摘要 间苯二酚-甲醛(Resorcinol formaldehyde,RF)气凝胶是一种具有大的比表面积、高的孔隙率、好的储氢性能的一类新型储能材料,常被用作惯性约束聚变的靶丸材料。工业上常采用溶胶-凝胶法制备RF气凝胶,但这种方法制备时间长,不能满足大批量生产需求。针对这个问题,提出了一种新型的制备方法———紫外光引发法,论述了这类方法的机理、优势、研究进展和存在的问题。 Resorcinol formaldehyde aerogels is a new type of hydrogen storage material.It has a large specific surface,high porosity and good hydrogen storage performance.It's used as inertial confinement fusion pellet material.Industry often prepared it by sol gel method,because of long preparation time,it can't meet the requirement of mass production.Aiming at this problem,the paper puts forward a new kind of preparation method-UV irradiation,introduces the mechanism,advantages,research progress and existing problems.
