Differential Thermal Analysis of Polyvinyl Alcohol Nanocomposite with Rice Husk Ash as a Filler

Abstract

Abstract Nanoparticles of polyvinyl alcohol with rice husk ash as a filler for strong polymer material candidates have been prepared through the sol-gel method. Rice husk ash is a waste product obtained from the combustion of rice husks at a controlled temperature and possesses high pozzolanic properties due to its silica content. Ball milling and co-precipitation methods were employed on the rice husk ash to create nanoparticle materials. To produce nanocomposite membranes, a polyvinyl alcohol solution was utilized as a solvent through the sol-gel method. The nanocomposite samples of rice husk ash were analyzed thermally to determine the material’s response to temperature. Various nanocomposite compositions of polyvinyl alcohol and rice husk ash were used, including 0%, 1%, 2%, 3%, and 4%. Based on the thermal analysis, it is evident that there were changes in enthalpy (H) and mass characteristics in all five samples.
