What are the Common Methods for Surface Modification?
Several techniques are employed for surface modification in nanotechnology: 1. Chemical Vapor Deposition (CVD): This method involves the deposition of a thin film on the surface through chemical reactions in the vapor phase. 2. Physical Vapor Deposition (PVD): Similar to CVD, but involves physical processes like evaporation or sputtering. 3. Self-Assembled Monolayers (SAMs): SAMs are formed by the spontaneous organization of molecules on a substrate, creating a well-ordered layer. 4. Plasma Treatment: Involves the use of plasma to modify the surface chemistry, often used to increase surface energy and promote adhesion. 5. Grafting: This technique involves the covalent attachment of polymers or other molecules to the surface.
