Particle Assisted Wetting

本项目的目标是对颗粒辅助润湿有一个完整的了解。我们建议系统地改变颗粒的形状、大小和表面涂层；选择一组非水溶性液体，测量液体/水/颗粒、液体/空气/颗粒和水/空气/颗粒的接触角。同时，我们将这些颗粒与有机液体的混合物应用到水面上，并确定混合物是否会以均匀的层扩散，液体是否会形成透镜。混合物的这种行为将与所确定的接触角和颗粒与液体之间的体积比相关联。

The goal of the current project is to obtain a complete understanding of particle assisted wetting. We propose here to systematically vary the shape, size and surface coating of paticles; select a set of non water soluble liquids and measure the contact angles liquid/water/particle, liquid/air/particle and water/air/particle. At the same time we apply mixtures of these particles with the organic liquids to a water surface and determine whether the mixture will spread as an even layer of whether the liquid will form lenses. This behaviour of the mixture will be correlated with the determined contact angles and the volume ratio between particles and liquid.
