Alter Surface Chemistry
The ability to control and tailor surfaces with specific chemical functionalities is oftentimes critical for studying surface interactions of materials or improving interfacial, biological, and electronic properties for optimal material performance. Depending on the process gas and processing conditions used, plasma can alter the surface to be more hydrophilic or hydrophobic, or to introduce specific chemical functionalities to the surface without affecting the bulk material. This page provides brief summaries on the application of plasma treatment to alter surface chemistry.
