Problems solved by technology
The invention relates to a nano technology and a high polymer technology, and in particular to a polypyrrole hollow nano microsphere with a porous shell and a preparation method and application thereof. The preparation process can be carried out as follows: under an action of ferric chloride serving as an oxidant, pyrrole monomer polymerizes on a surface of nano silicon dioxide template at a low temperature, then hydrofluoric acid is used for etching, a hollow structure is formed after the template is removed, and nano-scale holes are left in the polypyrrole shell layer. The polypyrrole poroushollow nanospheres can be used as fillers for preparing gas separation membranes, pervaporation membranes, nanofiltration membranes and the like.
