A study of possibility of manufacturing Nano webs of mixtures of poly vinyl alcohol with silver nitrate by electro spinning process


Abstract in English

In this study we used electro spinning technology to obtain nonwoven webs of Nano fibers of poly vinyl alcohol and Nano particles of silver . we dissolve the polymer poly vinyl alcohol in it's solvent (water) to form a polymeric solution that we charged it by positive charge and ejected it to leaving it on a collector that we charged it by negative charge and used a high voltage. and we mixed the polymer poly vinyl alcohol with silver nitrate with different concentrations and electro spinning the mixture to obtain Nano fibers and Nano particles of silver then we applied heat treatment for the whole samples at 155°c for 5 minutes for tow aims the first one is to make crosslinking between series of PVA and the second is for the stability of silver nanoparticles , finally we analyze samples on Scanning Electron Microscopy SEM .
