Molecular dynamics simulation of membrane in room temperature ionic liquids

The polyvinylidene difluoride (PVDF) membrane has been a popular material in membrane separation process. In this work, molecular dynamic simulation was done on the PVDF membrane with 100 wt IL and 50 wt IL in GROningen MAchine for Chemical Simulations (GROMACS). The results was evaluated based on p...
