Conventionally formed hydrogels lack mechanical strength and exhibit low tensile and compressive strength which hinders their extensive use as load‐bearing material. Interpenetrating polymer network systems are an effective strategy to toughen hydrogels. Yali Li, Chaoxia Wang, Wan Zhang, Yunjie Yin, and Qingqing Rao fabricate tough polyacrylamide/sodium alginate interpenetrating polymer network hydrogels with ionically crosslinked sodium alginate interpenetrated in covalently crosslinked polyacrylamide. Through the “one‐pot” method, the hydrogels presented high mechanical strength with excellent formability over conventional double network gels. The cover shows pictures of polyacrylamide/sodium alginate hydrogels with different shapes. (DOI: 10.1002/app.41342 )
