The addition of graphene as filler or as a platform improves the physico-chemical and electrical properties of conventional polymer materials.
In addition it enables to attain a low percolation threshold at lower loading fractions compared to other carbon materials[4].
Therefore it uses less amount of conducting filler and cheaper in contrast to other carbon particle materials.
Methodology Reagents and Materials.
Biological and chemical sensors based on graphene materials.
