Self‐Healing Hydrogel of Poly (vinyl alcohol)/Agarose with Robust Mechanical Property

Abstract: As promising soft materials, various excellent properties of hydrogels have received widespread attention during recent years. Mechanical properties and self‐healing performance are required characteristics for hydrogels in practical applications. An important challenge is to develop hydrogels exhibiting mechanical performance and self‐recoverability through physical cross‐linking. In this work, the authors report a hydrogel consisting of a fully physically linked poly (vinyl alcohol)/agarose (PVA/AG) dual‐net… Show more

“…A,B) Plots of the compressive versus tensile strength and modulus for BC–PVA–PAMPS (this work) and other strong hydrogels (see Table S1 in the Supporting Information for data and references). [ 13–35 ] The multiple data points for BC–PVA–PAMPS are for different compositions. C) BC–PVA–PAMPS easily bears the weight of a 100 lb.…”

“…The PLA layers (integrated into the FE numerical simulation models) were supposed to develop linear elasticity. The stress–strain engineering and elastic modulus relationship, which is dependent on the experimental test samples and the Poisson ratio = 0.36, was used [ 35 , 36 , 37 , 38 , 39 ]. Tensile sample dimensions, various structures, and opening shapes were prepared according to a standardized sample PLA sheet [ 30 ], as represented in Figure 2 .…”

“…Three dimensional network heterogeneity and lack of an effective energy dissipation mechanism are the main reasons for poor mechanical properties of hydrogels. [15][16][17][18] Recently, various strategies have been developed and utilized for preparing the high-strength PVA hydrogels, including nanocomposite hydrogels, 19,20 multi-network hydrogels, 21,22 and interpenetrating network hydrogels. 15,[23][24][25] Besides these strategies, mechanical properties of PVA-based hydrogels could also be improved by the freeze-thaw process.…”
