Layer by layer nanocomposite filter for ABC filtration

Abstract

A multifunctional layer by layer nanocomposite air filter was fabricated by using electrospinning method. Polyacrylonitrile (PAN) nanofibers incorporated with silver nanoparticles (Ag NP) acts as first layer and PAN nanofibers incorporated with magnesium aluminate nanoparticles (MA NP) acts as second layer which was placed between polypropylene spun bonded nonwoven (PP SBN). The morphology of the prepared nanocomposite filter was studied by scanning electron microscopy. The performance of the filter was evaluated against i) bacterial filtration efficiency (BFE) with inhibition property ii) PM2.5 aerosol filtration efficiency (AFE) and iii) chemical detoxification efficiency. The developed nanocomposite air filter showed 99% filtration efficiency against bacterial agent & PM2.5 and 95% detoxification against 2-choloro ethyl ethyl sulfide (2-CEES). The result obtained showed that the developed layer by layer nanocomposite filter has the potential application against ABC removal.
