Strong Bioinspired Polymer Hydrogel with Tunable Stiffness and Toughness for Mimicking the Extracellular Matrix
Inspired
by the delicate architecture of hyaline articular cartilage,
we report on a biomimetic polymer hydrogel that incorporates strong
intermolecular hydrogen bonding between urethane–urethane linkages
as well as urethane–ester linkages. The resultant hydrogel,
containing ≈75% water, can endure a compressive stress up to
56 MPa with a strain of 98%, and exhibit tunable compressive modulus
(0.19–1.38 MPa), as well as toughness (3629–28290 J
m<sup>–2</sup>) within a wide range. The tensile strength and
elastic modulus reach as high as 0.56 and 5.5 MPa, respectively. The
high stiffness and toughness enable the gel to withstand cyclic compressive
loadings without fracturing. Moreover, our hydrogel mimics the extracellular
matrices of cartilage and bone tissues and provides biochemical and
physical cues that support the three-dimensional proliferation of
chondrocytes and osteogenic differentiation of preosteoblasts
