Thermal degradation studies of 2-amino 6-nitrobenzothiazole-oxamide-formaldehyde copolymer and its composites

Abstract

Composites are viewed as promising advanced materials because of their superior features, including enhanced flame retardancy, density, relatively large surface areas, strength and thermomechanical/optoelectronic/magnetic capabilities. 2-amino 6-nitrobenzothiazole, oxamide, and formaldehyde has been used for the synthesis of copolymerizing polycondensation technique, and newly synthesized copolymer with activated charcoal was used to synthesize its composite. Several physicochemical techniques, and Ultraviolet-visible, SEM, TGA, and FTIR techniques, have been utilized to illustrate the produced copolymer and its composite. The non-aqueous conductometric titration was used to determine the molecular weight of the 2-amino 6-nitrobenzothiazole-oxamide-formaldehyde copolymer.based on TGA data, thermal stability of the composite is higher than copolymer, possibly because there are more carbonized residues. Based on Ea values determined by Sharp-Wentworth and Freeman-Carroll technique for copolymer and its composite, it is observed that they are in good agreement with each other. It is abundantly obvious from the results of the sequence of reaction that the decomposition reaction roughly follows a first-order kinetics. The composite's higher surface area, porous makeup, and smaller particle size may have contributed to its superior performance. The copolymer and its composite have better heat stability.
