Review - Characterization of modified Elastomer Surfaces by wetting

摘要

This article features the current state of research with respect to plasma and varnished elastomer composites, which have been characterized by the sessile drop and the modified Wilhelmy balance technique. The sessile drop measurement is well suited to assess smooth and plasma modified surfaces of elastomers qualitatively. However, rough samples should be analyzed by other methods such as modified Wilhelmy balance technique having several advantages compared to the sessile drop method, e.g. high accuracy and reproducibility. It is shown that contact angle hysteresis values correlate well with roughness parameters that are obtained by white light interferometry.
