Chitosan salt suspensions showed a typical ER response(Bingham flow behavior) upon the application of an electric field. However, chitosan phosphate suspension exhibited anexcelent shear yield stress compared with chitosan and chitosan ammonium salt suspensions. The diference in behavior resultsfrom the difference in the conductivity of the disperse phases for thechitosan, chitosan amonium salt and chitosan phosphate suspensions exhibited a linear dependence on the volume fraction ofparticles, and power law dependence on electric field with power indices of 1.18, 1.41 and 1.67 respectively. On the basis of theexperimental results, the newly synthesized chitosan salt suspensions were found to be an ER fluid. 한국키틴키토산학회 Electrorheological Effect of Chitosan Salts as the Dispersed Phases Article 2 Journal of Chitin and Chitosan, v.11, no.3, pp.139 - 142 Journal of Chitin and Chitosan 11 3 139 142 N kci other ART001031964 chitosan salts ER effect bingham flow ER fluid chitosan salts ER effect bingham flow ER fluid
