[0049] The present invention also provides a method for preparing a metal oxide / conductive polymer cross-pattern array, which includes the following steps:
[0050] Disperse the oxidizing metal salt on the growth medium, and use a gas phase polymerization method to make the metal salt dispersed on the growth medium catalyze the reaction monomer in the gas phase to polymerize and at the same time the metal salt itself undergoes a hydrolysis reaction to obtain the first reaction product;
[0051] The first reaction product is annealed to obtain a metal oxide / conductive polymer cross pattern array.
[0052] In the embodiment of the present invention, first preparing a growth medium dispersed with ferric salt includes: adding an oxidizing metal salt to a volatile organic solvent, stirring until the metal salt is dissolved to obtain a metal salt solution; adding a growth medium to the metal salt solution , Continue to stir until the volatile organic solvent evaporates.
[0053] Among them,...
Embodiment 1
[0072] This embodiment 1 provides a method for preparing an iron oxide / poly(3,4-ethylenedioxythiophene) cruciform pattern array, which includes the following steps:
[0073] 1. Weigh 6.7575g FeCl 3 ·6H 2 O was added to 50mL of absolute ethanol, magnetically stirred until FeCl 3 ·6H 2 O completely dissolves to get FeCl 3 ·6H 2 O in ethanol solution; weigh 2g of NaCl and add to 5mL of FeCl obtained above 3 ·6H 2 In the ethanol solution of O, magnetically stir until the formation of viscous NaCl and FeCl 3 ·6H 2 O's mixture.
[0074] In this example, the viscous mixture obtained by stirring is in a state that the iron salt absorbs a small amount of water after the absolute ethanol is completely volatilized. The stirring time varies according to the environmental humidity, generally 1~1.5h.
[0075] 2. Spread the viscous mixture thinly and evenly on the nickel foam, then suspend the nickel foam on the middle and upper part of the reactor, and then measure out 0.05 mL of 3,4-ethylenedioxy...
Embodiment 2
[0082] This embodiment provides a method for preparing an iron oxide / poly(3,4-ethylenedioxythiophene) cruciform patch array polymerized in situ on a carbon cloth, including the following steps:
[0083] 1. Weigh 6.7575g FeCl 3 ·6H 2 O was added to 50mL of absolute ethanol, magnetically stirred until FeCl 3 ·6H 2 O completely dissolves to get FeCl 3 ·6H 2 O in ethanol solution; add 1cm×1cm carbon cloth to 2ml FeCl 3 ·6H 2 In the ethanol solution of O, magnetically stirred until the ethanol is completely volatilized, and the FeCl is completely infiltrated 3 ·6H 2 O's carbon cloth.
[0084] 2. It will completely infiltrate FeCl 3 ·6H 2 The carbon cloth of O was placed on the nickel foam, and then the nickel foam was suspended in the middle and upper part of the reactor, and then 0.05 mL of 3,4-ethylenedioxythiophene monomer was dropped on the bottom of the reactor.
[0085] 3. Put the above reaction kettle into a drying box with an initial temperature of 50°C, raise the temperature to 15...
