Study of atmospheric ice adhesion properties of superhydrophobic surface by in-situ shear system

Abstract

Based on shear strength calculation, this paper established an accurate method to measure the ice adhesion strength on any solid surface in an environment chamber by using self-made experimental equipment. The inherent characteristics of material and external environment which have strong influence on ice adhesion strength were investigated. The mechanism of ice adhesion was interpreted by studying the adhesion strength of ice layer with different surface wettability. The smooth steel substrate without any treatment and superhydrophobic surface samples were selected to study the relationship between ice adhesion strength and surface temperature. Meanwhile, the ice peak adhesion strength of the surface after freezing for 20–360 min under different low temperatures was analyzed. The results showed that the equipment provides a scientific and reasonable approach for the researchers to characterize the anti-icing performance of surfaces with different wettability.
