The adhesion between graphene and polymer is important to prepare graphene-containing products such as composites, barriers and electronic devices. Poor adhesion leads to long term stability degradation of graphene based product, because water or other molecules exiting in air are easily adsorbed between the graphene surface and polymer. However, understanding the adhesion of graphene to other material is not simple due to the various influencing factors such as surface roughness, surface energy, graphene thickness and wettability. Here, we studied the relationship between surface free energy and adhesion force of graphene to common polymers. The surface free energy was calculated by contact angle measurement and relative adhesion force was inferenced by delaminating graphene sheets from Cu foil. This results can provide a clue for designing polymer materials with desired adhesion force to graphene surface. |
