Abstract
Polymer Nanocomposites have existed for decades now with different type of additives present in the polymer. The effect of properties depends on the scale of fillers. Nanofillers have increased within the years from nanoclays to carbon nanoparticles as well as the matrix in which they are used. The development of polymer nanocomposites is becoming more active in the area of nanomaterial because of their unique properties including optical, electrical, mechanical, thermal as well as fire retardant properties. These properties strongly depend on the mixing ratio between the organic matrix and nanofillers. Fullerenes have shown interest in the field of research due to unique chemical and physical properties that have been utilized in different fields of application in nanotechnology. The core was to focus on the mass weight of buckyballs fullerene C60 properties in polyurethane (PUR) and polyvinyl alcohol (PVA) polymer matrices to form stable polymer nanocomposites by using needleless electrospinning Nanospider? technology and rod electrospinning that would be applicable for flame retardancy material and anti-micro bacterial materials. The presence of fullerenes in polymers was investigated by thermogravimetric analysis (TGA), scanning electron microscope (SEM), Energy dispersive X-ray spectroscopy (EDS) and Raman spectroscopy. TGA results showed that the presence of C60 could enhance the thermal stability of organic polymers since organic polymers are inherently flammable. The larger the C60 level present, the better the flame retardancy of nanocomposites. Fullerenes are becoming good candidate as highly effective flame retardancy for polymeric materials by enhancing the flame retardancy properties.
