The surface friction of three kinds of gellan gels, non-purified gellan gel, Ca 2+ form gellan gel, and Na + form gellan gel, has been investigated against a glass substrate in water and NaCl aqueous solution. The non-purified gellan gels exhibit the lowest friction in pure water, especially at a low sliding velocity, showing a frictional coefficient of 0.001. The frictional stresses...
The friction between two chemically cross-linked polyelectrolyte gels carrying the same sign of charges has been investigated in pure water as well as in salt solutions. The friction was largely dependent on the charge densities of the gel surface and the ionic strength of the aqueous solution. The friction is described in terms of the hydrodynamic lubrication of the solvent layer between the two...
