Polyester Modification Through Synthesis of Copper Nanoparticles in Presence of Triethanolamine Optimized with Response Surface Methodology

In this paper, polyester fabric was modified through synthesis and fabrication of Cu/Cu2O nanoparticles using a facile and cost-effective method at boil by chemical reduction through exhaustion route. Triethanolamine (TEA) was used for aminolysis of polyester fabric and pH adjusting, copper sulfate (CuSO4) as metal salt, sodium hypophosphite (SHP) as reducing agent and polyvinylpyrrolidone (PVP) as stabilizer. A response surface methodology was also employed to optimize the reaction conditions and study the effects of SHP, PVP and TEA concentrations in the processing. The images of fieldemission scanning electron microscopy (FESEM), the patterns of energy-dispersive spectroscopy (EDX) and X-ray diffraction (XRD) patterns confirmed successfully synthesis of Cu and Cu2O nanoparticles on the polyester fabric. Further, the thermal behavior of the untreated and treated fabrics was studied by using thermogravimetric analysis (TGA) and differential scanning colorimetry (DSC). The treated fabrics indicated good properties regarding wettability and flameretardant along with high tensile strength.
