Electrospinning composite micro-nano fiber air filtration membrane and preparing method thereof

Abstract

The invention discloses an electrospinning composite micro-nano fiber air filtration membrane and a preparing method thereof. The air filtration membrane is prepared through an electrospinning method, the composite micro-nano fiber of the air filtration membrane is formed by nano-silver particles, enteromorpha activated carbon / titanium dioxide composite particles and a water insoluble high-molecular polymer, wherein the enteromorpha activated carbon / titanium dioxide composite particles are prepared from electrospinning TiO2 / high-molecular polymer / enteromorpha nano particles (enteromorpha nano dry powder) composite nano fiber membrane through high-temperature heat treatment, acid pickling and smashing. The air filtration membrane is simple in preparing method, excellent in performance and capable of effectively adsorbing and decomposing formaldehyde and other harmful substances while blocking and filtering dust pollutants and has a good antibacterial function and a good comprehensive protection effect.

Description

technical field

[0001] The invention relates to an electrospun composite micro-nano fiber air filter membrane and a preparation method thereof. Background technique

[0002] Air pollution is a phenomenon in which the concentration of pollutants in the atmosphere reaches a harmful level, exceeds the environmental quality standard, destroys the ecological system and normal living conditions of human beings, and causes harm to people and things. With the development of modern industry and transportation, more and more substances are continuously discharged into the atmosphere, and the types are becoming more and more complex, causing rapid changes in the composition of the atmosphere, and the form of air pollution is becoming more and more severe. However, in addition to the air pollution caused by the industrialization process, the indoor air pollution caused by decoration cannot be ignored. There are more than 500 volatile substances in the indoor air, including more than 20 ...
