| 英文摘要 | Nacre-inspired coatings reinforced with amino-functionalized boron nitride nanosheets (NH2-BNNSs) were developed in this work. A hierarchical "brick and mortar" structure, where NH2-BNNSs act as "bricks" and epoxy resin act as "mortar", was developed attributed to electrostatic repulsion between NH2-BNNSs modified by sodium carboxymethyl cellulose. In nacre-inspired coatings, penetration path of corrosive species must travel to reach metal surface was extended significantly, leading to hindered metal corrosion. Electrochemical impedance spectroscopy demonstrated |Z|f=0.01 Hz of aluminum alloy (AA5052) covered by nacre-inspired coating (NC-20) was 4 orders of magnitude higher than that of AA5052 covered by pure epoxy coating after 84 days of exposure in NaCl solution. |
