I am trying to make alumina nanofibers. so far i have prepared a solution of 0.6925 mol/kg
using Al(NO3)3.9H2O in water, ethanol and PVP.
I started with 12%PVP but the solution was not viscous enough, so i increased to 14% and still the same issue, i had dripping, no stable jet. I changed the ethanol to water ratios and the problem was still there in addition to the solution drying on the tip of the needle.
i am not getting anything to see on my collector except the dripping.
what would be the issue here ?
