Relationship between water structure and the thermal gelation propertiesof Hydroxypropyl methylcellulose (HPMC) in the presence of salts

摘要

Direct measurements of hydrogen bonding inwater, suggest that anions may alter the sol:geltransition temperature of HPMC, through their abilityto restructure water. This mechanism may underliethe observation that thermal gelation effects oftenfollow the Hofmeister series.
