However, due to the slow speed of suction filtration, it usually takes several days to obtain pure graphene oxide, and the amount of hydrochloric acid solution and deionized water required for suction filtration is relatively large. The Buchner funnel and container for suction filtration in the laboratory The capacity of the filter bottle and the suction filter bottle is small, so it is usually necessary to manually control the time and amount of adding hydrochloric acid or deionized water, and at the same time pour out the waste liquid in the suction filter bottle in real time. The hydrochloric acid or deionized water in the funnel is drained, and the filter membrane is broken, the graphene oxide in the Buchner funnel falls into the suction filter bottle and is polluted, and the preparation process is wasted

Description
technical field [0001] The invention belongs to the field of nanomaterial preparation, and relates to a suction filtration device, in particular to a graphene oxide suction filtration device. Background technique [0002] Since the 1990s, due to the emergence of fullerene (Fullerene) and carbon nanotubes (Carbon nanotubes, CNTs), the well-known inorganic carbon chemistry has entered a new period of development. The rapid rise of nanotechnology has made carbon nanomaterials an emerging scientific research field. The excellent physical and chemical properties and potential applications of zero-dimensional and one-dimensional carbon nanomaterials have aroused scientists' interest in studying two-dimensional carbon nanomaterials. In 2004, Novoselov and Geim, physicists at the University of Manchester in the United Kingdom, successfully stripped two-dimensional graphene from graphite, overturning the cognition that "thermodynamic fluctuations do not allow two-dimensional crystal...
