This study is mainly focused on characterization of nanomembrane using nylon-6 and its blend with poly (e-caprolactine) (PCL). Nylon-6 nanomembrane has been developed using formic acid at four different viscosity levels of 158.4, 420.8, 920.8 and 1417 cPs. Another nanomembrane of nylon-6/PCL (80:20) blend has also been developed using nylon-6 polymer solution viscosity of 1417 cPs at three different polymer concentrations (8, 10 and 12%) of PCL. The characterization of nanomebrane is done using scanning electron microscope and Fourier transformed infrared. It is observed that the nanomebrane of 80:20 blend ratio of nylon-6/PCL at 1417 cPs nylon-6 viscosity and 12 % concentration of PCL produces uniform fibre structure.
