Abstract
KMnO4-treated functionalized biaxially oriented polypropylene (BOPP) films coated with a hybrid material were synthesized, and the abrasion resistance properties of the resultant films were examined. The presence of functional groups was confirmed using Fourier-transform infrared spectroscopy, transmittance measurements were performed using an ultraviolet–visible spectrophotometer, and the intensities of the films were measured using a universal testing machine. The abrasion resistance and roughness of the composite films were significantly affected by modification of the BOPP film. The transmittance of the modified films obviously improved with the addition of Al2O3 sol, and the mechanical properties of the treated films were improved by the coatings. The abrasion resistance of one of the functionalized films (sample S159) increased by 79.5 % compared with that of the original film.
