Super-tough artificial nacre based on graphene oxide via synergistic interface interactions of - stacking and hydrogen bonding
نویسندگان
چکیده
Inspired by interfacial interactions of protein matrix and the crystal platelets in nacre, herein, a supertough artificial nacre was produced through constructing the synergistic interface interactions of p-p interaction and hydrogen bonding between graphene oxide (GO) nanosheets and sulfonated styreneethylene/butylene-styrene copolymer synthesized with multifunctional benzene. The resultant GObased artificial nacre showed super-high toughness of 15.3 ± 2.5 MJ/m3, superior to natural nacre and other GO-based nanocomposites. The ultra-tough property of the novel nacre was attributed to synergistic effect of p-p stacking interactions and hydrogen bonding. This bioinspired synergistic toughening strategy opens a new avenue for constructing high performance GO-based nanocomposites in the near
