Abstract

In the pervious paper, the plasma graft polymerization onto PET surface has been reported. In this paper, the resulting surface characteristic was investigated. The acrylic acid grafts were converted to the corresponding sodium salts by treatment with sodium carbonate. The sodium content of the grafts was determined to be around 318 ppd-1148 ppd by atomic absorption analysis. The soium salts of the grafts were highly hydrophilic as measured by wettability and antistatic properties. After dyeing with a basic dye, the color difference value determined by computer color matching(CCM) system and UV-visible spectrophotometer. The dyeability was markedly increased. It largely depended on the carboxylic acid content of the grafts. It was also verified that there was no change in wettability on aging by contact angle measurement.
