Novel hydrogels that possess highly ordered anisotropic structures have been synthesized by controlling the diffusion direction of multivalent ions that act as cross‐linkers into a semi‐rigid polyelectrolyte solution. A double network (DN) technique is then used to form highly ordered DN gels with excellent mechanical properties, e.g., an extensibility of over 2200% the original length under uniaxial elongation.
