Abstract
In recent years the electrospun nanofibre membranes have gained a great deal of attention due to their unique contribution of properties such as small pore size fine fibre diameter light weight and larger surfacetovolume ratio compared to bulk fibres and film 1 2 3 Such membranes fabricated by spinning fibres in the presence of an electric field known as electrospinning A charged jet of polymer solution is accelerated across a distance and is deposited onto the grounded collector as nanofibresMembrane thickness is one of the crucial properties for electrospun membrane In air filtration the membrane thickness has significantly influenced the membrane permeability 4 5 A number of studies have been carried out on filtration properties of electrospun membrane 4 5 6 7 8 9 10 Barhate and Ramakrishna 7 reported that one of the characteristics of nanofibrous filter media is the membrane thickness Two common methods for thickness measurement of
