| Summary: | Molecular dynamic simulations were used to investigate the wetting behavior of nanocrystalline cellulose allomorphs. Three 40ns independent MD simulations using CHARMM force field gave droplet profiles, whose contact angles were obtained with LBADSA plugin for ImageJ. Surface hydrophilicity was related to hydroxyl group availability for hydrogen bonding. Oxidation of C6 hydroxyl groups significantly boosts surface hydrophilicity, and even low levels of modification (~7%) leads to contact angles close to zero degrees. These data can be useful for biotechnological applications. |
