Embodiment 1

[0019] The 10% polyacrylonitrile formamide solution is electrosprayed to obtain ultrafine polyacrylonitrile microspheres, and the ultrafine microspheres are carbonized to obtain ultrafine carbon microspheres.

Embodiment 2

[0021] The 30% polyacrylonitrile formamide solution is electrospun to obtain ultrafine polyacrylonitrile fibers, and the ultrafine fibers are carbonized to obtain ultrafine carbon fibers.

Embodiment 3

[0023] The 5% polystyrene ethyl acetate solution is sprayed into the water flow tube flowing in the same direction at a speed of 500,000 droplets / second through a 200-micron spray hole and collected in the collection pool. After drying, ultra-fine Polystyrene microspheres are obtained by carbonizing the ultrafine microspheres at high temperature to obtain ultrafine carbon microspheres.

Abstract

The invention discloses the preparation method and application of carbonic superfine materials, which is characterized in that the invention comprises the following steps: a. firstly disintermediate phase pitch materials capable of carbonizing are fluidized; b. secondly the fluidized materials capable of carbonizing are prepared into superfine materials; c. the carbonic superfine materials of the invention can be gained through carbonizing the superfine processed materials. The superfine carbonic materials prepared by the invention are used as functional materials. When using as the functional materials, the superfine carbonic materials has one or a plurality of following functions such as separating, transducing, catalyzing, storing, controlled release, structural support, absorbing and restoring. The invention is beneficial for improving the machining efficiency of the carbonic superfine materials and lowering the cost.

Description

Technical field: [0001] The present invention relates to the preparation and application of carbon-containing ultrafine materials, in particular to prepare non-mesophase pitch carbonizable materials into ultrafine fine material, and then carbonize the ultra-fine carbonizable material to obtain carbon-containing ultra-fine material. The ultrafine carbon material prepared by the invention is applied as a functional material. When this ultrafine carbon material is used as a functional material, it has one or more of the functions of separation, sensing, catalysis, storage, controlled release, structural support, adsorption, and repair. This technology can prepare carbon-containing ultrafine materials cheaply and on a large scale, so it is expected to help broaden and improve the application of carbon-containing ultrafine materials. Background technique [0002] Ultrafine carbon materials refer to materials including ultrafine carbon particles and ultrafine carbon fibers with ...
