Despite strong demands in such applications and great progress in irreversible bonding of robust hydrogels to diverse synthetic and biological surfaces, tough hydrogels with fast, strong, and reversible underwater adhesion are still not available. Herein, a strategy to develop hydrogels demonstrating such characteristics by combining macroscale surface engineering and nanoscale dynamic bonds is proposed. Based on this strategy, excellent underwater adhesion performance of tough hydrogels with dynamic ionic and hydrogen bonds, on diverse substrates, including hard glasses, soft hydrogels, and biological tissues is obtained. The proposed strategy can be generalized to develop other soft materials with underwater adhesion.Wiley-BlackwellJournal Articleapplication/pdfapplication/pdfhttp://hdl.handle.net/2115/75191https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/75191/1/Manuscript-adma.201801884.pdfhttps://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/75191/2/Supplementary%20Information-adma.201801884.pdf0935-9648Advanced Materials303218018842018-08-09enginfo:pmid/29939425info:doi/10.1002/adma.201801884This is the peer reviewed version of the following article: Ping Rao Tao Lin Sun Liang Chen Riku Takahashi Gento Shinohara Hui Guo Daniel R.
