2.About plasma treatment
3.various application of plasma technique
Commonly, radio-frequency (RF) at 13.56 MHz is used to create the glow discharge.
Typical pressures are between 1 mtorr and 5 torr.
Effective method for modifying surface property of a material little effect on bulk properties of the materials.
Rapid, clear, non-solvent surface modification method
Introduce some specific element or functional group onto the surface of materials.
Specific functional groups provide special chemical reactivity and varying physical properties for surface
A variety of molecules such as protein, peptide and gelatin, have been successfully bound on surface of materials.
Application : improvements
•The plasma method gives more enhanced strength to these ceramics as compare to conventional method
•Coating film of the uniform thickness
•more improvement of mechanical properties
