Effect of tacticity of poly(methyl methacrylate) on interfacial region with silica in polymer nanocomposite

The effect of tacticity on the interfacial region between poly(methyl methacrylate) (PMMA) and silica in a PMMA/silica nanocomposite was investigated by differential scanning calorimetry (DSC), Fourier‐transform infrared spectroscopy (FT‐IR), and X‐ray diffraction (XRD). The glass transition temperature ( T g ) values of the syndiotactic ( st ‐) and atactic ( at ‐) PMMA/silica nanocomposites are higher than those of the neat PMMA. Conversely,...
