little is known about the influence of altered gravity on hydrogel properties. Here we study the mechanical properties of Poly (ethylene glycol) diacrylate (PEGDA) and PEGDA incorporated with graphene oxide (GO) by performing tensile tests in micro and hypergravity during a Parabolic flight campaign...
Radiation-induced polymerization and cross-linking method has been applied to hydrogel preparations for decades, but less attention has been paid to the mechanical properties of the hydrogels. In this work, we provide a systematic study on the mechanical properties of hydrogels synthesized with the ...
The mechanical properties of SA hydrogels can be significantly improved by incorporating HANWs. The maximum compressive modulus (E 50% ) and tensile Young's modulus of the hybrid hydrogel (HANWs/SA=2:1) are as high as 0.123MPa and 0.994MPa, which are about 162% and 614% those of the ...
Because of the crucial roles of time-dependent mechanical properties, fluid flow, and swelling properties on tissue and cell behavior, these findings highlight the need for greater consideration of the effects of the extrusion process on hydrogel properties. 展开 ...
The swelling and mechanical properties of a hydrogel based on the zwitterionic monomer N , N -dimethyl- N -methacryloyloxyethyl- N -(3-sulphopropyl)ammonium betaine crosslinked with ethylene glycol dimethacrylate have been determined as a function of temperature. The volumetric swelling has been found...
The tensile strength and dynamic modulus of PVA hydrogels increased upon annealing, irrespective of the degree of polymerization (DP) of PVA, but always at the sacrifice of the water content of hydrogel. In addition to the mechanical strength, the hardness of PVA hydrogels was improved by ...
For use in a range of applications, hydrogel properties are vital, but it can be challenging to balance different aspects. Here, the authors report the use of a dehydration strategy to prepare hydrogels with desirable fracture toughness, fatigue threshold, and modulus. ...
Interpreting the results of such studies requires accurate quantification of the mechanical properties of the hydrogel. There is significant variation in the reported mechanical properties of agarose hydrogels, and little is reported on the influence of factors associated with mixing these hydrogels with ...
To improve the mechanical properties of responsive polymer hydrogels, a novel polymer nanocomposite hydrogel ("polymer NC gel") consisting of a terpolymer of acrylamide (AM), acrylic acid (AA), and 2- 关键词: pH and temperature sensitivity Polymer nanocomposite hydrogel Mechanical properties Swelling...
In addition, this DHIR hydrogel exhibits reversible mechanical properties after undergoing cyclic loading and unloading. Interestingly, the DHIR hydrogels with appropriate compositions demonstrate temperature-tunable mechanical properties as well as accompanied shape memory effect. The dual noncovalent bonding ...
