Abstract Al-pillared-montmorillonite (AlPMt)/poly(methyl methacrylate)(PMMA) nanocomposites were synthesized via melt blending method (MBM) and solution blending method (SBM). FTIR-ATR spectroscopy proved the interaction of AlPMt with PMMA polymer matrix. The thermogravimetric and differential scanning calorimeter analyses showed that the thermal stability and the glass transition temperature (Tg) of polymer matrix shifted to higher temperatures with increasing AlPMt content. Images showed that AlPMt dispersed at nanometer scale in polymer matrix. Contact angle measurements demonstrated that the hydrophilicity of the PMMA increased with incorporation of AlPMt. However, the thermal stability of clay/polymer nanocomposites (CPNs) was significantly changed with CPN preparation method.

Solution Blending

Ternary blends of polylactide (PLA, 90 wt.%) and poly(methyl methacrylate) (PMMA, 10 wt.%) with functionalized polysilsesquioxanes (LPSQ-R) were obtained by solution blending. R groups in LPSQ containing hydroxyethyl (LPSQ-OH), methylglycolic (LPSQ-COOMe) and pentafluorophenyl (LPSQ-F5) moieties of different chemical properties were designed to modify PLA blends with PMMA. The effect of the type of LPSQ-R and their content, 1–3 wt.%, on the structure of the blends was studied with scanning electron microscopy (SEM) combined with energy dispersive spectroscopy (SEM-EDS), dynamic mechanical thermal analysis (DMTA) and Raman spectroscopy. Differential scanning calorimetry (DSC) and tensile tests also showed various effects of LPSQ-R on the thermal and mechanical properties of the blends. Depth-sensing indentation was used to resolve spatially the micro- and nano-scale mechanical properties (hardness and elastic behaviour) of the blends. The results showed clearly that LPSQ-R modulate the structure and properties of the blends.
