Functional groups are required at material surfaces, when chemical bonds should be achieved. Textile and fibers need functional groups e.g. for lamination, coloration, coating as well as for fiber-reinforced composites and tissue engineering (Fig. 1).
At Empa both wet-chemical and plasma-assisted activations are performed. Functional groups are directly applied to the material surfaces. Aging effects are minimized by the deposition of nanoscaled coatings with a high density of functional groups (Fig. 2).
The further development of conventional, wet-chemical treatments and the research on dry plasma processes to demonstrate the applicability for textile materials enable novel functional fibers and textiles using environmentally sound processes.
Long-term stable hydrophilization
Monolayer or nanoscaled coatings requiring low use of chemicals
Homogeneous or selective treatments
