存储。这些共价键合的聚合物是通过与刚性有机单体反应而形成的，最近已经研究了MOPs以膜和吸附剂的形式从气体混合物中捕获CO ₂。特别是，在碳捕获和储存过程中，MOP的潜力已成为焦点，对于常规分离过程，小孔MOP是优选的，但如果使用低温过程，则较大的孔可能是合适的。关于MOPs作为CO ₂吸附剂以及一定程度上CO ₂的潜在用途的最新研究（2014年至2019年中期）对选择性膜进行了综述。
