[0004] Chinese patent document 201310131520.1 discloses a method for rapid preparation of graphene powder by freeze filtration, which prepares graphene into a suspension and then quickly prepares powder by drying, but due to graphene and Ti 3 C 2 Ceramics belong to two different materials with different physical properties (i.e. dispersibility, interaction between solids, hydrodynamic state, rheological behavior), and the inevitable drying process is different. The drying process is different, and the process performance of the powder different, and the drying process is not disclosed in this document

Embodiment 1

[0027] Using 400 mesh Ti 3 AlC 2 The ceramic powder is used as the raw material, using 36% concentration of hydrochloric acid and LiF mixed etching, hydrochloric acid and LiF and Ti 3 AlC 2 The ratio of ceramics is: 30:1.89:1.5. Corrosion in a water bath at 40°C for 24 hours, the corrosion product was washed with deionized water and centrifuged until the supernatant was neutral; the MXene powder was mixed with deionized water again and dispersed by ultrasonic vibration for 1 hour, and the liquid after ultrasonic vibration was manually oscillated 20min, again dispersed by ultrasonic vibration for 1h, and then centrifuged for 3min to obtain Ti 3 C 2 Suspension of nanosheets. Put 200ml of the suspension into a small spray dryer for rapid drying to prepare uniform and few-layered Ti 3 C 2 For flake powder, the air inlet temperature is 180°C, the air outlet temperature is 80°C, and the feed rate is 300ml / h. The bulk density of the prepared powder is 0.197g / ml.

Embodiment 2

[0029] Using 400 mesh Ti 3 AlC 2 The ceramic powder is used as the raw material, using 36% concentration of hydrochloric acid and LiF mixed etching, hydrochloric acid and LiF and Ti 3 AlC 2 The ratio of ceramics is: 30:1.89:1.5. Corrosion in a water bath at 40°C for 24 hours, the corrosion product was washed with deionized water and centrifuged until the supernatant was neutral; the MXene powder was mixed with deionized water again and dispersed by ultrasonic vibration for 1 hour, and the shaken liquid was shaken manually for 20 minutes , disperse again by ultrasonic vibration for 1 h, and then centrifuge for 3 min to obtain nanosheet Ti 3 C 2 suspension. Inhale 200ml of the suspension into a small spray dryer for rapid drying, resulting in the preparation of uniform and few-layered Ti 3 C 2 For flake powder, the air inlet temperature is 180°C, the air outlet temperature is 80°C, and the feed rate is 400ml / h. The bulk density of the prepared powder is 0.213g / ml.
