Abstract

The invention discloses a conductive shower-shaped microcellular foaming functional film and a preparation method thereof. The film comprises the following components in parts by weight: 0.010-0.030 parts of multi-wall carbon nano tube, 9.0-29.0 parts of polymer, 0.5-1.5 parts of foaming agent and 100 parts of organic solvent. The conductive shower-shaped microcellular foaming functional film provided by the invention is prepared from the multi-wall carbon nano tube and a polymer through blending and foaming in the organic solvent by using the foaming agent. The microcellular foaming functional film is prepared by using the foaming agent in manners of forming bubbles and molding, and does not need a template, so that the conductive shower-shaped microcellular foaming functional film has the advantages of simple preparation method, low cost and short production period; the product can be applied to the fields of a series of electrochemical energy conversion and storage equipment (for example, batteries and super capacitors), medical membrane separation and biomedical tissue engineering scaffolds and the like, and especially can be widely applied to the fields such as communication, medical treatment, bioscience, environment detection and the like as a miniature apparatus.

Description

technical field [0001] The invention belongs to the technical field of microporous foamed films, in particular to a conductive shower-shaped microporous foamed functional film and a preparation method thereof. Background technique [0002] Whether the microporous foamed films currently on the market are obtained by chemical or physical methods, the types of pores are mainly closed cells and open cells, and most of the cells are honeycomb-shaped. Pore-shaped microporous foamed film must use a specific template, which will lead to complex template making, high cost, and long production cycle. method. [0003] In addition, due to the unique physical properties of multi-walled carbon nanotubes (MWCNT), high electrical conductivity, chemical and mechanical stability, and large specific surface area, it has become one of the most concerned materials for designing functional thin films today, including catalytic Membranes, thin films for mechanical applications and a range of ele...
