Fig. 1: Working mechanism of self-compliant ionic skin.
From: Self-compliant ionic skin by leveraging hierarchical hydrogen bond association
a Schematic dynamic compliance of viscous, elastic, and self-compliant ionic skins. b Typical rheological behavior and working mechanism of conventional supramolecular ionic skin with a homogeneously crosslinked structure. With decreasing frequency, the abrupt dissociation of physical interactions occurs leading to the sharp transition between viscous and elastic states. c Frequency-independent gel point state and working mechanism of self-compliant ionic skin with a hierarchically crosslinked structure. With decreasing frequency, the gradual dissociation of physical interactions takes place, resulting in simultaneous interchain breakup and enhanced entanglement as topological crosslink.
