Embodiment Construction

[0030]The polyaniline / carbon black composite is formed by polyaniline covering carbon black and is with core-shell structure while the polyaniline / carbon black composite contains 10˜30 wt. % of carbon black.

[0031]The particle diameter of the carbon black particle is 10˜80 nm and the particle diameter of the polyaniline / carbon black core-shell particle ranges from 50 to 250 nm (from observation of Transmission electron microscopy (TEM)). The preferable weight percent of carbon black in the polyaniline / carbon black composite is 20 wt. %.

[0032]Refer to FIG. 1, a preparation method of polyaniline / carbon black composite according to the present invention includes the steps of:

[0033]S1 disperse carbon black into solution to form carbon black solution;

[0034]S2 add aniline into the carbon black solution to form a first solution;

[0035]S3 dissolve ammonium persulfate into acid aqueous solution to form a second solution;

[0036]S4 add the second solution to the first solution for reaction, then ...

Abstract

A polyaniline/carbon black composite and a preparation method thereof are disclosed The polyaniline/carbon black composite is formed by polyaniline covering carbon black and is with core-shell structure while the polyaniline/carbon black composite contains 10-30 wt. % of carbon black. The preparation method of polyaniline/carbon black composite includes the steps of: disperse carbon black into solution to form carbon black solution, add aniline into the carbon black solution to form a first solution; dissolve ammonium persulfate into acid aqueous solution to form a second solution; add the second solution to the first solution, after reaction, through filtering and grinding to produce polyaniline/carbon black composite.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a polyaniline / carbon black composite and a preparation method thereof, especially to a polyaniline / carbon black composite and a preparation method thereof that are applied to dielectric material with microwave absorption or conductive coatings with corrosion resistance.[0002]The research and development of conductive coatings have been over a half-century. Working as conductive layer, electromagnetic wave shielding layer and antistatic coating, the conductive coatings have broad perspective and increasing market demands. The membrane surface of the conductive coating has higher resistance, charge generated thereon is not dissipated effectively so that static charges tend to accumulate thereon. This leads to certain limitations on applications of some respects such as dust proofing and bacteria resistance in medicine, protection from electric shock in medical operations, static protection for preventing static ignition...
