Green synthesis of biodegradable polyurethane and castor oil-based composite for benign transformation of methylene blue

A series of polyurethane (PU), polyethylene glycol (PEG) and castor oil (CO) (ricin) based foams (PU-PEG, PU-PEG40/CO60, PU-PEG60/CO40 and PU-CO) were prepared and their catalytic activity for removal of methylene blue (MB) dye was evaluated. The prepared foams were characterized by FTIR, SEM and TG...
