WebMar 27, 2024 · The SEM analysis showed the uniform distribution of boehmite in the PMMA matrix. The shift in glass transition and melting temperatures to higher temperature domains were revealed by DSC analysis. From the TGA studies, the reinforcement of PMMA with boehmite nanoparticles increases thermal stability. WebFigure 2 shows the DSC results when the samples were quenched rapidly. As seen in Figure 1, glass transition (Tg) occurred around 60 °C for all samples. Melting occurred with endothermic peaks at 150 °C and 170 °C for Sample b and Sample c/ c', respectively. These
