Abstract
Electrochemical adsorption of polyvinyl alcohol (PVA) from sulfuric ac id solutions is studied. It is shown that the maximum coverage of the surface by the adsorbed polymer occurs at E = 0.3 V (NHE) and amounts to 0.6-0.65 monolayers at the highest PVA concentration. Desorption of PVA from the platinum surface starts from 1.1 V. It is assumed that a PVA unit occupies six adsorption centers, two of which are blocked be cause of steric hindrances.
