Problems solved by technology

[0004] Synthetic fibers are prone to static electricity due to poor hygroscopicity, and are more likely to accumulate static electricity in a low-humidity environment. The accumulation of static electricity in the use of textiles can easily cause discomfort and absorb dust, which directly affects the use effect and experience.

Embodiment 1

[0021] Accurately weigh 13 g of lithium fluoride and add it to a polytetrafluoroethylene beaker filled with 200 ml of hydrochloric acid (9M). After fully dissolving, slowly add 10 g of titanium aluminum carbide powder within ten minutes; seal the beaker and stir at 40 °C 18 h. The precipitate was separated by centrifugation, washed with water until pH>5, and then dispersed in 200 mL of absolute ethanol. Centrifuge after sonication for 1 h. The precipitate was dispersed in 1 L of deionized water and ultrasonicated for 30 min. After centrifugation at 3500 rpm for 5 min, the upper titanium carbide few-layer dispersion was obtained. Add 0.2 g of ammonium bicarbonate to the titanium carbide dispersion, let stand after stirring, centrifuge, collect the precipitate and wash with ethanol. Add 5 g of the precipitate to 100 mL of glycerin, then add 0.2 g of polyvinylpyrrolidone, stir for 3 h to make it well dispersed, and obtain nano-titanium carbide conductive paste.

Description

technical field [0001] The invention belongs to the technical field of material preparation and application, and relates to a preparation method of titanium carbide and its application on textile fibers. Background technique [0002] The emerging 2D inorganic nanomaterial MXene has good conductivity and hydrophilicity, and its precursor MAX (M n+1 AX n ) phase ceramic is a ternary layered compound. (M is a transition metal element; A represents Si or Al element; X represents C or N element; n is 1-3). The general chemical formula of Mxene is M n+1 x n T X , T represents -OH, -F, =O and other groups on the surface of the material. In 2011, Gogotsi et al first used hydrofluoric acid solution to selectively etch the MAX phase (Ti 3 AlCl 2 ) in the Al atomic layer to obtain an ultrathin two-dimensional nanomaterial Ti 3 C 2 T X (MXene), which has graphene-like properties and a single layer thickness of less than 1 nm. In 2014, Ghidiu et al. used LiF and HCl to prepar...
