美国斯坦福大学的研究人员发明了一种用天然材料制造水凝胶的新工艺,所制备的水凝胶安全、伸缩性好、成本低廉,或实现水凝胶的工业化规模生产,可应用于食品加工、消防等方面。研究人员研制的新型水凝胶包含两种低成本且来源丰富的基本原料,一种是取自木屑、农作物秸秆等天然材料的纤维素聚合物,另一种是取自沙子的胶态二氧化硅纳米粒子。将两种材料混合起来,可以获得稳定的水凝胶。研究人员称,该新型水凝胶具有广阔的应用前景。例如, Researchers at Stanford University in the United States invented a new technology for making hydrogels from natural materials. The prepared hydrogels are safe, scalable, low cost, or industrial scale production of hydrogels and can be applied to foods Processing, fire and so on. The new hydrogels developed by the researchers include two low-cost, abundant-sourced base stocks, one from cellulose polymers derived from natural materials such as sawdust and crop straws, and the other from colloidal dioxins taken from the sand Silicon Nanoparticles. By mixing the two materials, a stable hydrogel can be obtained. The researchers said the new hydrogel has broad application prospects. E.g,
