Description

technical field [0001] The present invention relates to a kind of poly-4-methylpentene (TPX) and SiO 2 The invention relates to a microsphere composite film and a preparation method thereof, which belong to the technical field of chemical preparation of organic polymer and inorganic particle composite film. Background technique [0002] Organic thin films have disadvantages such as low chemical stability, narrow temperature range, easy to be polluted, low mechanical strength, and short service life. In recent years, by incorporating inorganic particles into organic polymer films, not only the problem of difficult processing of inorganic materials has been overcome, but also some special properties (mechanics, optics, electricity, etc.) of the polymer have been enhanced. This polymer-inorganic particle composite film idea has great prospects at present and even in the future. [0003] The current chemical preparation methods of polymer-inorganic particle composite films inc...
