“…However, many tissues such as muscle, ligament, cartilage and skin exhibit an excellent toughness, soness and mechanical properties. [6][7][8] The classic hydrogels deliver a poor mechanical performance because of the lack of efficient energy dissipation in their gel network; 9,10 resulting in limiting their applications as biomaterials in biological studies. Therefore, preparation of hydrogels with good mechanical properties is important.…”

“…When mixed with water, it easily dispersed and thoroughly emulsified (Figure B), and then formed a self‐standing hydrogel in 2–10 min at room temperature (Figure C,D). Different from previous reports, the preparation of the PU prepolymer was finished in a one‐step reaction using two different low‐cost polyols, and hydrogel was quickly formed when the prepolymer was mixed with water. The simplicity and high efficiency made this route more suitable for large‐scale synthesis of such hydrogels and application in industrial and medical fields.…”

“…For example, for those PU hydrogels with good mechanical properties, the water content in them usually was below 70% (in mass). Guo and co‐workers developed a polyacrylamide‐based PU hydrogel with maximum water content up to 90%, but the tensile properties were very poor (tensile strength: 40 KPa; elongation: 560%) . Gu and Mather reported a water‐triggered thermoplastic PU hydrogel with better mechanical strength, but the water content was only up to 65% and the elongation was 735% .…”

In this study, a very simple, scalable, and low‐cost one‐step recipe is presented for preparing a biodegradable polyurethane prepolymer composed of isocyanate terminated linear polyethylene glycol and isocyanate terminated four‐armed polycaprolactone. Then, the corresponding hydrogels are easily formed by mixing the prepolymer with water in few minutes. The resulting hydrogel shows excellent mechanical properties with high tensile strength (up to 233.6 KPa) and recorded elongation rate (5000%), while maintaining high water content (up to 91% mass ratio). Meanwhile, the maximum water retaining capacity of the hydrogel can be up to 40 times of polyurethane prepolymer (in mass), which is equal to 97.6% water content. In addition, the degradation properties of the obtained hydrogel are studied in detail. This study demonstrates a facile approach to prepare the hydrogel with both excellent mechanical properties and high water content, which marks it as a potential candidate for applications in agrological field, such as sand fixing in desertification control.

“…However, the hydrogels become fragile and do not exhibit initial mechanical performance because of the removal of the surfactant from the gel when immersed in a large amount of pure water . Highly stretchable and resilient hydrogels without surfactant were prepared by the free‐radical copolymerization of acrylamide and polymerizable amphiphilic polyurethane (PU) macromolecules in 2013 . The polymerizable amphiphilic PU macromolecule was synthesized by the introduction of hydrophilic EO (ethoxylate) chains into PU and then reacted with 2‐isocyanatoethyl acrylate.…”

Hydrophobic association hydrogels (HA gels) have been proven to be one of the most popular research interests in physically crosslinking hydrogels. Meanwhile, the association mode of hydrophobic monomers and the structure of the hydrophobic microdomain is crucial to their mechanical properties. In this study, we designed high‐performance complex HA gels by novel complex micelles and acrylamide without small‐molecule surfactants. The complex micelles were prepared by a simple complex of two polymerizable amphiphilic dodecanol polyoxyethylene (n) acrylate monomers (alcohol ethoxylate (n)‐acryloyl chloride, AEO‐3‐AC, AEO‐23‐AC). The coordination effect between these amphiphilic monomers with a large hydrophilic difference greatly improved the strength of the gels. The mechanical properties, including the breaking elongation ratio and tensile strength, could be easily adjusted through the variation of the complex ratio in a relatively broad range. The mechanical strength of the resulting hydrogels with composite micelles were improved almost 200% over those of the hydrogels having either AEO‐3–AC or AEO‐23–AC. Dynamic light scattering and transmission electron microscopy testing revealed the sizes and morphologies of the complex hydrogels and their composite micelles. The discovery of the coordination provides a new route for preparing high‐performance hydrogels. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46400.
