Interpretive Summary:

Technical Abstract: Due to its environmentally friendly properties, supercritical carbon dioxide (scCO2) is 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 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 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).
