This dataset includes:1- All the data collected during liquid-liquid displacement experiments and all the corresponding analysis. This experiment was performed by pushing water at high flux values in 5 different cycles and measuring the pressure simultaneously.2- Fitting of LLDP results to the interfacial pore flow model.3- Microfluidic experimental observations in a microfluidic chip mimicking the porous membrane using laser scanning confocal microscopy and all the analysis using MATLAB.4- The Buckly-Leverett analysis of the shock front movement obtained from the microfluidic observations (using Matlab reservoir Simulation ToolBox (MRST)).5- Water contact angle measurement of dry, liquid-infused and dense PVDF membranes.6- Pore size distribution measurements of the pristine membrane.7- The results of surface tension values of all the infusion liquids and the corresponding interfacial tension measurements with water.8- The viscosity measurement results of all the infusion liquids.
