According to the present invention, a noncovalent bond-modified carbon structure has advantages of: enabling the control of properties by controlling intervals between carbon structures according to the size and structure of a compound represented by Chemical Formula 1, which is inserted and adsorbed between the carbon structures; and enabling uniform dispersion in a polymer matrix without a change in intrinsic properties. In addition, a carbon structure/polymer composite comprising the modified carbon structure and a polymer matrix is simply manufactured and readily layered due to excellent orientation when forming a cured coating film, and thus can be useful for manufacturing a steel sheet having remarkable heat radiation, surface polarity, electrical properties and the like.

Noncovalent bond-modified carbon structure, and carbon structure/polymer composite comprising same

A platelet-type zirconium phosphate, which has a P&#x2014;OH group contained in a structure thereof, and has a crystalline peak at a 2&#x3b8; value of 11.6&#xb1;2 degrees and no crystalline peak at a 2&#x3b8; value of less than 11.6&#xb1;2 degrees in X-ray diffraction analysis, is provided. The platelet-type zirconium phosphate has a platelet-type structure and can be uniformly dispersed at a nanoscale level in a coating film to exhibit excellent surface gloss and barrier capability. Also, the platelet-type zirconium phosphate can exhibit excellent corrosion resistance due to the presence of the P&#x2014;OH group on a surface thereof, and can be dispersed not only in an aqueous solution but also in an organic solvent.
