A kind of hydrophobic spherulite, hydrophobic material, hydrophobic composite material, janus composite material and preparation method and application thereof

Abstract

The present invention provides a hydrophobic crystal, hydrophobic material, hydrophobic composite material, Janus composite material and its preparation methods and applications.The structure includes micron -level crystal nucleus and nano -grade whiskers growing on the surface of the crystal nucleus; among which the hydrophobic crystal is a micro -nano structure formed by hydrophobic substances.It has better hydrophobic performance and appropriate filtration efficiency; hydrophobic materials give hydrophobic sparse crystal multifunctional properties by covering a hydrophobic sparsal crystal;The water layer makes the janus water -proof layer facilitating water vapor adsorption. The hydrophobic layer increases the concentration gradient of water vapor and realizes the directional conveying of water vapor.

Description

technical field [0001] The invention belongs to the field of materials, and relates to a hydrophobic spherulite, a hydrophobic material, a hydrophobic composite material, a Janus composite material and a preparation method and application thereof, and further relates to a hydrophobic spherulite and an application thereof. Background technique [0002] The 2019 novel coronavirus pneumonia epidemic has spread around the world. So far, tens of millions of people have been infected and millions of people have died, which has had a profound impact on public health and the global economy. The main transmission routes of the new coronavirus are respiratory droplet transmission and contact transmission. When an infected person sneezes, coughs, speaks, or even breathes, the droplets generated are mixed in the air to form aerosols, which can lead to infection after inhalation. [0003] In the fight against the new crown pneumonia epidemic, masks have become an essential protective ite...

Problems solved by technology

However, existing protective masks have significant disadvantages, including low water vapor transmission efficiency and limited ability to inhibit harmful microorganisms

The exhaled water vapor cannot pass through the mask effectively and accumulates inside it, which affects the wearing comfort. Skin soaked in sweat for a long time may even appear red, swollen and itchy

When the glasses and the mask are worn at the same time, the water vapor will easily condense on the lenses and cause fogging, which will affect the wearer's vision

[0005] In particular, existing protective masks can only partially intercept pathogens such as bacteria, fungi, and viruses on the surface of the filter layer, but cannot effectively remove and kill them.

In the end, the discarded mask filter layer takes accumulated organic pollutants as nutrients and becomes a breeding ground for pathogenic microorganisms, which is easy to cause the spread of pathogens and secondary pollution

At the same time, the accumulation of microorganisms may lead to reduced ventilation and reduced filter life
