HYDRATION AND PHASE SEPARATION OF TEMPERATURE-SENSITIVE WATER-SOLUBLE POLYMERS

摘要：

The molecular origin of temperature-sensitivity of poly(N-isopropylacrylamide) (PNIPAM) in water is theoretically studied on the basis of cooperative (de)hydration. The observed sharp collapse of a PNIPAM chain on heating above 32℃ and very flat LCST line (horizontal up to 20 wt%) are shown to be caused by the cooperative hydrogen bonds between water molecules and amide groups with cooperativity
