Main purpose

Under certain conditions, polyethylene imine solid materials can absorb a large amount of carbon dioxide in humid air, and the separation process is also very convenient. Carbon dioxide can be permanently encapsulated in polyethylene imine solid materials, and can also be extracted for use in other fields. This material can be reused and maintains ultra-high absorption efficiency as always. Polyethyleneimine also has strong adhesion ability and can effectively adhere cells, but it also has strong toxicity.
