The aging characteristics of laser-treated superhydrophobic silicone rubber surfaces was investigated through accelerated aging tests. It indicated that the superhydrophobic surfaces have excellent anti-aging properties, which is manifested in that even after aging for 1000 h, the contact angles of the superhydrophobic surfaces remain above 140^o. The loss of hydrophobicity was caused by defects in the surface microstructures, a decrease in the hydrophobic ―CH₃ groups, and an increase in the hydrophilic ―OH groups on the surfaces. To avoid the decrease in the hydrophobicity of the prepared superhydrophobic surface, a simple and efficient heat treatment method was adopted to restore its hydrophobicity. After heat treatment at 200°C, the rolling angle of the aged surface was restored to 4.6^o with a contact angle of 161.5^o. This recovery is mainly attributed to the decrease in the content of the ―OH on the rubber surface during the heat treatment. The results also show the sample surface irradiated with a laser fluence of 10.0 J/cm² has better anti-aging performance and self-healing properties due to the larger particles and a more distinct micro-nano hierarchical structures, providing a smaller actual illumination area and a larger heating area in the aging and heat treatment process.

通过加速老化试验研究了激光处理的超疏水硅橡胶表面的老化特性。这表明超疏水表面具有优异的抗老化性能，这表现在即使老化 1000 h 后，超疏水表面的接触角仍保持在 140 ^o以上。疏水性的丧失是由表面微结构缺陷引起的，疏水性―CH ₃基团，以及表面亲水性 -OH 基团的增加。为避免制备的超疏水表面疏水性下降，采用简单有效的热处理方法恢复其疏水性。在200℃下热处理后，老化表面的滚动角恢复到4.6 ^ø与161.5的接触角^Ò。这种恢复主要归因于热处理过程中橡胶表面-OH含量的减少。结果还显示了用 10.0 J/cm ²的激光能量密度照射的样品表面 具有更好的抗老化性能和自愈性能，由于颗粒较大，微纳层次结构更加明显，在老化和热处理过程中提供更小的实际照射面积和更大的加热面积。
