Advances in Stimuli-Responsive Organic Materials and Polymers toward Intelligent CO2 Capture

Abstract

Recent advances in carbon dioxide (CO₂) capture highlight the potential of stimuli-responsive organic materials and polymers as low-energy, tunable solutions for climate change. This review summarizes developments in covalent organic frameworks (COFs), metal organic frameworks (MOFs), porous organic polymers (POPs), and related organic materials that respond to external stimuli such as temperature, light, pH, redox, magnetism, and pressure for CO₂ capture. These materials enable controllable CO₂ adsorption and desorption, offering improved efficiency, selectivity, and recyclability. By outlining key mechanisms and feasibility of multi-stimulations, this review aims to support the rational design of scalable, energy-efficient stimuli-responsive materials for fundamental and industrial research of CO₂ capture.
