I added 3mass% ethanol to PET/HFIP solution and carried out electrospinning, but the nanofiber I got have beads clumped together. Is this normal? Why?

30 March 2024 0 2K Report

I added 4mass% also get the results of beads clumped together. Is it because the ethanol does not mix well with PET/HFIP?
