Polyvinylamine-Containing Adsorbent by Radiation-Induced Grafting of N-Vinylformamide onto Ultrahigh Molecular Weight Polyethylene Films and Hydrolysis for CO2 Capture
A facile method involving radiation induced grafting of N-vinylformamide (NVF) into the microporous structure of ultrahigh molecular weight polyethylene (UHMWPE) film followed by hydrolysis was used to prepare polyvinylamine (PVAm) containing adsorbent for CO2 capturing. The grafting parameters such...
