摘要: The temperature/pH dual sensitivity reed hemicellulose-based hydrogels have been prepared through glow discharge electrolysis plasma (GDEP). effect of different voltages on the temperature and pH response performance was inspected, formation mechanism, deswelling behaviors were also discussed. At same time, infrared spectroscopy (FT-IR), scanning differential thermal analysis (DSC) electron microscope (SEM) adopted to characterize structure, phase transformation microstructure hydrogels. It turned out be that all had a double pH, their transition temperatures approximately 33 °C, as well dynamics met first model. In addition, hydrogel (TPRH-3), under voltage 600 V, more sensitive higher ratio.
