Abstract: This present invention discloses a polymer/potassium permanganate composite film obtainable by a process comprising the steps of using silane coupling agent for surface treatment of potassium permanganate, mixing 0.15-0.75 g of modified potassium permanganate with 10-20 g of polymers together to obtain a mixture, and coating the mixture to obtain a composite film. The composite film can absorb ethylene generated by fruit, thus extending fruit ripening time, keeping fruit fresh. It can be widely used as food packaging materials. The composite film also has a good oxygen barrier property and has a good efficiency to remove bacteria. Therefore it can be widely used in the pharmaceutical industry. The preparation method is scientifically sound, simple, and has high level of operability, thus making it possible for batch preparation.

Abstract: A method for in-situ generation of nanoflower-like manganese dioxide catalyst on filter material is provided. The method comprises: immersing a filter material in a solution containing sodium lauryl sulfate and nitric acid; first modifying the surface of the filter material by using the sodium lauryl sulfate so that a charge layer is wound around the surface of the filter material and tightly absorbs H+ in an acid solution; and then adding potassium permanganate as an oxidant to react with H30 on the surface of the filter material to generate nano flower-like manganese dioxide in situ on the surface of the filter material, so as to obtain a composite filter material having a denitration function.
