Abstract
An amorphous, optically transparent, colorless shape memory assisted self-healing coating for optical glassware applications that uses a combination of surface shape memory and self-healing properties to repair damaged sites on glass substrates when exposed to a thermal stimulus. The coating includes a miscible combination of a network polymer and a linear polymer having glass transition temperate between room temperature and about 40 degrees C. The coating can be used for corrective eyewear, for windshields and windows in automobiles and motorcycles, as well for as optical coatings wherever needed.
