球形的 MgSO4 微滴被注射在恐水病的特氟隆重底层上扔。用 micro-Raman 技术,激光横梁高度集中于两次表面并且在球形的微滴的中心。为表面的拉曼系列并且 MgSO4 微滴内部因此被获得,在低相对湿度在 MgSO4 微滴上建议胶化的薄层的形成。胶化层盖住表面并且响应周围的相对湿度的变化展出了重要延期,导致表面之间的结构的差别并且 MgSO4 微滴内部。
Spherical MgSO4 droplets were deposited by a syringe on the hydrophobic Teflon substrate. Using micro-Raman technique, the laser beam was highly focused twice on the surface and in the center of spherlcel droplets. The Raman spectra for the surface and the inner of MgSO4 droplets were accordingly obtained, suggesting formation of a thin layer of gels on MgSO4 droplets at low relative humidity. The gel layer covered the surface and exhibited a significant delay in response to the change of amblent relative humidity, resulting in the structural difference between the surface and the inner of MgSO4 droplets.
