The metal core capillary tubes of Electrospinning were clogged with PVA/chitosan polymer. We soaked it in hot water and acetic acid solution (%5), but there was no change. How can we dissolve this polymer?
The clogging of the capillary tubes in electrospinning can be a common issue, and the method you tried (soaking in hot water and acetic acid solution) may not be effective for dissolving PVA/chitosan polymers. Here are a few alternatives to consider:
Asif Mohd Itoo Thank you for your answer.
We tried increase the temperature of hot water and acetic acid solution but there was no change. Also we tried soaking the tube to DMSO solvent, there was a little dissolve. Now we are trying soaking the tube to %5 H2SO4 solution. I hope it can dissolve.
Sonication is what i would try with proper solution. A bath sonicator might do the trick.
Omar Gonzalez-Ortega I will try bath sonicator. Thank you for your answer.
