摘要/Abstract

摘要： 通过化学反应将甲基丙烯酸二甲氨基乙酯(DMAEMA)接入壳聚糖(CTS)的分子结构中,获得改性产物CTS-g-DMAEMA。使用红外光谱和核磁氢谱对其进行了结构表征。向CTS-g-DMAEMA的聚集体分散液中依次通入CO₂和N₂后,其外观形态、透光率和电导率发生了明显的循环变化,证实了CTS-g-DMAEMA的CO₂/N₂刺激响应性。水-液体石蜡的乳化实验证明,与原料CTS相比,CTS-g-DMAEMA具有更好的稳定乳液的能力;并且在CO₂/N₂作用下,由CTS-g-DMAEMA制备的乳液可以发生破乳和再乳化的循环。

Abstract: 2-(Dimethylamino) ethyl methacrylate (DMAEMA) was grafted onto the molecular structure of chitosan by chemical reaction.FT-IR and ¹H NMR were used to characterize the structure of the modified product (CTS-g-DMAEMA).The appearance,conductivity and transmittance of the dispersion of CTS-g-DMAEMA aggregates are repeatedly changed in the stimulation of CO₂ and N₂,which shows the CO₂/N₂-switchable behavior of CTS-g-DMAEMA.The emulsification experiment of water-liquid paraffin illustrates that the CTS-g-DMAEMA shows better emulsification capability than the raw chitosan.Moreover,under the action of CO₂/N₂,the emulsion prepared by CTS-g-DMAEMA can be demulsified and re-emulsified circularly.

Key words: chitosan, 2-(dimethylamino) ethyl methacrylate, grafting modification, CO₂/N₂-switchable emulsifier
