日本研究人员声称已经找到一种快速可逆的方法使溶胶-凝胶在其液态和固态之间相互转化。化学家TakeshiNaota and H iroshi Koori在大阪大学用有机溶剂溶解了一种钯的络合物,利用超声波可以使这种溶液立即转变成稳定的溶胶,加热又可以使该凝胶转变成液体。这种可逆转变可以无限 Japanese researchers claim that they have found a fast and reversible way to convert sol-gel between their liquid and solid phases. The chemist Takeshi Naota and H iroshi Koori dissolved a palladium complex with an organic solvent at Osaka University. Using ultrasonic waves, this solution was instantly transformed into a stable sol, which was heated to turn the gel into a liquid. This reversible change can be unlimited
