Fraunhofer Institute for Interfacial Engineering and Biotechnology IGBTechnological aspects of plasma treatment
- final cleaning, activation and coating in a single technological step
- three-dimensional substrates can be as well coated
Advantages of plasma technologies, and properties of plasma produced films
Chemical aspects of plasma treatment
- chemical diversity of film forming substances
- no polymerization aids necessary
- high cross-linking
- it is possible to produce special functional groups on the surface, e. g.
- hydroxyl
- amine
- aldehyd
- carboxyl
- grafting of larger molecules
Properties of plasma deposited films
- good adhesion can be achieved
- high homogeneity of film thickness and structure
- surface and film properties can be varied in a wide range
- films are pinhole-free at low thickness
Economical and ecological aspects of plasma treatment
- low costs for raw materials and low running costs
- low consumption of chemicals
- solvents free, dry process
- the used chemicals are kept in closed equipment
