A team of researchers in the US (SUNY Buffalo, Temple University) inspired by kirigami used nanoconfinement engineering and strain engineering to create tiny sheets of strong yet bendable electronic materials made of a polymer, PthTFB. The nanosheets can be stretched up to 2000% with simultaneously high electrical conductivity, show remarkable electronic and mechanical reversibility and reproducibility under more than 1000 cycle. The conductivity of the nanosheets increases by three orders of magnitude due to the charge‐transfer complex formation between polymer chain and halogen, while the electrical conductance can be maintained over the entire strain regime. The research could lead to improvements in smart clothing, electronic skin and other applications that require pliable circuitry…read more. TECHNICAL ARTICLE
