| dc.description.abstract | In this study, the morphology and thermo-mechanical behavior of composites formed by a polyoxymethylene (POM)
matrix and monosilanolisobutyl polyhedral oligomeric silsesquioxane (msib-POSS) filler have been studied. The msib-
POSS molecules were added to the POM by direct melt blending at loadings between 0 and 10 wt.%. Hydrogen bonding
interactions were detected between POM and msib-POSS Si–OH groups, increasing their mutual compatibility and leading
to nanometer-size dispersion of some msib-POSS molecules. These interactions do not prevent POSS aggregation during
blending, but lead to micron-scale msib-POSS domains. The thermal decomposition temperature of the composites
remained practically constant under inert and oxidative conditions. The low temperature thermal transition (g) and glass
transition temperature (Tg) of POM were found to move to higher temperatures only when 2.5 wt.% of msib-POSS was
added, indicating that POSS is physically linked to the POM chains, restricting their motion under those conditions. Low
content (2.5 wt.%) of msib-POSS results in antiplastization, whereas higher levels of POSS lead to a decrease in the storage
modulus of the polymer. The relationships among these effects and the morphological characteristics of the systems will
be discussed herein |
