Verified technology for the optimized plasma treatment of fiberglass and polyester meshes to enhance the adhesion of electrospun nanofibers

Popis výsledku v původním jazyce

The aim of this verified technology was to perform experiments on plasma treatment of fiberglass and polyester meshes to enhance the adhesion properties between the material and the deposited Polyvinylidene fluoride (PVDF) nanofibers for their future usage as air filters. A Diffuse Coplanar Surface Barrier Discharge (DCSBD) was used as a plasma source.

Technické parametry

An atmospheric pressure plasma source was used for treatment, namely Diffuse Coplanar Surface Barrier Discharge (DCSBD) in planar electrode configuration. The used exposure time ranged from 1 to 10 seconds. Plasma was generated as a surface dielectric barrier discharge in air at atmospheric pressure at a supplied sinusoidal high voltage of 15-30 kHz frequency and amplitude of 10 kV. The tested power of the DCSBD was in the range of 400 - 600 W.

Ekonomické parametry

Plasma pre-treatment of the carrier substrate leads to improved adhesion of the nanofibers to the carrier substrates. This step could omit the lamination step for some types of products using nanofiber membranes (e.g., drapes). The treatment of the nanofiber layer leads to partial sintering and fixing of the fibers together, which again improves their mechanical abrasion resistance. The nanofibers treatment also leads to their chemical modification, which can improve, for example, their wettability and thus their permeability to liquids. Leaving aside the acquisition costs of the plasma treatment apparatus, operating costs can only be expected to be associated with electricity consumption.
