Embodiment 1

[0020] The preparation method of fabric electrode substrate comprises the following steps, as figure 1 :

[0021] (1) Take a 5cm×5cm cotton fabric, drop ethanol onto the surface of the cotton fabric, place the wetted fabric in FeCl with a mass concentration of 10g / L 3 In the aqueous solution, soak for 40min and stir at a stirring rate of 180r / min. The surface of the fabric fiber wetted by ethanol is rich in hydroxyl groups, which can attract more positively charged ions. Soak the wet fabric in FeCl 3 The aqueous solution can make the fabric fully absorb Fe 3+ , to prepare for the subsequent in-situ deposition of FeOOH;

[0022] (2) Stir the mixture of step (1) in a constant temperature water bath in a water bath at 80°C, the stirring rate is 100r / min, and the stirring time is 2 hours, Fe 3+ A hydrolysis reaction occurs to form iron oxyhydroxide and deposits on the surface of the fabric;

[0023] (3) After the product obtained in step (2) is cooled, it is cleaned and dried ...

Abstract

The invention discloses a fabric electrode substrate and application and a preparation method thereof. The fabric electrode substrate comprises a fabric modified with hydroxyl oxidize iron, and the fabric is a cotton fabric or a polyester fabric. According to the application, the fabric electrode substrate is used for preparing a fabric electrode with polypyrrole or polyaniline as a main active material. The preparation method comprises the following steps that a, the wetted fabric is placed in a FeCl3 water solution, soaked with the FeCl3 water solution and stirred; b, the mixture obtained inthe step a is stirred in a temperature-constant water bath; c, the product obtained in the step b is cooled, thoroughly cleaned and dried in sequence, and then the hydroxyl oxidize iron modified fabric electrode substrate is obtained. The preparation process of the hydroxyl oxidize iron modified fabric electrode substrate is relatively simple, the reaction time is not long, the cost is low, and large-scale production can be achieved; the single reagent FeCl3 6H2O is used as the raw material, acid or alkali or an oxidizing agent are not needed, and hydroxyl oxidize iron is directly deposited on the surface of the fabric through the hydrolysis reaction of Fe<3+> within a short time.
