FTIR absorption spectra of the synthesized sols, coat- ings, and films were obtained using a Nicolet 550 spectrometer. The synthesized ZrO2 sol was dropped onto a KBr disk and dried in vacuum. For the cured sample, the coating sol was dropped onto a KBr disk, pre-baked at 80C, then UV-cured, and post-baked at 100C. For all scans, the spectra were collected over the wavenumber range of 400–4000 cm1 with a resolution of 4 cm1. Solid-state 29Si-NMR spectra of the cured coatings were recorded on a Bruker DSX400 WB spectrometer at 79.49 MHz. The chemical shifts were expressed in ppm with respect to tetramethylsilane. The size of ZrO2 particles suspended in the sol was deter- mined by dynamic light scattering (DLS), using a Zetasizer (Malvern, DTS 3000HS) at 25C at the concentration of 0.5 wt%. Morphology of the cured films was observed using a Leo 1530 field emission scanning electron microscope (FE-SEM). The samples werevacuum-driedandthenfracturedinliquidnitrogen to expose the cross section. Tape test (ASTM D3359), also called peel test, was carried out to evaluate the adhesion strength of cured coatings on the PMMA substrate. The degree of adhesion was recorded as the percentage of the residual film on the substrate after peeling by standard tapes (3M-610). The hardness (ASTM D3363) of the cured coatings was examined by the widely used pencil hardness test, using pencils of different hardness. The surface electric resistivity (ASTM D257) of the cured antistatic film was measured usingaHIOKISM-8200megohmmeterandanSM-8310 plate electrode at 1 kV and 60 s electrification time.
