  • Limited studies have shown effective ways to protect aramid fabrics from photodegradation. The purpose of this research is to find an effective and feasible method to improve the photostability of Nomex® aramid fabric. An inorganic titanium dioxide sol-gel is used as a UV-protective coating on the fabric surface. The effectiveness of the sol-gel coating in preventing photodegradation is determined by examining changes in mechanical properties, chemical composition, as well as surface morphology structure of the coating. Findings show that nano scale anatase titanium dioxide thin films were formed on the fabric surface and decreased the photodegradation rate of the Nomex® aramid fabric.
