A literature review of poly(methyl methacrylate) (PMMA) nanocomposites
shows inconsistent results regarding the influence of the addition
of nanofillers on the mobility of the system. In academic research, solvent
based preparation methods are often used to prepare nanocomposites with
the aim to obtain a good and controlled dispersion. However, little attention is
paid to the influence of the used solvent on the properties of the
nanocomposites. We show that in PMMA nanocomposites prepared via
solution casting from different solvents, the apparent decrease in glass
transition temperature is caused by insufficient drying and that when an
adequate drying procedure is used, an increase in glass transition
temperature is always observed.
