Rapid industrialization in the past century has led to a surge in energy demand, predominantly met by fossil fuels. This reliance results in significant CO2 emissions, a primary contributor to the greenhouse effect. To address the escalating climate crisis, many countries are exploring strategies like CO2 capture and storage (CCS). Recognized for its potential in aiding climate change targets, CCS offers solutions for low carbon power, industrial decarbonization, and even facilitates net CO2 removal from the atmosphere. In this research, we developed and assessed Mixed Matrix Membranes (MMM) infused with Carbon-modified Polymers of Intrinsic Microporosity (PIMs) to enhance CO2 separation efficiency.
