Abstract: Ice formation and frost accumulation on applications such as the surfaces of aircrafts, refrigerators, power lines, turbines etcetera have long caused problems and inconvenience in today’s world. Current and constant researches have been undergone to rectify or improve this problem. The more popular methods of date for anti-icing applications are the usage of superhydrophobic surfaces and Slippery Liquid-Infused Porous Surfaces (SLIPS). Although there has been intensive research for the reduction of ice formation on surfaces, little has been done or known about the velocity of freezing propagation of ice on different wettability or morphology of surfaces. Apart from understanding the influence of ice nucleation and de-icing properties on various wettability and roughness of surfaces, further investigation on the velocity of freezing propagation of ice on the various surfaces has been carried out. By understanding the freezing propagation performance of ice on different types of surfaces, we can not only reduce the chance of ice nucleation, but also retard the propagation of ice across surfaces such that it may not only allow an application to function longer, but also provide more time for rectification to be carried out on the application. Therefore, in this project, 4 main different types of substrates with varied surface properties (wettability and roughness) are chosen to be experimented on such that a more in-depth analysis can be obtained from the results to understand the relationship between the various surfaces and ice nucleation, velocity of freezing propagation and de-icing properties of condensates on those surfaces.
