New CO2 adsorbent containing aminated poly(glycidyl methacrylate) grafted onto irradiated PE-PP nonwoven sheet

A new CO2 adsorbent containing triethylamine (TEA) was prepared by radiation induced grafting of glycidyl methacrylate (GMA) onto polyethylene coated polypropylene (PE-PP) non-woven sheet followed by amination reaction. The degree of grafting (DOG%) was controlled by variation of monomer concentrati...

Description
Summary:A new CO2 adsorbent containing triethylamine (TEA) was prepared by radiation induced grafting of glycidyl methacrylate (GMA) onto polyethylene coated polypropylene (PE-PP) non-woven sheet followed by amination reaction. The degree of grafting (DOG%) was controlled by variation of monomer concentration and absorbed dose. The incorporation of aminated poly(GMA) was investigated by Fourier transform infrared (FTIR) and scanning electron microscope (SEM). The adsorbent with DOG of 350% and amination yield of 60% exhibited CO2 adsorption capacity of 4.52mol/kg at ambient temperature and pressure. •Preparation of a new aminated fibrous adsorbent for CO2 capturing.•Grafting of GMA onto PP-PE nonwoven sheet followed by amination.•Dependence of degree of grafting on monomer concentration and absorbed dose.•FTIR and SEM evidences of grafting and amination.•CO2 adsorbent with high adsorption capacity at ambient temperature and pressure.
