Summary:This research studied the relationship between nano-particle orientation and wear resistance. Nano-particle orientations were tailored through flow-assisted spray technical and parallel, randomly distributed, and preferentially vertical configurations were achieved. Surface damage tests were managed using nano, micro and macro scale tests, including nanoscratching using nanoindeter, and, sand falling and Taber Abrasion following ASTM standards.Composites with aligned nano-particle orientations showed the best wear-resistance levels, displaying a 60% increase as compared to contrast polymer coatings. The transparency levels before and after surface damage were also studied systematically. These composites are applicable in products requiring mechanical durability and optical transparency.
