(A) Schematic illustration of the synthesis of fatigue-resistant hydrogels with self-assembled PEDOT belts through in situ polymerisation in the double-network matrix. (a,b) A parent PAMPS double-network hydrogel is used to host the emulsion of 3,4-ethylenedioxythiophene (EDOT), which is redox polymerised within the DN gel channels, leading to the formation of an entangled PEDOT belt network. (c) Upon loading, the PAMPS network fractures into fragments linked by the ultralong PAAm chains, yielding a PE network interlacing with the rigid PEDOT belt mesh. (d) The PEDOT belts are composed of self-assemblies of PEDOT chains through π–π stacking. Reprinted (adapted) from [112]. Copyright (2014) American Chemical Society.
