We found that hydrogels with one-component-rich segments are mechanically stronger than those with adjacent-rich monomer sequences in water, while hydrogels with a rich cation-π adjacent sequence showed excellent mechanical strength and underwater adhesion in saltwater (0.7 M NaCl). The molecular mechanisms for these behaviors are discussed in terms of polymer structures. This work reveals the importance of monomeric sequences in determining hydrogel properties and provides a facile approach to develop hydrogels with different properties but the same monomer composition.Science China Press2021-08-12engjournal articleAMhttp://hdl.handle.net/2115/86544https://doi.org/10.1007/s11426-021-1010-31674-72911869-1870SCIENCE CHINA Chemistry64915601568https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/86544/2/Supporting%20information.pdfapplication/pdf337.59 KB2021-08-12https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/86544/1/manuscript.pdfapplication/pdf1.36 MB2021-08-12
