Polymer nanocomposites polymethyl methacrylate

To modify polycarbonates and derivatives of polymethyl methacrylate dichloroethane and dichloromethane media are used. To modify pol5winyl chloride compositions and compositions based on phenolformaldehyde and phenolrubber polymers alcohol or acetone-based media are applied. The FS of metal/carbon nanocomposites are produced using the above media for specific compositions. In IR spectra of all studied suspensions the significant change in the absorption intensity, especially in the regions of wave numbers close to the corresponding nanocomposite oscillations, is observed. At the same time, it is found that the effects of nanocomposite influence on liquid media (FS) decreases with time and the activity of the corresponding suspensions drops. 

Hu et al. [122] found that in silica-polymethyl methacrylate nanocomposites, the Tg increased with increasing silica content. Also, other thermal properties were enhanced by incorporating silica into the polymer matrix for example, polymer degradation temperature was about 30°C higher than for virgin polymethyl methacrylate.
