Interfacial properties of polyacrylamide solutions
Surface tension of the polyacrylamide solution was measured as a function of the polyacrylamide concentration (0-1000 gm/m(3)) and temperature (10-60 degrees C). The static contact angles of the polyacrylamide solutions in the range of 0-1000 gm/m(3) were reported on the polyvinyl chloride and Teflon substrates. Surface tension, static contact angle, and spreading behavior of the polyacrylamide solutions in the presence of different concentrations of NaCl, CaCl2, and AlCl3, are discussed.
