RELATIONSHIP BETWEEN THE PHYSICAL-PROPERTIES AND SURFACE-AREA OF CELLULOSE DERIVED FROM ADSORBATES OF VARIOUS MOLECULAR SIZES

An aqueous suspension of bacterial cellulose (BC) has such physical pr operties as higher viscosity, emulsion estabilizing effect and filler retention than cellulose of other origins. The specific surface areas of BC, microfibrillated cellulose and wood pulp were evaluated by dete rmining the maximum amounts of adsorption of Congo red, cellobiose deh ydrogenase (CDH) and xyloglucan. There was a positive linear correlati on between the above-mentioned physical properties of each cellulose s ample and the specific surface area derived from the maximum amount of CDH adsorbed. The highest physical property values for BC result from the largest external surface area of the fibrils of BC to which CDH w as adsorbed.
