Abstract: Organic materials are of great interest in various applications owing to their intrinsic designability, molecular controllability, ease of synthesis, and ecological sustainability. In this work, a facile and mild wet-chemical strategy was carried out to construct a conjugated Ni-BTA coordination polymer via the π-d hybridization with 1,2,4,5-benzenetetramine (BTA) as π-conjugated ligands and Ni2+ as metallic centers, which exhibits a unique two-dimensional nanosheet-like structure with available active sites, sufficient electrochemical activity, and multi-electron redox capability. On the one hand, the as-prepared Ni-BTA coordination polymer as electrode material exhibits a rapid, reversible, and efficient energy storage behavior with a large reversible capacity of 198 mA·h·g-1 at 1 A·g-1 and a high-rate capability of 150 mA·h·g-1 at 20 A·g-1 in alkali-ion aqueous electrolyte, which are further demonstrated by the in-situ Raman investigation. On the other hand, the Ni-BTA coordination polymer as anti-corrosion additive was introduced into the epoxy resin to achieve a Ni-BTA epoxy coating, which shows a long-term anti-corrosion performance with a low corrosion rate of 4.62×10-6 mm·a-1 and a high corrosion inhibition efficiency of 99.86%, suggesting its great engineering potential as the bi-functional organic material for high-performance energy storage and corrosion protection.
