Synthesis and properties of poly(methyl methacrylate)/montmorillonite (PMMA/MMT) nanocomposites
Li, Y; Zhao, B; Xie, SB; Zhang, SM
AbstractPMMA/MMT nanocomposites were successfully synthesized via in situ intercalative polymerization, and characterized by means of wide-angle X-ray diffractometry, transmission electron microscopy, thermal gravimetric analysis, dynamic mechanical analysis and Fourier-transform infrared analysis. The nanocomposites possess partially exfoliated and partially intercalated structure, in which the silicate layers are exfoliated into nanometre secondary particles with thickness of less than 20 nm and uniformly dispersed in the polymer matrix. In comparison with pure PMMA, the thermal stability, glass transition temperature, and mechanical properties of the polymer are notably improved by the presence of the nanometric silicate layers. It was found that part of the PMMA chains in the nanocomposites are well immobilized inside and/or onto the layered silicates and, therefore, the unique properties of the nanocomposites result from the strong interactions between the nanometric silicate layers and the polymer chains.
