The data corresponds to the published paper (on the gating mechanism of slippery liquid-infused porous membranes) which is the second chapter of my PhD thesis. The data contains following:1- All the gas-liquid porometry results of liquid-infused membranes made with different oils.2- Analysis of the aforementioned results and liquid film thickness calculation using annular two phase flow models.3- Results showing the re-infusion time and washburn analysis4- Water contact angle measurements results (static and advancing-receding CA)5- Pore size distribution results of the membrane6- An example of a Matlab file used for obtaining tikz files in order to plot the final graphs in Latex.
