I do electrospinning the flowing solution to reach ZnO after calcination:
I add 0.75 g Zinc acetate in 5 ml distilled water
then I do ultrasonic for 5-10 min
then I add 0.75 g PVA ( 89000-98000 Mw) to the solution
and I stir it for 2 hours at 80 degrees c.
but I can not have continuous electrospinning
so I add triton X( 1% of 5ml solution) to reduce surface tension.
at the beginning of electrospinning, it is ok but after about 40 minutes it goes to fail.
the needle is clogged and there is no jet.
do you have a suggestion?
You can use needleless electrospinning machine or increase pva ratio.
Clogging can occur due to various reasons which includes initiation of cross-linking/chemical reaction or increasing viscosity due to some reason.
I hope after 40 min the zinc acetate precipitate and settled in the bottom so it may one of cause. Better if you increase the ultrasonication longer time. Did you observe any settings after 40 min solution? Please check if ye.
