Wang, Jiarong; Guo, Mingyu published the artcile< Thermo-responsive, mechanically robust and 3D printable supramolecular hydrogels>, Reference of 112-63-0, the main research area is three dimensional supramol hydrogel.
In this work, poly(N-isopropylacrylamide) (PNIPAm) grafted and multi-urea linkage segmented linear polyurethane-urea (PUU) copolymers were synthesized using α-dihydroxyl terminated PNIPAm as a chain extender and water as an indirect chain extender, resp. A series of PUU supramol. hydrogels were then easily obtained by solution casting and then water swelling of these PUU copolymers. These PUU supramol. hydrogels show not only thermo-responsive surface wettability, but also robust mech. performance with tensile strength and elongation at break of 0.2-2.9 MPa and 1100-3000%, resp., at 37°C. In addition, temperature responsive and mech. strong 3D hydrogel scaffolds were also developed by a direct-write 3D printing technique using a methanol solution of the PUU copolymer as the ink. These supramol. hydrogels are expected to be used as functional biomaterials, especially as elastic substrates for cell sheet cultures under dynamic mech. stimulation.
