Graft-copolymer-based approach to anti-smudge polyurethane coatings

Friday, 8 May 2015

Clear, durable anti-smudge coatings with a thickness of up to tens of micrometers have been prepared through a graft-copolymer-based approach from commercial precursors.

The coatings repel water, diiodomethane, hexadecane, ink, and an artificial fingerprint liquid.

In addition, they can be readily applied onto different substrates using different coating methods. These coatings could find applications in protecting hand-held electronic devices from fingerprints, windows from stains, and buildings from graffiti.

The study is published in: Angewandte Chemie.
