Area of Science:

  • Materials Science
  • Nanotechnology
  • Polymer Science

Background:

  • Electrospinning is a versatile technique for creating polymer micro- and nanofibers.
  • Nanocomposites offer enhanced material properties compared to their bulk counterparts.
  • Developing advanced materials for humidity sensing is crucial for various technological applications.

Purpose of the Study:

  • To synthesize and characterize poly(lactic acid)/polyaniline-zinc oxide (PLA/PANI-ZnO) composite micro-fibers.
  • To investigate the structural, thermal, and morphological properties of the composite fibers.
  • To evaluate the humidity sensing performance of the developed composite fibers.

Main Methods:

  • Hydrothermal and in situ polymerization for PANI-ZnO nanocomposite synthesis.
  • Electrospinning for fabricating PLA/PANI-ZnO composite micro-fibers.
  • X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Differential Scanning Calorimetry (DSC) for material characterization.
  • Water contact angle measurements for surface hydrophilicity analysis.
  • Humidity sensing tests in the 20-90% relative humidity range.

Main Results:

  • PANI-ZnO nanocomposites with an average crystallite size of 36 nm were synthesized.
  • PLA/PANI-ZnO composite fibers exhibited a reduced average diameter (1.4 μm) compared to pure PLA fibers (2.5 μm).
  • Enhanced thermal properties were observed, with a melting temperature shift from 149.3 °C for pure PLA to 153.0 °C for the composite.
  • The composite fibers demonstrated good humidity sensing response (85 s) and recovery (120 s) times.

Conclusions:

  • The electrospinning of PLA/PANI-ZnO composite fibers is feasible and yields materials with improved properties.
  • The incorporation of PANI-ZnO nanoparticles enhances the thermal stability and humidity sensing capabilities of PLA fibers.
  • The 1D fiber structure significantly contributes to the enhanced humidity sensing performance, suggesting potential for sensor development.
