Chinese research consortium develops conducting polymer composites for flexible electronics

A study team led by Xiaodong FANG from Anhui Institute of Optics and Fine Mechanics (AIOFM), Hefei Institutes of Physical Science, and Mingming MA at CAS’ University of Science and Technology of China (USTC), designed and synthesized a series of polyol-polypyrrole (polyol-PPy) composites. Doped with tetra-armed polyethylene glycol (PEE), the PEE-PPy film achieved a tensile strength as high as 125 MPa, and the elongation-at-break was about 75%. The tensile toughness was 73 MJ/m3, similar to natural cocoon silk (70 MJ/m3). Additionally, the PEE-PPy film had a conductivity of 115 S/cm.
