Surface Chemistry
Our firm, Surface Chemistry, offers a wide spectrum of options to modify the chemical and physical properties of surfaces. Here, Dr. Grünwald’s more than thirty years of experience provide a wealth of possibilities, particularly in the areas of plasma and thin film techniques (CVD, PVD, etching and surface modification processes), including:
Plasma-chemical reactions in the gas phase
- Discover desired reaction pathways
- Generate aggressive gas species for etching purposes
- Find and correctly prepare the right gas molecules for coating or pattern etching
- Recognize problematic reaction channels
- Avoid undesirable or even dangerous exhaust emissions
Plasma reactions on plastics, metals, and glass
- Plasma activation of plastics in production
- Using plasma to fine clean metals in production processes
- Anti-corrosion protection for glass during fine cleaning
- Roughening plastics or giving structure to plastics, metals, and non-metals (for production purposes)
Deposition of metal coatings
- Vapor deposition and sputtering of aluminum, sputtering of stainless steel in production
Apply highly stable and thick, non-metallic coats using plasma polymerization
- Apply anti-corrosion coats to aluminum in production
- Wischfest- und Wipe-resistant and scratch-resistant coatings on plastics, in particular polycarbonate (PC)
- Diffusion barrier coatings on plastic bottles in production
- Coatings with high or low refractive index
- Adhesive coatings
- Electrically conductive coatings
- Fouling resistant coatings
- Growth-promoting coatings
Wet application or vapor deposition of polymer coatings
- Adhesion-resistant coatings
- Friction-reducing coatings
- Easy-care coatings (= combination of the two preceding features) in production
Plasma reactors for gentle production of coatings with defined chemistry
Plasma reactors with high deposition rates
