Article Synopsis
  • An organic polymer composite made from polypyrrole and various additives has been developed to create a cost-effective, sensitive humidity sensor suitable for industrial applications, able to detect humidity levels from low to high.
  • The composite was synthesized using a chemical process and then treated at various temperatures; it was then characterized using techniques like FTIR, SEM, and DTA/TGA to evaluate its humidity-sensing capabilities.
  • The final sensor demonstrated impressive response times of 128 seconds at room temperature, showing excellent stability and repeatability across multiple cycles, making it a reliable option for humidity detection.

The promising chemical, mechanical, and electrical properties of silver from nano scale to bulk level make it useful to be used in a variety of applications in the biomedical and electronic fields. Recently, several methods have been proposed and applied for the small-scale and mass production of silver in the form of nanoparticles, nanowires, and nanofibers. In this research, we have proposed a novel method for the fabrication of silver nano fibers (AgNFs) that is environmentally friendly and can be easily deployed for large-scale production.
