Abstract

The anticorrosion of metals has gain considerable interest in view of economic and environmental issues. Coating protection is one of the most effective and cost-effective methods for anticorrosion of metals. However, the traditional coatings often suffer from many issues such as poor performance or high cost. For the first time, a strategy was proposed by constructing cellulose nanofibrils (CNF)/alpha‑zirconium phosphate (α-ZrP) composite as nanofiller and incorporating into water-based coatings for anticorrosion of metals. The successful coordination of α-ZrP nanosheet and CNF were characterized. The effects of the resultant composite on anticorrosion performance were investigated. The results showed that, the as-prepared coating exhibited superior anticorrosion performance to commercial coatings. The impedance of the test sample coated with the as-prepared coating reached up to 4.38 × 105 Ω when it was immersed in 3.5 % NaCl solution with few corrosions fragmentation on metal surface, exhibiting a favorable long-term anticorrosion performance. Meanwhile, the anticorrosion mechanism was proposed. It is expected that this strategy would provide novel solutions for developing highly efficient water-based anticorrosive coatings of metals.
