The surface of all solid materials can be modified. RISE uses the method for cleaning of surfaces, increased adhesion to paints, lacquers and adhesives, preparation of liquid-repellent and biocompatible surfaces.
This is a service within the test bed “Surface analysis and Surface design” at RISE
Advantages
Plasma surface modifications have several important advantages compared with traditional wet chemical methods. Only the uttermost part of the surface is treated/coated without affecting the bulk properties of the treated material and extremely small amounts of chemicals are required. This leads to reduced need for chemicals, reduced impact on environment, improved work environment and lowered production costs.
What is plasma?
Plasma is referred to the fourth state of matter, ionized gas. It consists of electrons, ions, free radicals, various neutral molecules and photons. Low temperature plasmas can be created in several ways, but the most common way is the creation of a glow discharge by electric breakdown of gases. A low temperature plasma process, also referred to as cold plasma or glow discharge plasma, is in general a vacuum process which utilizes interactions of reactive species created in a low temperature plasma with solid surfaces. The interactions have unique features for surface modification of solids. The plasma processes are sometimes classified into Plasma Treatment (or plasma activation) and Plasma Polymerization (or plasma film deposition), depending on what type of gas or vapor is used and whether the interactions end up with deposition of a thin film or not.
Depending on choice of process gas or monomer (precursor), plasma surface modifications have found several different functions and applications. Some examples:
At RISE we work closely with our customers in research projects or in direct assignments. We usually use plasma surface modifications to:
What we can do for you
We at RISE can help you to evaluate different types of plasma surface modifications for your own applications. Our plasma lab contains several different types of plasma reactors, both for treatment/coating in vacuum and at ambient pressure. Our laboratory resources are at your disposal and we perform treatments/coatings, testing, verification, research and development. In addition, we also have access to a large instrument park with several advanced surface analytical instruments to characterize the modified surfaces and confirm the surface modification has given the desired result. The customer will receive a written report upon completed work.
