摘要：
The thermal stability of polymethylmethacrylate loaded with silica nnaoparticles is investigated. The temperature dependence of the mass of of polymethylmethacrylate-silica nanocomposites has been fitted accurately with a single Boltzmann-like dependence. The effect of surface functionalization, silica nanoparticles size, and silica nanoparticles concentration is reported. It was observed that the thermal stability of polymethylmethacrylate increases as the polymer matrix is filled with nanoparticles. Surface functionalization produced a modest increase in the thermal stability (compared to composites with silica nanoparticles without surface modification).
