【摘要】：采用明胶为原料,以甲基丙烯酸缩水甘油酯和亚硫酸氢钠为改性剂,在明胶分子链上引入极性基团磺酸基,制得新型磺化明胶水凝胶。采用红外光谱(FT-IR)、X射线光电子能谱(XPS)和扫描电镜(SEM)对其组成和结构进行了表征。通过动态黏弹谱仪(DMA)测定水凝胶的储能模量,探讨不同外加电场作用下该水凝胶的电场响应性能。随着明胶水凝胶中S元素的原子百分比的增大,在外加电场下,胶体的电场响应能力增强。当外加电场为1.6kV/mm、明胶水凝胶中S的原子百分比为1.59%时,水凝胶对电场作用的响应最明显,储能模量的增加率为31.86%。

The composition and structure were characterized by infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM). The storage modulus of the hydrogel was measured by dynamic Viscoelastic spectrometer (DMA), and the electric field response performance of the hydrogel under different applied electric fields was discussed. With the increase of the atomic percentage of S element in gelatin hydrogel, the electric field response ability of colloid increases under the applied electric field.
