本刊讯(通讯员仲科)在国家自然科学基金项目支持下,日前,中国科学院兰州化学物理研究所在三维网络水凝胶材料的制备及应用研究方面取得新进展。该课题组从分子设计的角度出发,利用天然高分子壳聚糖活泼的化学反应活性和在一定条件下呈正电性的特征,在室温和空气氛条件下,实现了一步法制备粒状水凝胶产品。随后,该课题组又以水凝胶三维网络作为微纳反应器,研制出一种 Our correspondent (Zhongke) supported by the National Natural Science Foundation of China, a few days ago, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences in the three-dimensional network of hydrogel material preparation and application of new progress. The group from the molecular design point of view, the use of natural polymer chitosan active chemical reaction activity and under certain conditions were positive characteristics, under room temperature and air conditions, to achieve a one-step preparation of granular hydrogel product. Subsequently, the group with hydrogel three-dimensional network as a micro-nano reactor, developed a
