采用两步胶体模板聚合法再引入苯硼酸基团和刻蚀模板,制备了一种具有温度和葡萄糖双重刺激响应性的新型智能空心纳米水凝胶,用傅立叶变换红外光谱、核磁共振、透射电镜和动态激光光散射等手段对其进行了表征。结果表明,空心纳米水凝胶由聚(N-异丙基丙烯酰胺)和聚(N-苯硼酸基丙烯酰胺)组成,具有互穿聚合物网络结构和内部为空腔的形态结构,并具有葡萄糖和温度双重刺激响应性。
A new type of smart hollow nano-hydrogel with temperature and glucose dual stimuli responsiveness was prepared by introducing two phenylboronic acid groups and etching template by two-step colloidal template polymerization. Fourier transform infrared spectroscopy, nuclear magnetic resonance and transmission electron microscopy And dynamic laser light scattering and other means of its characterization. The results show that the hollow nanometer hydrogel consists of poly (N-isopropylacrylamide) and poly (N-phenylboronic acid-acrylamide), has an interpenetrating polymer network structure and a hollow structure in the interior, Dual stimulation of glucose and temperature responsiveness.
