Investigation On The Filtration Efficiency Of Nanofiber-Coated Vehicle Cabin Filter

In a conventional vehicle in filter, layers of fibrous filtering material are fixed together with a support surface. Vehicle cabin filter has a combined filter which not only will trap dust and they catch unpleasant odours and toxic gasses. However, the conventional cabin filter are not enough to fi...

description	In a conventional vehicle in filter, layers of fibrous filtering material are fixed together with a support surface. Vehicle cabin filter has a combined filter which not only will trap dust and they catch unpleasant odours and toxic gasses. However, the conventional cabin filter are not enough to filter the harmful emissions efficiently especially particles in nanometric scale for example PM, particulates.This study is therefore intended to develop and study the performance of nanofiber-coated filters. Electrospining technique were used to produce the the nanofiber-coated filters. The filter were cut in to small pieces and coated with the PYOH nanofibers which is electrospun at 10kV of applied voltage. A dedicated air filtration test rig was designed and fabricated to evaluate the performance of the filter. The method of measuring particulate matter (PM) was used to determine the density of air particles (mg/m?) across the tube. The filter samples of 1 minute to 12 minutes of nanofiber-coating were fabricated. The results measured shows, as the electrospining time increases, the nanofiber-coating also increases. The increase in anofiber-coating also increases the filtration efficiency. The percentage of filtration efficeincy in particulate matter (ppm) based in the inlet and outlet were measured. The filter with 1 minute nanofiber-coating recorded 8.89% of filtration while the filter with 12 minutes nanofiber-coating has an efficient filtration of 39.29% for PM; particulates. Scanning electron microscope (SEM) was used to examine the morphology of the nanofiber. The size of the nanofiber diameter were measured and compared using the ImageJ software and from the results it shows that there is no significant difference in between the diameter of nanofibers in the nanofiber-coated filters. This shows that the diameter of nanofiber is maintained. The study also shows promising results that, longer nanofiber collection time created a thicker layer of nanofibers that were coated on the substrate filters. These filters showed higher filtration capacity to filter fine particulate matter especially PM10 particulates.
