New Method to Produce Transparent, Fluorine-Free, Anti-Smudge Polyurethane Coatings
Self-cleaning windows, stain-resistant automobile interiors, graffiti-proof walls — there is a long list of things that we wish could have a surface to which dirt wouldn’t stick. In the journal Angewandte Chemie, Canadian scientists have now introduced a new method for producing transparent, smudge-resistant coatings resistant to both water- and oil-soluble contaminants. In contrast to previous approaches, this method does not use fluorinated substances, which makes the coatings both significantly less expensive and more environmentally friendly.
