Embodiment 1

[0022] The area will be 10 × 10cm 2 The carbon nanotube film was soaked in hydrochloric acid for 6 hours, rinsed with deionized water and ethanol respectively, then soaked in concentrated nitric acid for 6 hours, rinsed with deionized water and ethanol again, and placed in an oven at a constant temperature of 60 °C. After drying, a two-step acid-treated carbon nanotube film sample was obtained.

Embodiment 2

[0024] On the basis of Example 1, the two-step acid-treated film was immersed in SnCl 4 , NaOH and SbCl 3 In the mixed reaction solution, the solvent is a mixture of deionized water and ethanol, hydrothermally heated in a 150°C reactor, rinsed and then dried; finally, the dried film is placed in a tube furnace and heated in an inert gas N 2 Under the protection, the temperature was raised to 500°C for 20 minutes at a rate of 5°C / min. After cooling, the film was taken out to obtain the final product, antimony-doped SnO. 2 @Carbon nanotube composite electrothermal film material.

Embodiment 3

[0026] SnCl 4 , NaOH and SbCl 3 The mixed reaction solution of SbCl 3 Removed, other conditions are the same as in Example 2 to obtain SnO 2 @Carbon nanotube composite film material.

Abstract

The invention proposes to combine the advantages of two types of electrothermal materials to prepare an antimony-doped SnO 2 @Carbon nanotube composite electrothermal film: Sb-doped SnO by hydrothermal method 2 When loaded on the carbon nanotube film, its electrothermal performance is significantly improved compared with the pure carbon nanotube film, the resistance is decreased, the power required to rise to the same temperature is smaller, and the heating rate is faster; the composite film of the present invention is a kind of use A new type of flexible electric heating material that is convenient, energy-saving and environmentally friendly, and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of preparation of electric heating film materials, in particular to an antimony-doped SnO 2 @The preparation method of carbon nanotube new composite electrothermal film material. Background technique [0002] Electrothermal film technology is a new type of electrothermal conversion technology, which can effectively save energy costs and improve energy efficiency. Among them, the metal oxide electrothermal film stands out among many materials with the advantages of low resistivity, stable performance at high temperature, strong anti-oxidation and chemical corrosion resistance, simple manufacturing method, readily available raw materials, and low price. [0003] Carbon nanotubes have high thermal conductivity, but carbon nanotube films still have the problems of low thermal conversion rate and poor long-term stability in the field of electric heating. SnO 2 The thin film is a kind of transparent conductive ...
