Abstract
We have studied the surface activity of polyethyleneoxide (PEO) by mea suring the reduction of the surface tension of an aqueous solution. Th e surface adsorption of PEO is strongly dependent on the polymer molec ular weight and the concentration. These findings are confirmed with t he results of the ellipsometry measurement which provides the total ad sorbed amount of the polymer. Furthermore, the changes of surface wave s due to the adsorbed layers is detected by surface wave spectroscopy. (C) 1997 Elsevier Science B.V.
