Capillary condensation of moisture in fractal pores of native cellulose powders

This study was performed to investigate the applicability of the theory of capillary condensation of moisture in fractal nanopores of native cellulose powders of various origins. The characteristic fractal dimensions D were calculated and their physical meaning discussed. The method proved useful for obtaining versatile information about the water–cellulose interactions as well as the bulk structure of cellulose particles.
