Abstract

<p>The photochemical surface modification of a silicone-based thermosetting hard protective film was achieved by using an excimer lamp with wavelength of 172nm. As the result of Taber abrasion test, ΔHaze value was 1.3%, almost the same as a generally used glass. Surface hardness measured by nanoindentation was more than 2 GPa, showing a great improvement with respect to 0.7 GPa of the original hard-coat. It was revealed that the SiO2 layer was dominantly formed on the surface of the hard-coat layer, by using fourier transform spectroscopy and photoelectron spectroscopy.</p>
