INFINITE CHANGES ON TOP
PLASMA TECHNOLOGY
Today Plasma technology offers a valid alternative to conventional chemistry in the process of surface finishing of materials, with many benefits due to its high eco-sustainability. Plasma chemistry is a “dry and green” chemistry working without solvents and with minimal use of reagents. It is based on the physical principle that by supplying energy to matter, changes in its state happen so that:
solids becomes liquid and liquids becomes gaseou
If energy is supplied to a gas, it is ionized and generates the PLASMA , called the fourth state of matter.
solid PLASMAETCHING
the ablation of materials through the formation of volatile products after interaction of the material with the active species produced in the plasma. This class of processes is most commonly used in microelectronics, for designing integrated circuits with high spatial resolution, by means of the anisotropic chemical attack on silicon. Furthermore these processes underlie the technologies of cleaning or sterilization.
PLASMAENHANCED CHEMICALVAPOUR DEPOSITION (PE-CVD) deposition of thin
liquid (5-1000 nm) organic or inorganic coatings, this is probably the widest class of plasma processes. PE-CVD processes can apply many different classes of coatings to tailor the surface of materials, with composition and properties that span from teflon-like to silicalike to nano-composite, from super hydrophobic to hydrophilic to hydrogel-like. It is possible to adjust at the best of the customer needs or applications the stability of the coating-material interface, a property that is crucial for uses like corrosion protection and functionalization of biomedical polymers.
This is an ionized gas rich of reactive species such as radicals, ions and electrons able to modify the surface properties of the materials exposed to it. It becomes possible to finely tune the surface properties of the materials through the fine adjustment of the experimental parameters, resulting in a customized “surface tailoring “ of materials, without affecting their bulk properties. Three main classes of plasma processes can be defined, namely:
Plasma Etching, Plasma Enhanced Chemical Vapour Deposition (PE-CVD), Plasma Treatment.

PLASMATREATMENT
That is grafting of functional groups on materials. Grafted functionalities may be partially associated with a certain degree of cross-linking of the treated surface. Plasma treatments are generally used to impart new surface properties on polymers, paper, textiles and other materials with negligible addition or subtraction of mass. Stable changes from hydrophobic to hydrophilic surfaces (and viceversa) are possible, and many others for uses like enhanced printing capability, dyeing, metallization, enhanced/reduced wettability, and many others.
