The hydrophobic surface-modification of lime powder by silane coupling agent, octadecyl trichlorosilane (ODTCS), at room temperature is introduced.

Ideal models of the non-smooth hydrophobic surface of typical plants;

Results show that the contact angle with water of surface exceeds 120°;the surface is formed by both PTFE coating and micro topography,and exhibits better hydrophobicity;part of hydrophobic surfaces has better effect in the experiments of drag reduction;the effect of drag.

This paper analyses some situations that vapor forms condensate while being cooled and forms frost on different surfaces,and studies several cases while the condensate breaks away from these surfaces,then discusss the probability of hydrophobic surface for preventing frosting and speeding defrosting in energy conservation.

Surface hydrophobicity index 94.

The protein structure has been characterized independently by free sulfhydryl groups content and surface hydrophobicity.

The effect on surface hydrophobicity and emulsifying properties was investigated.

Four kinds of soy protein was modified by Transglutaminase, surface hydrophobicity of protein was measured under different conditions, and single factor and orthogonal experiments was determined.

In this paper, the development of the theories of hydrophobic surfaces is briefly introduced, for example, the Wenzel rough surface model and Cassie-Baxter complex contact idea.
