| Abstract: | Polyacetylene films have been rendered hydrophilic by treatment with aqueous KMnO4. The treated films were characterized by contact angle measurement, infrared spectroscopy, and x-ray photoelectron spectroscopy. We found that it is possible to lower the contact angle of H2O on polyacetylene from 72° to ca. 10° without significantly affecting the electrical conductivity afforded after I2 doping compared with similar doping of untreated films. The treated, hydrophilic films were found to be more permeable to aqueous ionic solutions than pristine polyacetylene. |
