Thermal degradation study of polymethylmethacrylate with AlI3 nanoadditive

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 (AlI3 NAs). In the present research work, a thermal degradation study of PMMA blends with AlI3 NAs was carried out by using a specially designed pyrolytic assembly. Different blends of PMMA with AlI3 (P0, P3, P6, P9, P12, and P15) were prepared by changing the concentration of AlI3 NAs from 0% to 15%. FTIR and TGA studies show the stability of polymers with AlI3 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 AlI3 NAs.

Automated summary

The study introduced a new method of degrading PMMA materials using AlI3 NAs. The results showed that AlI3 NAs can enhance the stability of polymers and effectively retard the combustion rate of polymers.
