ABSTRACT: Conductive hydrogels had demonstrated significant prospect in the
field of wearable devices. However, hydrogels suffer from a huge limitation of
freezing when the temperature falls below zero. Here, a novel conductive
organohydrogel was developed by introducing polyelectrolytes and glycerol into
hydrogels. The gel exhibited excellent elongation, self-healing, and self-adhesive
performance for various materials. Moreover, the gel could withstand a low
temperature of ?20 °C for 24 h without freezing and still maintain good
conductivity and self-healing properties. As a result, the sample could be applied for
motion detection and signal transmission. For example, it can respond to finger
movements and transmit network signals like network cables. Therefore, it was
envisioned that the effective design strategy for conductive organohydrogels with
antifreezing, toughness, self-healing, and self-adhesive properties would provide wide
applications of flexible wearable devices.
