Technical Abstract: Supercritical carbon dioxide (scCO2) high pressure and microwave reactor are considered in green chemistry as a substitute for organic solvents in chemical reactions. In this presentation, innovative approaches for preparation of flame retardant fabrics were obtained by utilizing supercritical carbon dioxide and microwave with minimum amount of co-solvent. Our attempts at flame retardant cotton fabrics treated with low cost inorganic formulations or a novel environmentally friendly phosphorus-nitrogen containing small molecules in scCO2 and microwave were done successfully. Furthermore, the flame retardant fabrics have been prepared by the layer-by-layer method of branched polymer containing phosphorus-nitrogen, clay, and inorganic formulations on cotton fabric. The evidence of flame retardant chemical penetrations or surface modification of cotton fabrics were confirmed by the Fourier transfer infrared spectroscopy (FT-IR), elemental analysis (EA) and scanning electron microscope (SEM), and the treated cotton fabrics were evaluated flammability tests such as 45 degree angle (clothing textiles test -- ASTM D1230-01; 16 CFR 1610) and vertical (ASTM D6413-08; 16 CFR 1615, 1616). In addition to the thermal properties of desired products will discuss by thermogravimetric analysis (TGA) and micro-scale combustion calorimeter (MCC).
