Embodiment 1

[0088] In the first step, soak 1kg of activated carbon in 100ml 0.01wt% antimicrobial peptide photosensitive molecule (manufacturer: Qingdao Sunshine Power Biomedical Technology Co., Ltd.) solution, or spray 100ml 0.01wt% antimicrobial peptide photosensitive molecule solution on the surface of 1kg activated carbon, After the antimicrobial peptide photosensitive molecules are on the surface of the activated carbon, it is preferable to wash with water to remove the unadsorbed antimicrobial peptide photosensitive molecules;

[0089]The second step is to dry or dry at 50°C to obtain the PDT catalytic decomposition of formaldehyde and organic gas activated carbon particles of the present invention.

Embodiment 2

[0091] In the first step, soak 1kg ceramics in 100ml 10wt% antimicrobial peptide photosensitive molecules (manufacturer: Qingdao Sunshine Power Biomedical Technology Co., Ltd.) solution, or spray 100ml 10wt% antimicrobial peptide photosensitive molecule solution on 1kg ceramics, and the antimicrobial peptides After the photosensitive molecules arrive on the ceramic surface, it is preferable to wash with water to remove the unadsorbed antimicrobial peptide photosensitive molecules;

[0092] The second step is drying or oven-drying at 90° C. to obtain the PDT catalytic decomposition of formaldehyde and organic gas ceramic particles according to the present invention.

Embodiment 3

[0094] In the first step, soak 1kg microcrystalline cellulose in 100ml 50wt% antimicrobial peptide photosensitive molecule (Qingdao Sunshine Power Biomedical Technology Co., Ltd.) solution, or spray 100ml 50wt% antimicrobial peptide photosensitive molecule solution on 1kg microcrystalline cellulose, After the antimicrobial peptide photosensitive molecules are on the surface of the microcrystalline cellulose, it is preferable to wash with water to remove the unadsorbed antimicrobial peptide photosensitive molecules;

Abstract

The invention relates to a material for catalytic decomposition of formaldehyde and organic gas with PDT(photodynamic therapy). The material is prepared from antimicrobial peptidephotosensitive molecules and a material with hydroxyl on the surface in one or two of a chemical bonding mode and a physical curing mode. A preparation method of thematerial adopts a simple process and mild reaction conditions and is suitable for industrial production, a final PDT material product with function of catalytic decompositionformaldehyde and organic gas can be applied to preparation of an organic gas purification coating, domestic air purification and industrial air purification.

Description

technical field [0001] The invention relates to a photodynamic (abbreviated as PDT) catalytic decomposition of formaldehyde and organic gas materials and a preparation method thereof, in particular to carrying an antimicrobial peptide photosensitizer onto the surface of a material with a hydroxyl structure through chemical bonding or physical curing, and thereby The formed material with high-efficiency PDT catalytic decomposition of formaldehyde and organic gas performance belongs to the field of functional material technology and environmental governance. Background technique [0002] With the improvement of people's living standards and aesthetic tastes, high-end home decoration has become more and more popular, and various decorations, furniture, floor panels, wall decoration materials, etc. have become indispensable in home decoration. At the same time, some imperceptible gas pollutants that accompany it also bring a lot of discomfort and troubles to people, such as ammo...
