Conductive elastomer is a stretchable elastomer that can possess ionic or electrical conductivity. However, its resistivity is exponentially increased when a small amount of strain changes are provided due to the irreversible internal deformation. Therefore, securing a wide range of linearity of the resistance-strain relation has been an important topic for preparing a highly reliable conductive elastomer. Herein, ionic conductive elastomer was prepared using 2-methoxyethyl acrylate and a molecular necklace-like polyrotaxane cross-linker to impart the reversible elastic properties. The MAPRX exhibited superior stretchability up to 1420% with a tensile strength of 0.52MPa. In addition, it could show wide range strain-resistance linearity (~1100%) due to the slidable supramolecular cross-linkers. Its linear sensitivity to the provided strain made it possible to be applied for the facile wearable strain sensors with good reproducibility. |
