Advanced Materials, Год журнала: 2021, Номер 33(42)

Опубликована: Сен. 3, 2021

Stretchable ionic conductors are appealing for tissue-like soft electronics, yet suffer from a tardy mechanoelectric response due to their poor modulation of conduction arising intrinsic homogeneous chain network. Here, highly robust ionotronic fiber is designed by synergizing liquid and crystal elastomer with alternate rigid mesogen units spacers, which shows an unprecedented strain-induced conductivity boost (≈103 times enhanced as stretched 2000% strain). Such surprisingly high enhancement attributed the formation microphase-separated low-tortuosity ion-conducting nanochannels guided emergence aligned smectic mesophases, thus allowing ultrafast ion transport that resembles role "swimming lanes." Intriguingly, boosting even reverses Pouillet's Law-dictated resistance increase at certain strains, leading unique waveform-discernible strain sensing. Moreover, retains thermal actuation properties maximum 70% changes upon heating, enables integrated self-perception actuation. The findings offer promising molecular engineering route mechanically modulate behavior toward advanced applications.
