Kinetic study of surfactant binding into polymer gel - experimental and theoretical analyses
Article Abstract:
The kinetics of cationic surfactant binding into polymer were investigated using theoretical and experimental calculations. Cationic surfactant uptake into an anionic polymer network was analyzed using surfactants with various alkyl chain lengths changing ionic strength. The rate of the surfactant uptake was shown to be dependent on the surfactant alkyl size and ionic strength and was explained in terms of two factors. These factors are surfactant diffusion process and binding process.

Investigation of molecular diffusion in hydrogel by electronic speckle pattern interferometry
Article Abstract:
Experiments were performed on a series of surfactants and on myoglobin diffusion in agarose gels to investigate the diffusion process of surfactants and proteins in gels. The new electronic speckle pattern interferometry (ESPI) technique was used to examine the diffusion process. The ESPI values were found to agree well with electrical measurements and reported data. Results also showed a slight shrinkage of the agarose gel in surfactant solution.
