摘要
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.关键词
