A composition is provided that includes a graphene dispersion, a silicone microemulsion, a reactive siloxane emulsion, and organic solvent as a majority by weight of the composition. A process for imparting a durable shine to a vehicle surface is also provided. The composition is applied to the vehicle surface. The water is allowed to evaporate from the composition to form a coating imparting a durable shine to the vehicle surface. A coating is obtained after evaporation. The coating includes a silicone film formed by the evaporation of water from a silicone microemulsion and the cross-linking of a siloxane from an emulsion. Graphene particles are embedded in the silicone film. The coating has a thickness of between having a thickness of between 5 and 10,000 nanometers and a hardness of between 3 and 7 GPa.

The present invention relates to an antireflection film. The antireflection film includes a low refractive index layer having excellent alkali resistance and exhibiting remarkably improved mechanical properties such as scratch resistance and impact resistance as well as reduction of a glare phenomenon, and a base film exhibiting excellent mechanical strength and water resistance in spite of a thin thickness and having no fear of interference fringes occurring. Therefore, such antireflection film can be used as a protective film of a polarizing plate or used as any other component so as to provide a thin display device, and furthermore, can effectively prevent the glare phenomenon of the display device, and can more improve the durability and lifespan thereof.
