Photo-triggered CO2 release from mussel-inspired polymers

Using solar energy instead of traditional steam energy could be a promising strategy for saving the CO2 capture energy consumption. Here we report solar triggered efficient CO2 release from a mussel-inspired CO2 capture solvent. Crosslinking polyethyleneimine and polydopamine by the self-polymerization was applied to capture CO2 and efficiently release CO2 by photoirradiation. CO2 absorption rate was improved by increasing the dopamine content...
