In the harsh environment, the corrosion of Cu leads to the failure of pipelines, condenser, printed circuitboard and so forth. Thus, protecting Cu from corrosion is critically important from both science and engineeringbackgrounds. In this report, the hierarchical structure compositing dendritic Cu and ZIF-67 is preparedonto Cu by a two-step electrodeposition protocol. After thiol modification and oil infusion, bioinspiredsuperhydrophobic surface (SHS) and slippery liquid-infused porous surface (SLIPS) is respectivelyachieved, and sophisticated techniques are used for characterizing chemical composition, morphology,topology and wettability. Scanning Kelvin probe is employed to know the surface potentialdistribution before and after the biomimetic transformation. Using different electrochemical approaches,the corrosion inhibition effect is elucidated. In 3.5 wt% NaCl corrosive medium, |Z|0.01Hz of SLIPS is as highas 1.35 108 Xcm2 at the initial immersion stage. The value is remarkably enhanced compared with SHS(6.76 104 Xcm2) and bare Cu (8.74 103 Xcm2). After soaking for 168 h, |Z|0.01Hz value of SHS andSLIPS is 3.84 104 Xcm2 and 4.93 106 Xcm2, illustrating that SLIPS has high resistance to protectCu from corrosion.

Finding appropriate usage of waste printed circuit board (WPCB), a kind of electronic trash, is an importanttask from background of environment protection and waste management. Due to the intrinsic highhindrance barrier capability, recycled epoxy resin in rich source from WPCB gives opportunity for corrosionprotection of metals based on Two birds with one stone ideology. One stone in this ideology is to applywaste as resource, and two birds respectively indicate using PCB waste as valuable material and inhibitingmetal corrosion. In this paper, by combining biomimetics strategy, we adopt a three-step methodincluding anodic oxidation, hydrophobic treatment and infusion of composite containing epoxy resinfrom WPCB and dimethyl silicone oil to finally form WPCB based slippery liquid-infused porous surface(W-LIS). Morphology, composition, wettability and electrochemical properties are characterized bysophisticated techniques. Adding recycled hydrophobic/oleophilic epoxy resin from WPCB into oil phasecan effectively increase the barrier effect and raise anticorrosion ability. Moreover, W-LIS delivers antifreezingadhesion and biofouling inhibition property, which is obviously superior to LIS and lotus inspiredsuperhydrophobic (SHS) coating. The various excellent performances of W-LIS indicate epoxy resin fromwaste printed circuit board can act a versatile role in field of metal corrosion prevention.
