Using these equations, the activation energies were deduced to be 263 and 261 kJ/mol for PMMA in DMF, and 198 and 198 kJ/mol for PMMA in THF. Kissinger and FWO equations were used to analyze the kinetic data obtained at different heating rates. The nanocomposite with the highest glass transition temperature of 111 ☌ was the one containing 0.25 wt% MWCNT-OH. Both MWCNT and MWCNT-OH increased the glass transition temperature of PMMA. Processing of plastic PMMA has a certain degree of water absorption of 0.3-0.4. PMMA is an amorphous polymer, the melt temperature is above 160 Celsius degree and the decomposition temperature can reach 270 Celsius degree. (THF, toluene and chloroform), keeping the total polymer. In molding, it changes the melt viscosity mainly from the injection molding temperature. Thermal degradation of nanocomposites occurred in three steps, similar to PMMA. polydimethylsiloxane (PDMS) and polymethylmethacrylate (PMMA) in three different solvents. Morphological studies showed that MWCNT were well dispersed in the polymer matrix. ![]() The starting components and nanocomposites were characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). This study represents the processing, characterization and thermal properties of poly(methylmethacrylate)/multi-walled carbon nanotube (PMMA/MWCNT) and PMMA/MWCNT-OH nanocomposites prepared using the solution casting method.
