Among the various types of carbon dioxide adsorbents, porous polymeric materials are highly suitable for CO₂ capture due to their large and tunable surface area, appropriate thermal/mechanical properties, low density, high physicochemical stability, rapid kinetics, strength, and high adsorption capacity. Porous polymers such as hypercrosslinked polymers (HCPs), covalent organic frameworks (COFs), porous organic polymers (POPs), conjugated microporous polymers (CMPs), and triazine-based covalent frameworks (CTFs) exhibit a CO₂ adsorption range of approximately 3 mmol/g to 6 mmol/g at a temperature of 273 K and a pressure of 1 bar. Each of the polymers has unique properties and challenges in the CO₂ adsorption process. For example, HCPs and CMPs have higher specific surface areas, while biopolymers have advantages over other polymers due to their biodegradability and low cost. CMPs are more widely used in electrical fields due to their lightweight raw materials, while HCPs, because of their easy and quick preparation compared to other POPs, may attract more attention from researchers. However, they require modifications to their surface to increase their adsorption capacity. The results of this study show that polymers can be used as efficient and sustainable tools for carbon dioxide capture and reduce greenhouse effects.
