A lot of processes are evolved in Electrospinning, such as evaporation of the solvent. Currently, parameters are chosen emprically. So one of the question is how to make electrospinning more controllable. Does anybody tried electrospinning at a cleanroom environment? Does it make a difference?
Spinning in a cleanroom makes "no" difference on the electrospinning side. It keeps your product clean afterwards, since most electrospun products have a tendency to attract dust.
Electrospinning does require a tight control on all parameters, and the environmental parameters are often a crucial factor. But they have to be stable and controlled, clean is a nice to have.
Dear Fushan Zhou,
In general, only working parameters can affect the controllability of the electrospinning process. Importantly, the most affecting parameters on the spinnability of electrospun fibers are polymers concentration and relative humidity.
Herein, I would like to recommend these 3 papers about the effect of solution parameters, ambient parameters, and processing parameters on the spinnability and secondary surface morphology of electrospun PVDF nanofibers:
"Zaarour B, Zhang W, Zhu L, et al. Maneuvering surface structures of polyvinylidene fluoride nanofibers by controlling solvent systems and polymer concentration. Text Res J 2019; 89: 2406–2422. "
"Zaarour B, Zhu L, Huang C, et al. Controlling the secondary surface morphology of electrospun PVDF nanofibers by regulating the solvent and relative humidity.
Nanoscale Res Lett 2018; 13: 285."

Best Regards.
