Research output: Contribution to journalArticlepeer-review


Understanding cellulose-water interactions is important for advancing current technology, not the least in developing effective dissolution methods for wooden fibers. Here we study the effect of electronic polarization on cellulose-water interactions by all-atom computer simulations. We show that induced dipoles on both interfacial water and cellulose hydroxyl groups are significant and may influence cellulose/co-solute interactions. The non-polarizable SPC/E water model yields remarkably similar solvent radial distribution functions as the polarizable POL3 model while orientational correlations differ slightly. For the present study we have developed a polarizable cellulose force field, based on the popular GLYCAM parameters, as well as tested the Wolf technique for handling long range dipolar interactions in polarizable, all-atom Monte Carlo simulations.
