| 摘要 |
The invention is directed to a golf ball providing improved UV resistance, abrasion resistance and hydrophobicity comprising cerium oxide nanoparticles having a particle size within the wavelength of visible light. The golf ball of the invention may comprise the cerium oxide nanoparticles in any or all of outer core layers, intemiediate layers, inner cover layers, outer cover layers and even as a coating composition in an amount of from about 0.5 wt % to about 10 wt % of the respective layer. The cerium oxide nanoparticles may be randomly dispersed within a layer or coating, or alternatively, the cerium oxide nanoparticles may be ordered in an array within the layer or coating.
