Abstract

The cooperation of solute and solvent is taken as the gelation condition. The three dimensional percolation of blobs is taken as the gelation model. Phase transition of polyelectrolyte solution is then considered as a process of the formation and the percolation of blobs. By the study of the gelation of different concentration of alginate solutions induced by calcium cation, the nature of sol-gel transition has been suggested. Critical exponent of relative viscosity near the gelation point was determined as κ=0.90∼0.97. A power-law relation was confirmed between the gelation point ∫_c and alginate concentration c. In addition, the correct range of application of the power-law relation of relative viscosity near gelation point, η_rel ∝ (∫_c - ∫)^-κ, has also been defined.
