Development of nanocomposite with LDPE and Graphene nanoparticles by means of melt extrusion method

Abstract

Graphene nanoparticles have found an important role in the field of nano composites as a potential filler material through enhancement of the matrix property. In the present study graphene nanoparticles in varying amounts are mixed with low density polyethylene, the most extensively used polyolefin using melt extrusion method. This manufacturing process imposes strong anisotropy on the sample’s morphology where the filler particles are oriented along the extrusion direction. The nano composite prepared was found to exhibit excellent thermal withstanding behaviour. The Differential Scanning Calorimetry (DSC) study results had shown that as the amount of filler is varied, the thermal properties material is found to be enhanced compared with the virgin polymer. The absorption properties of the composite were verified using UV visible photometer. As the amount of graphene nanoparticles is increased the intensity of absorption of the composite is also found to be increased. Developed material with enhanced thermal stability can find applications in electric and electronic devices specifically in biomedical field where soft and flexible material are required.
