Study on Interfacial Characteristics of Polyacrylamide Solutions
Sinopec Dongying · Chinese Journal of Colloid and Polymer · 2004
Using the TRACKER fully automated drop tensiometer to the interfacial rheology in dilatation or contraction of dodecane/polyacrylamide solutions,in different experimental conditions. A measurement of the interfacial visco-elastic modulus as a token of the membranes' intensity is founded. During the process of the dodecane/polyacrylamide interface balance, the interfacial visco-elastic modulus increases with increasing time and come to the equation. The elastic component is higher than the viscous component. The interfacial visco-elastic modulus increases with increasing concentration of the polyacrylamide. After aging of the polyacrylamide solutions, The interfacial visco-elastic modulus decreases.The interfacial tension does not chang with polyacrylamide concentration.
