Abstract

Fullerene derivatives are widely applied to solar cells, cosmetics, biological medicine and other aspects; metallic oxides are applied to catalysis, semiconductor devices, energy storage and other aspects due to the advantages of good stability, easiness for preparation, controllable morphology and the like. The invention provides a preparation method for preparing a composite material by mixing a hydrophilic fullerene derivative with titanium dioxide, zinc oxide, aluminium oxide and other inorganic oxides. A flexible ether oxygen chain contained in the fullerene derivative disclosed by the invention is used for providing a hydrophilic group and improving the compatibility of the hydrophilic group and the oxide; in addition, polyvinyl alcohol and polyvinylpyrrolidone polymer are introduced as a thickening agent and a film forming agent. The composite materials can be prepared into nano-powder body, films or porous materials, have the advantages of high stability and strength, controllable morphology, easiness for processing and the like and can be used as plates, films, coatings, filling particles and the like for clearing free radicals in smog or atmosphere, resisting bacteria and being taken as battery active layers and the like.

Description

technical field [0001] The invention relates to a method for preparing a composite material of hydrophilic fullerene derivatives and metal oxides. Background technique [0002] Fullerene is the third allotrope of carbon discovered in 1985 after diamond and graphite. C 60 The molecule is aromatic, and its unique molecular structure and physical and chemical properties make fullerenes widely used in many fields such as semiconductors, catalysts, battery materials, lubricants, and biomedicine. [0003] The large conjugated system of fullerene makes it have a special ability to absorb free radicals, such as hydroxyl radicals, alkyl carbon radicals, superoxide anion radicals, etc. In the human body, free radicals play an important role in metabolism and life activities. In modern society, with the increase of pressure, the intensification of various electromagnetic radiation, and the excessive use of chemicals, the level of free radicals in the human body far exceeds the norma...
