Abstract
A polymeric coating for a glass substrate includes a hexafluoropropylene oxide derived silane polymer. The hexafluoropropylene oxide derived silane polymer has a molecular weight of greater than about 5500, a thickness of between about 2 and about 15 nanometers and a coefficient of friction constant of less than about 0.35. A water contact angle of the polymeric hexafluoropropylene oxide derived silane coating decreases by less than about 27% after being subjected to 10000 abrasion cycles.
