Poly(methyl methacrylate) (PMMA) Nanocomposites

The research work reports the fabrication and characterization of PMMA nanocomposites using various nanofillers such as nanoclay (OMMT), Co-Al LDH, Cu-Cr LDH and Ni-Al LDH. The melt intercalation and solvent blending techniques were employed for the preparation of PMMA nanocomposites. The different properties of PMMA nanocomposites were examined by using XRD, TEM, FESEM, FTIR, DSC, TGA, DMA, tensile, flexural, impact, hardness, flammability and rheological analysis. The initial part addresses the fabrication and characterization of PMMA/OMMT nanocomposites by melt intercalation technique. Thereafter, the influence of different compatibilizers on the properties of PMMA/clay nanocomposites is discussed. The further section deals with the development of layered double hydroxides (LDHs) based PMMA nanocomposites (PMMA/Co-Al LDH, PMMA/Cu-Cr LDH and PMMA/Ni-Al LDH) containing various concentration of LDHs (1-7 wt.%). Subsequently, the final part describes the characterization of PMMA/OMMT, PMMA/Ni-Al LDH and PMMA/Co-Al LDH nanocomposites prepared by solvent blending method.
