Novel Mechanically Stable, Heat Resistant and Nonflammable Functionalized Polystyrene/Expanded Graphite Nanocomposites

Functionalized Graphene Nanocomposites

Expandable graphite/polyamide-6 nanocomposites

Polyamide-6 (PA-6)/graphite nanocomposites were prepared by melt blending, using a variety of graphites, including virgin graphite, expandable graphites and expanded graphite. The resulting nanocomposites were characterized by X-ray diffraction, thermogravimetric analysis, cone calorimetry, and tensile mechanical analysis. Nanocomposite formation does occur, as denoted by the nanometre dispersi...

Dielectric Properties of Graphite Nanocomposites

Stimuli-responsive mechanically adaptive polymer nanocomposites.

A new series of biomimetic stimuli-responsive nanocomposites, which change their mechanical properties upon exposure to physiological conditions, was prepared and investigated. The materials were produced by introducing percolating networks of cellulose nanofibers or "whiskers" derived from tunicates into poly(vinyl acetate) (PVAc), poly(butyl methacrylate) (PBMA), and blends of these polymers,...

Mechanically Responding Functionalized Polyelectrolyte Multilayer Films

The alternate deposition of polyanions and polycations on charged surfaces leads to the formation of nanostructured films called polyelectrolyte multilayers [1,2,3]. The layer by layer deposition process of polyelectrolytes is used to design films equipped by compartments containing "free" polymers or biomolecules [4-6]. Each compartment corresponds to a stratum of an exponentially growing poly...
