| 中文摘要 | counterions present at the surface of polyelectrolyte multilayers (pems) were utilized for modulation of surface wettability via ion exchange. the pem film was dipped in aqueous solutions of different anions, respectively, and the water contact angle of the surface varied from about 10 degrees to 120 degrees, depending on the hydration characteristics of the anion. the ion exchange mechanism was verified by x-ray photoelectron spectroscopy. the process was rapid and reversible. ionic strength of the polyelectrolyte solution used for preparing the pems was found to be crucial to the surface wetting properties and the reversibility and kinetics of the process, and the effects were correlated to the surface density of the excess charge and counterion. this work provides a general, facile and rapid approach of surface property modulation. |
