Material preparations and rheological measurements of hydrogel inks. (A) Schematic illustration of the synthesis process of PVA/TA/PAA hydrogel inks. (B) The sample preparation of different mass ratios of PVA and TA (no TA, 1:0.5, 1:1, and 1:2). The scale bar is 5 mm. (C) Viscosity as a function of shear rate. (D) Storage modulus (G′) and loss modulus (G″) as a function of temperature. (E) Swelling ratio of printed PVA/TA/PAA hydrogel inks in DI water.
