Abstract:
Nanocomposites represent an interesting class of materials because their applications are of multidisciplinary importance. Interactions at the interface of heterostructures, are leading to superior performance and sometimes to synergistic interactions. Graphene-based materials are among the most intriguing materials for researchers in recent times due to their exotic properties which find applications in various domains right from sensors to textiles, pharmaceuticals, intelligent coatings and biomedical applications. When such materials are incorporated in polymer matrices to form either composites or doped-polymers or simply carbon-reinforced-polymers, their applications broadens encompassing aerospace structures, sports equipments, auto vehicle parts, organic solar panels, supercapacitors, smart sensors, intelligent paints, electromagnetic interference shielding (EMS) and so on. Novel graphene and titanium dioxide- polyvinylidene fluoride (PVDF) based nanocomposite materials (G-TiO2-PVDF) fabricated by electrospinning technique and their properties will be presented. The new composite materials show enhanced properties that make them candidates for large range of applications such as antibacterial membranes or electromagnetic radiation shielding. PVDF is used in critical applications requiring an excellent chemical resistance, a high degree of purity and excellent mechanical properties. PVDF has a very good creep resistance that is superior to that of other fluoropolymers, it is UV resistant and has a high dielectric constant.
