A method of improving adhesion of an adhesive is detailed in the present application. The method includes coupling a layer comprising molecular chains, for example by grafting polymer brushes, to a surface of an adhesive material to form an adhesion promoting layer thereon, wherein the adhesive material with the adhesion promoting layer forms an adhesive product. The method further includes contacting the adhesive product with a surface of a base material, wherein a portion of the molecular chains at distal end penetrates into the surface of the base material, thereby adhering the adhesive material to the base material. The interaction between the molecular chains and the surface of the base material may be selected from the group consisting of physical interlocking, van der Waals force, electrostatic interactions and friction.
