Oxidized Fullerene (OF) nanoparticles were added to the hybrid sol-gel coating at different concentrations (0–500 mg L⁻¹). Improvement in the surface morphology of the coatings via incorporation of low and moderate concentrations (25–100 mg L⁻¹) of the OF nanoparticles was shown by the SEM. Also, chemical interaction of the nanoparticles with the coating was confirmed by the FTIR and Raman spectrums. Size and dispersion of the OF nanoparticles in the sol-gel film and corresponding sol solution were determined by the TEM and DLS, respectively. The AFM images showed that the surface roughness of the silica film reduced from 67.5 to 62.8, 56.1, and 40.3 nm by inclusion of 25, 50, and 100 mg L⁻¹ of the nanoparticles, respectively which was ascribed to the interaction of the OF nanoparticles with the coating. Significant enhancement in the corrosion resistance of the neat silica film by incorporation of the OF nanoparticles was confirmed by the EIS experiments in 3.5 wt% NaCl solution which was ascribed to the removal of defects as a result of the chemical interaction. However, the positive effects of the OF nanoparticles on the corrosion resistance was reduced at higher concentrations.

氧化富勒烯（OF）的纳米粒子加入到在不同浓度（0-500毫克的L混合溶胶-凝胶涂层^{- 1}）。通过低和中等浓度（25-100毫克的L的掺入改善涂层的表面形态^{- 1}的纳米颗粒是由SEM示出）。同样，通过FTIR和拉曼光谱证实了纳米颗粒与涂层的化学相互作用。分别通过TEM和DLS确定OF纳米颗粒在溶胶-凝胶膜和相应的溶胶溶液中的尺寸和分散性。AFM图像表明二氧化硅膜的表面粗糙度从67.5减少到62.8，56.1，和通过包含25,50 40.3纳米，和100毫克的L ^{- 1}分别归因于OF纳米颗粒与涂层的相互作用。通过在3.5 wt％的NaCl溶液中进行EIS实验，证实了通过掺入OF纳米颗粒，二氧化硅净膜的耐蚀性显着提高，这归因于由于化学相互作用而导致的缺陷去除。然而，在更高的浓度下，OF纳米颗粒对耐腐蚀性的积极作用降低了。
