超声诱导凝胶研究进展

Progress in Ultrasound-Induced Gelation

近年来,超声诱导凝胶作为一种在室温下形成分子凝胶的新方法受到广泛关注.以分子凝胶的形成和超声作用的原理为出发点,从超声诱导溶液转变为凝胶、超声诱导沉淀转变为凝胶、超声诱导等多种手段形成的凝胶体系、超声增强的凝胶体系、超声诱导的杂化凝胶体系等五个方面,较系统地综述了近年来超声诱导凝胶的研究进展情况,简单展望了超声诱导凝胶的研究和应用前景.

In recent years, ultrasound-induced gelation, as a new method for the formation of molecular gels at room temperature, has attracted much interest. In this paper, the methods for the formation of molecular gels and the effects of ultrasound are introduced firstly. According to the sequence of ultrasound-induced gelation of solution, ultrasound-induced gelation of precipitate, ultasound as one of the trigger for gelation, ultrasound-enhanced gel and ultrasound-induced hybrid gel, the progress of ultra- sound-induced gelation is reviewed, and the perspectives of the research and application are also discussed.
