Problems solved by technology

Due to the large amount of foot movement and a lot of sweating, and the environment inside the shoes is closed, it is easy to breed bacteria and have adverse effects on the health of the feet. For example, it is easy to be infected with various skin diseases, such as athlete's foot, foot sweat, Smelly is a common disease in daily life. It is a skin disease caused by fungal infection, which brings a lot of inconvenience to people's daily life.

Embodiment 1

[0042]Put a 250mL reaction bottle in an ice bath, add an appropriate amount of concentrated sulfuric acid, add a solid mixture of 2g graphite powder and 2g sodium nitrate while stirring, then add 6g potassium permanganate, stir for 40min, then add 2mL of 30% hydrogen peroxide, continue to stir for 10 minutes, filter while hot, wash with deionized water three times, and dry in a vacuum oven at 60°C for 24 hours. Calcinate the dried solid at 400°C for 2 hours under the protection of nitrogen to obtain reduced graphene powder; add 30 mg of graphene powder to 60 mL of absolute ethanol, and ultrasonically disperse for 1 hour to obtain a graphene dispersion in absolute ethanol. Add 3-5 drops of concentrated nitric acid dropwise, then slowly drop 15mL of n-butyl titanate into the dispersion, continue to stir for 1 hour, then centrifuge the mixed colloid obtained above, and wash it with absolute ethanol several times before putting it in Dry in a vacuum oven at 60° C. for 24 hours, an...

Embodiment 2

[0046] Put a 250mL reaction bottle in an ice bath, add an appropriate amount of concentrated sulfuric acid, add a solid mixture of 2g graphite powder and 1g sodium nitrate while stirring, then add 6g potassium permanganate, stir for 40min, then add 2mL of 30% hydrogen peroxide, continue to stir for 5 minutes, filter while hot, wash with deionized water three times, and dry in a vacuum oven at 60°C for 24 hours. Calcinate the dried solid at 350°C for 3 hours under the protection of nitrogen to obtain reduced graphene powder; add 15 mg of graphene powder to 60 mL of absolute ethanol, and ultrasonically disperse for 2 hours to obtain a graphene absolute ethanol dispersion. Add 3-5 drops of concentrated nitric acid dropwise, then slowly drop 15mL of n-butyl titanate into the dispersion, continue to stir for 1 hour, then centrifuge the mixed colloid obtained above, and wash it with absolute ethanol several times before putting it in Dry in a vacuum drying oven at 50°C for 20h, and ...

Embodiment 3

[0050] Put a 250mL reaction bottle in an ice bath, add an appropriate amount of concentrated sulfuric acid, add a solid mixture of 2g graphite powder and 2g sodium nitrate while stirring, then add 6g potassium permanganate, stir for 40min, then add 2mL of 30% hydrogen peroxide, continue to stir for 10 minutes, filter while hot, wash with deionized water three times, and dry in a vacuum oven at 60°C for 24 hours. The dried solid was calcined at 400°C for 2 hours under nitrogen protection to obtain reduced graphene powder; 60 mg of graphene powder was added to 60 mL of absolute ethanol, and ultrasonically dispersed for 3 hours to obtain a graphene absolute ethanol dispersion. Add 5 drops of concentrated nitric acid dropwise, then slowly drop 15mL of n-butyl titanate into the dispersion, continue to stir for 2 hours, then centrifuge the mixed colloid obtained above, and wash it with absolute ethanol for several times, then put it into vacuum drying The oven was dried at 60° C. fo...

Abstract

The invention discloses applications of a composite photocatalytic material, sterilizing and deodorizing shoe-pads, sterilizing and deodorizing shoes, and preparation methods. The composite photocatalytic material is composed of graphene and titanium dioxide, and after the composite photocatalytic material is used for preparing the sterilizing and deodorizing shoe-pads, the shoe-pads have the efficient sterilization function; the composite photocatalytic material also can be used for preparing a fungus purifying box, and the fungus purifying box can be used in domestic daily life, and can be placed in domestic shoe cabinets for killing various dermatophytosis fungi, so that the cross infection of dermatophytoses can be prevented. The composite photocatalytic material has no selectivity in killing fungi generated at the feet, can be used for removing 97% or above of fungus varieties, is low in cost and simple in process, is natural and environmentally friendly, and is safe and harmless to the human body.

Description

technical field [0001] The invention relates to an insole, in particular to an application of a composite photocatalytic material, a sterilizing and deodorizing insole, shoes and a preparation method. Background technique [0002] Nowadays, as people's pace of life is accelerating and their work is getting busier, people are paying more and more attention to self-care. The foot is a very important part of the human body. It is densely covered with rich capillaries and important acupuncture points. The health care and physical therapy of the feet can eliminate the fatigue of the whole body. Due to the large amount of foot movement, the sweating, and the closed environment inside the shoes, bacteria are easy to breed and have adverse effects on the health of the feet. Smelly is common disease in daily life, is the skin disease that is caused by fungal infection, brings many inconveniences to people's daily life. [0003] Therefore, the prior art has yet to be developed. Co...
