The aim of this work is to understand the influence of silica nanoparticles on the physical transitions of different polymer matrix : polyfurfuryl alcohol (PFA), polydimethylsiloxane (PDMS) and polytetrafluoroethylene (PTFE). Thus, the conventionnal thermal analysis techniques (TGA, DSC, DMTA) were employed in correlation with atypical...

Polytetrafluoroethylene (PTFE) is a polymer that displays exceptional properties. This synthetic fluoropolymer is also known to crystallize very fast upon cooling. The present work highlights for the first time the influence of nanosilica clusters on PTFE crystallization at fast cooling rates (up to 5000 Ks(-1)). The silica was synthesized from...

Fast scanning calorimetry (FSC) was employed to analyze the crystallization kinetics of poly(butylene succinate) (PBS) graphene nanocomposites. The emphasis of the present study is the heterogeneous nucleation of the PBS crystals in the presence of graphene nanosheets. Graphene oxide nanosheets were first synthesized and then reduced and...

Nanocomposite materials present attractive properties and are widely employed in various applications. Most of the time, the insertion of nanoparticles in a polymer matrix induces an enhancement of its performances, yet the effect of the filler on the polymerization mechanisms and the glass transition is less often investigated. In the present...
