Versatile Hydrogel Based on a Controlled Microphase-Separation Strategy for Both Liquid- and Solid-Phase 3D Printing.

ABSTRACT: Hydrogels are considered indispensable materials for fabricating flexible devices with their excellent flexibility and workability. To efficiently transform hydrogels into flexible devices, three-dimensional printing technology offers a powerful approach. However, hydrogels suitable for a single printing strategy have proven inadequate for fabricating flexible integrated devices. Herein, we report a simple and two-phase 3D-printed hydrogel (TP-3DPgel) achieved through a controlled microphase-separation strategy. The microphase-separation regions can undergo reversible changes through pH adjustment, giving TP-3DPgel an extremely broad viscosity tuning range from liquid to solid states. This overcomes limitations imposed by extreme rheological properties in different 3D printing processes, m
