Overview

Demonstrates enhanced humidity sensitivity in a PANI/MWCNTs sensor, indicating promising applications for humidity detection.

Key Points

  • The aim is to develop a highly sensitive humidity sensor using a polyaniline and multiwalled carbon nanotube composite.
  • Fabrication of a PANI/MWCNTs composite sensor through in situ polymerization.
  • Electrical characterization to assess performance metrics including reproducibility and linearity.
  • Morphological analysis to examine the needle-like network structure of PANI on MWCNTs.
  • Sensor shows excellent reproducibility and high linearity with R² = 0.995.
  • Demonstrates low hysteresis of 6.9% relative humidity.
  • Maintains stability across a temperature range of 30.8–56.7 °C.
