PREPARATION OF PH SENSITIVE HYDROGEL INVOLVING TIO2

摘要

PURPOSE: A manufacturing method of pH sensitive hydrogen including titanium oxide is provided to offer antibacterial effect and water purification effect to the hydrogen, and to improve mechanical strength. CONSTITUTION: A manufacturing method of pH sensitive hydrogen includes the following steps: manufacturing a hydrogen precursor mixture including a pH sensitive precursor or a pH sensitive precursor and a mixture of a polymer precursor, a cross-linking agent, and a solvent; mixing TiO2 and an initiator to the hydrogen precursor mixture; and manufacturing hydrogen of IPN structure by cross-linking and polymerizing the mixture. The whole composition includes the polymer cursor and the pH sensitive precursor of 5 ~ 60weight%, TiO2 of 0.2~5 weight%, and the initiator of 0.1~3 weight%. The polymer precursor is polyvinyl alcohol.
