The retardation of aging of oxygen plasma-treated polypropylene |
| 초록 |
Plasma-treated polypropylene has been characterized both before and after plasma treatment. The crystallinity of untreated polypropylene has been determined using differential scanning calorimetry and wide angle X-ray scattering. The chemical properties of plasma-treated polypropylene surface have been investigated by X-ray photoemission spectroscopy and contact angle measurements. The morphology of oxygen plasma-treated polypropylene surface is studied using SEM. The degree of cross-linking on the surface has been estimated by gel content measurements. The polymeric surface was altered by introducing polar hydrophilic group through the plasma treatment and the modified surface was reconstructed by aging. XPS and contact angle measurements have indicated that the aging effect was lowered on increasing the crystallinity the sample. This is due to the decrease in mobility of the polymeric chains caused by an increased crystalline order on the surface. Similar effects have been observed by enhancing the degree of cross-linking at the surface. |
