AB  - Particulate matter 2.5 (PM2.5) pollutant particles have been identified as significant participants in air pollution, thus, special attention is paid to air filtration as a method of their efficient removal. A novel and simple method of producing nanofiber-based filters for efficient PM2.5 capture with multiple active components are proposed. Electrospun polyacrylonitrile (PAN) polymer was used both as a base filter material and as a precursor for producing microporous carbon nanofibers (MCNFs), which incorporated into the nanofibrous structure of the filter media. The fabricated PAN/MCNFs filters could reach removal efficiency of PM2.5 pollutant particles of up to 99% for with polluted air airflow velocity of 500 ml min−1, showing greater pollutant particle binding affinity with incorporated MCNFs. Experiments also show enhanced mechanical and thermal properties of studied air filters, with the addition of MCNFs – more than 4% and 6% increase in storage modulus and cyclization temperature in comparison to the base PAN filter, respectively. While using a facemask with inserted PAN/MCNFs filter, a reduced temperature variation in the facial region of the user was recorded – several degrees less when compared to a commonly used 3 M Aura 9320+ mask. This opens a possibility of their application in both industrial air filtering and as filters in facemask production.

AB  - Air pollution is often related to increased concentration of particulate matter 2.5 (PM2.5)
pollutant particles in the air. One of the methods of their removal is air filtration. Hereby, a
novel and simple method of producing nanofiber-based air filters with multiple active
components for highly efficient PM2.5 capture is proposed. Micro-porous carbon nanofibers
(MCNFs) were produced by carbonizing electrospun polyacrylonitrile (PAN) polymer and
was later incorporated into the nanofibrous structure of the filters, which itself was made
from electrospun PAN, achieving the production of two active components of the filter from
one starting material, simplifying the production process. When compared to the base PAN
filter, PAN/MCNFs filter exhibits greater filtering properties with almost absolute pollutant
particle removal. Their improved thermal and mechanical properties make this kind of filters
suitable for harsh-condition environments, such as those in industrial plants. The possibility
of using studied filters in facemask production was studied and reduced temperature
variation was recorded when using a facemask with an inserted PAN/MCNFs filter, thus
increasing wearing comfort for the user. All mentioned properties open a potential possibility
for these filters to be used in different environments, but also leave room for further
improvement.
