In this work, the silver nanoparticles (AgNPs) were produced by liquid phase reduction method and were added into polyvinylidene fluoride (PVDF) solutions at a ratio of 0.2%, 0.4%, 0.6%, 0.8%, and 1% for electrospinning. Finally durable antibacterial property was successfully developed by adding AgNPs and by creating tree-like structure fibers.
Traditional polymer nanofibers can only remove PM from the flue. The purpose of this research is to study the adsorption capacity and selective permeability of hybrid nanofiber filter media based on polyacrylonitrile (PAN).
To prevent the spread of bacteria and viruses, personal protection must be mandatory to use masks. Here, we report a three-layer cotton-PLA-cotton biodegradable mask that contains encapsulated phytochemicals in the internal filter layer. The innovative masks using this material will bring very gratifying results to daily life and medical front-line use.
The main purpose of this research is to produce high-efficiency nanofiber filters with long-term antibacterial properties and to confirm the function of samples under actual filtration conditions. . Based on this study, it can be concluded that nanofibers with well-researched durable antibacterial properties may be recommended as excellent materials for water and air filtration applications.
The research group to create an effective multifunctional biological air filter having antibacterial and filtration properties by combining nanotechnology and biotechnology techniques. AgNPs introduced imparts zNFs-Ag @ PT filter potent antimicrobial activity and provide anisotropy field as a substrate, and are arranged to achieve tensile finer than the free form of AgNPs nanofibers fibers.
The focus of this research is an air filter with antibacterial and antiviral properties that can efficiently remove particulate matter (PM). Research on air filter materials is important for removing air pollutants and preventing the spread of respiratory infectious diseases.
(PM) The smaller the size, the deeper it can enter the lungs and bronchi, causing a series of health problems. Traditional electret air filters used in HVAC systems cannot effectively remove PM2.5. The electrospinning process can produce fibers of various diameters, including ultra-fine yarns. Which involves polyacrylonitrile (PAN) fiber.
Here, we have developed a composite nanofiber that can withstand temperatures up to 400 degrees Celsius. Due to the thermal stability and relatively high filtration efficiency, this nanofiber material has a good use value for working in a high temperature environment.
This article reports on materials and structures developed by bionic thinking. The properties and process parameters of the polymer solution were customized by electrospinning, and a multi-scale dendritic nanofiber membrane was prepared. The effects of salt type, salt content and processing parameters on the morphology and performance of TLNM are reported.
Most masks currently used to prevent the spread of COVID-19 usually do not have bactericidal properties. The chlorinated PSDT/PU nanofiber net membrane shows excellent sterilization and detoxification efficiency in a short time. The successful synthesis of PSDT/PU NNM provides innovative insights for exploring nano-mesh and sterilizing filter materials.
We have developed a multifunctional material that has ozone and PM removal functions. It is a new composite material composed of surface carboxylated polypropylene non-woven fabric and cerium-doped manganese oxide particles. The conclusion is that this composite non-woven fabric can be used for personal protection and air purification in environments involving ozone and complex pollutants.
This work developed a 3D patterned embossed nanofiber membrane (ENM) for air mask filtration, and compared this structure (EMM) with a planar nanofiber material (PNM). Compared with PNM, the relief structure enhances the developed pore structure and large surface area of NM.
