Seeing touch screens get daubed with finger marks and other blemishes can be a heart-wrenching experience. Although screen overlays that help protect touch screen devices are easily available, scientists are trying to figure out ways to make touch screens more smudge resistant. They have developed a test for ascertaining the efficacy of anti-smudge – and reflection – coatings found on touch screens.
"Surfaces are particularly important in consumer products. This work investigates how products can be modified to reduce smudging and reflections. These modifications can offer improved resistance to fingerprints, anti-reflection properties or enhanced physical resistance,” Dr Stephen Carlo said while describing the test at the 238th National Meeting of the American Chemical Society.
Dr Carlo’s team used depth profile X-ray photoelectron spectroscopy (XPS) to compare the chemistry of anti-smudge and anti-reflective coatings. Their findings could lead to touch screens that are clearer and more immune to smudge.
