成功制备了一系列不同环硅氧烷含量的硅橡胶样品，并对其疏水恢复行为和机理进行了详细的研究。利用索氏萃取后的气相色谱-质谱技术检测样品中的低分子量硅氧烷，利用扫描电镜观察等离子体处理对硅橡胶表面形貌的影响，利用接触角测量探测不同储存温度下等离子体处理后样品表面的疏水回收率。用菲克第二定律计算的扩散模型可以很好地拟合水的贮存时间接触角。结果表明，硅橡胶的疏水恢复与低分子量硅氧烷的扩散有关，而更大的含量或更高的温度可以诱导更快的疏水恢复。
A series of silicone rubber samples with different cyclosiloxanes contents have been successfully prepared, and their hydrophobic recovery behaviors and mechanism were investigated in detail. The gas chromatography-mass spectroscopy technique after Soxhlet extraction was utilized to examine the low molecular weight siloxanes in the sample, SEM was used to observe the surface morphology of the silicone rubber influenced by plasma treatment, and contact angle measurement was applied to probe the hydrophobic recovery of the sample surface after plasma treatment at different storage temperatures. The storage time-dependent contact angle of water can be well fitted by the diffusion model calculated from Fick’s second law. The results imply that the hydrophobic recovery of silicone rubber is related to the diffusion of low molecular weight siloxanes, while larger content or higher temperature can induce faster hydrophobic recovery.
