| Popis: | Anti-icing properties were investigated in terms of adhesion force on slippery lubricant-infused porous surfaces with several lubricants. Initial wetting state of substrate and lubricant characteristics were verified in anti-icing performance. Superhydrophobicity of porous substrate under lubricant intervening layer was effective to reduce adhesion force in anti-icing. The relationships between adhesion force and lubricant characteristics including viscosity, density, and surface tension were analyzed but no correlation was found. Interfacial surface tension exhibited a relatively negative correlation with adhesion strength. However, spreading coefficient of liquid–liquid interface was found to be the most important factor in determining lubricant when designing icephobic surfaces. |
