実験手順

Preparation of Comparative Example 2a (chitosan-pyrithione complex): a chitosan slurry was prepared by stirring 1 g VNS-461 into 50 g DI water. A solution of pyrithione acid (PA) was prepared in a separate flask by mixing 2.61 g 40% sodium pyrithione (NAP) solution obtained as sodium Omadine ("Omadine" is a trademark of Olin Corp, Cheshire, Conn.), with 22.4 g DI water and stirring followed by 25.28 g 1% hydrochloric acid. By this method, 99% of the NaP is acidified. The PA solution was added to the chitosan slurry, the mixture stirred 30 minutes, and the chitosan-pyrithione complex was filtered. This process was repeated four more times to yield five filter cakes of chitosan-pyrithione complex.
