抄録

Tough triblock copolymer hydrogels with microstructures of sphere, cylinder, and laminae were constructed using a newly developed “drying and swelling” method without changing the chemical structures of their monomeric units. These tough triblock copolymer hydrogels commonly showed high fracture stress of ∼10 MPa but exhibited varied elastic moduli depending on their microstructures. Furthermore, the constructed laminar gel formed pH-sensitive photonic gel at the base conditions, providing the gel application with potential as a sensor. Given their high toughness, biocompatibility, and tunable modulus, this study helps expand the potential application of amphiphilic block copolymer hydrogels for medical and industrial use.
