Abstract

The invention discloses a LiNbO3 / PAN compound nanofiber electret anti-haze window screening and a preparation method thereof. The window screening comprises three fiber membranes which are a core layer, a substrate and an upper layer. The core layer is LiNbO3 / PAN compound nano fibers, the substrate is a silver plated high molecular netty structure, and the upper layer is a black dacron non-woven fabric. The LiNbO3 / PAN compound nano fibers are adhered to the silver plated high molecular netty structure by means of electrospinning to obtain the silver plated netty structure through which the LiNbO3 / PAN compound nano fibers are attached. The silver plated netty structure through which the LiNbO3 / PAN compound nano fibers are attached is attached to the black dacron non-woven fabric through ultrasonic waves. The LiNbO3 / PAN compound nanofibers are prepared by means of electrospinning. The average diameters of the nanofibers are about 100 nm, and the nanofibers are high in strength and good in filter effect and are easily attached to the high molecular non-woven fabric.

Description

technical field

[0001] The invention relates to the field of air filtration, in particular to a LiNbO 3 / PAN composite nanofiber electret anti-smog window screen and a preparation method thereof, which are applied to filter fine particles such as PM2.5. Background technique

[0002] Many people know what smog is, but they don't have a clear understanding of why smog can cause great harm to the body. It should be known that smog is mainly composed of air particulate pollutants (particulate matter, PM). The aerodynamic diameter range of PM in the environment is about 0.001-100um, and the most harmful to the respiratory tract is the aerodynamic diameter ≤ 10 um. The main sources of inhalable particulate matter PM10 and fine particulate matter PM2.5 ≤ 2.5um are dust, construction debris, waste from dye combustion, industrial air emissions, etc., which carry harmful fungi, bacteria, Viruses and even harmful gases such as sulfur dioxide, carbon monoxide, and carbon dioxide.
