Nanoporous LLC polymers are exciting materials for filtration applications as they possess uniform channels that allow permeation of solvent while blocking larger solutes. Q phases of LLCs are particularly attractive as the hydrophobic and hydrophilic channels are continuous in all directions eliminating the daunting task of aligning nanoscale channels. Furthermore, Q structures are found in biological systems and have several technical applications such as drug delivery, controlled chemical reactions, and nanofiltration. The tunability of the bilayer curvature in the Q phase is also exploited in designing cubosomes 80 intended for drug delivery applications. MD simulations can provide atomic level details which are necessary both to understand the function of these membranes and to design them for specific applications. However, modeling Q I structures at the atomic level is a challenge due to both the computational cost as well as the narrow range of stability which requires molecular models to be particularly accurate.
