Area of Science:

  • Materials Science
  • Nanotechnology
  • Polymer Science

Background:

  • Stretchable conductors are crucial for flexible electronics, implants, and soft robotics, demanding high conductivity at large strains.
  • Combining high conductivity and stretchability is challenging due to molecular mechanisms that reduce conductivity under strain.
  • Existing stretchable conductors often use high-aspect-ratio fillers, which present synthesis and processing challenges.

Purpose of the Study:

  • To develop novel stretchable conductors with high conductivity and stretchability using spherical nanoparticles.
  • To investigate the electronic tunability of mechanical properties in these nanocomposites.
  • To validate a modified percolation theory that accounts for nanoparticle self-assembly.
