Abstract
Abstract Organic polymers in the process of thermal degradation produce a lot of toxic fragments. In this work, we designed a new method of degradation of polymethylmethacrylate (PMMA) materials with aluminum triiodide nanoadditives (AlI 3 NAs). In the present research work, a thermal degradation study of PMMA blends with AlI 3 NAs was carried out by using a specially designed pyrolytic assembly. Different blends of PMMA with AlI 3 (P0, P3, P6, P9, P12, and P15) were prepared by changing the concentration of AlI 3 NAs from 0% to 15%. FTIR and TGA studies show the stability of polymers with AlI 3 NAs. Scanning electron microscopy analysis shows All 3 spread uniformly at nanoscale throughout the polymer matrix. Horizontal burning test (HBT) test confirms that polymer burning is retarded with AlI 3 NAs.
