Organic–inorganic hybrid polyaspartimide involving polyhedral oligomeric silsesquioxane via Michael addition for CO2 capture



original image

Organic–inorganic hybrid polyaspartimide polymers were synthesized via Michael addition by using octa(aminophenyl)silsesquioxane (OAPS) (2.5–30 wt %), leading to a family of porous polymers. The formation of [BOND]NH structure during Michael addition assists in CO2 capture. The CO2 capture capacity increased with increasing concentration of OAPS from 2.5 to 25 wt % in the PAI/OAPS polymers.
