Abstract

The invention belongs to the field of preparation of conductive composites and in particular relates to a preparation method and application of a one-dimensional rod-spherical attapulgite / polyaniline conductive composite. Attapulgite rod crystals are taken as a carrier, firstly, iron oxide nanoparticles are loaded on the surfaces of the attapulgite rod crystals, and then released Fe<3+> is utilized for oxidizing a phenylamine monomer on the surface of iron oxide in an iron oxide self-dissolution process, so that the rod-spherical attapulgite / polyaniline conductive composite is formed. The conductive composite can be applied to paint.

Description

technical field [0001] The invention belongs to the field of conductive composite material preparation, and in particular relates to a preparation method and application of a rod-spherical attapulgite / polyaniline conductive composite material. Background technique [0002] The coating formed by coating the coating on the base material generally has the phenomenon of static electricity accumulation. At present, this problem is mainly solved by adding conductive powder to the coating. Most of the conductive powders commonly used in the market are spherical, with a large amount of addition, which is easy to cause precipitation and affect the mechanical properties of the matrix resin. Therefore, the development of fibrous conductive materials has become an inevitable trend of its development. The core material of the current fibrous conductive filler is mainly artificially synthesized fibrous potassium titanate, acicular titanium dioxide, etc., and the conductive film layer is m...
