Area of Science:

  • Materials Science
  • Polymer Chemistry
  • Nanotechnology

Background:

  • Fabricating nanofibers from polymers with limited spinnability, such as m-poly(hydroxyamide) (m-PHA), is challenging with conventional methods.
  • Traditional electrospinning often requires additives to induce fiber formation, which can alter material properties.

Purpose of the Study:

  • To explore a transient viscosity adjustment method for fabricating nanofibers from non-spinnable m-PHA.
  • To investigate the use of a coaxial nozzle and sheath-core configuration with tetrahydrofuran (THF) for nanofiber production.

Main Methods:

  • Utilized a coaxial nozzle setup with a sheath-core configuration.
  • Introduced tetrahydrofuran (THF) in the sheath to temporarily adjust the viscosity of the m-PHA core solution.
  • Employed Scanning Electron Microscopy (SEM) and rheological analyses to characterize the nanofibers and process.

Main Results:

  • Optimized sheath-to-core flow ratios and THF flow rates led to reduced particle formation and uniform nanofibers (180-190 nm diameter).
  • THF diffusion caused momentary solidification at the interface, promoting nanofiber formation without compromising m-PHA solubility.
  • Increased THF flow rate enhanced solidification and jet elongation, improving fiber uniformity.

Conclusions:

  • The coaxial electrospinning approach offers a viable pathway for producing nanofibers from polymers with limited spinnability.
  • This method avoids additives, preserving the inherent properties of the polymer.
  • Further optimization may lead to complete bead-free nanofibers, expanding applications in high-performance fields.
