Abstract

The invention relates to a titanium carbide / polyaniline composite material and a preparation method thereof. The preparation method comprises the following steps: firstly, adding a two-dimensional layered nano material MXene-Ti3C2 into a hydrochloric acid solution, and uniformly dispersing to obtain a Ti3C2 mixed solution; then adding aniline into the Ti3C2 mixed solution, and uniformly dispersing to obtain a mixed solution, wherein the ratio of the aniline to the two-dimensional layered nano material MXene-Ti3C2 is (0.1 to 0.3)mL to (100 to 600)mg; at 0 to 5 DEG C, adding a catalyst into a mixed solution A drop by drop, carrying out stirring polymerization till the mixed solution is gradually changed from a transparent solution into a uniform black solution, and carrying out washing and drying to obtain the titanium carbide / polyaniline composite material. According to the preparation method, by low temperature stirring treatment at 0 to 5 DEG C, the PANI / Ti3C2 composite material is prepared, and the problem that Ti3C2 is easy to oxidize at high temperature is improved, and the composite material with a uniform load can be obtained.

Description

【Technical field】 [0001] The invention relates to the field of composite material preparation, in particular to a titanium carbide / polyaniline composite material and a preparation method thereof. 【Background technique】 [0002] Ternary layered ceramic material Ti 3 AlC 2 It belongs to layered hexagonal crystal structure. at Ti 3 AlC 2 In the crystal structure, Ti and C atoms form Ti 6 The C octahedron is separated by the Al layer, and the C atom is located in the center of the octahedron. The combination of C and Ti atoms is a strong covalent bond, while Ti-Ti, and between Ti and Al are weakly bonded, similar to the bond between graphite Van der Waals weak bonds. [0003] Ti 3 AlC 2 It has the properties of both metal and ceramics. At room temperature, it has thermal conductivity and electrical conductivity, as well as low Vickers microhardness and high elastic modulus. It can be machined like metal and can be machined at a high temperature. It is plastic at high te...
