Abstract
Measurements are presented of forces between two cellulose spheres in both air and aqueous solution. Forces in air are interpreted in terms of a dispersion interaction between two surfaces achieving poor mechan ical contact, while the forces in aqueous solution are well described by a double-layer interaction. No evidence for a steric interaction be tween the surfaces was discovered, in contrast to earlier work on rela ted systems. The technique is proposed as an ideal one for modelling i nteractions in papermaking and pumping systems.
