“…If the concept is explained more precisely, the contact angle greater than 90 degree are less prone to hydrophobic effects thus making it less prone to corrosion. The development of super hydro phobicity is mainly attributed from the cumulative interactions of the highly cross-linked covalent bonding of printed circuit board powders on the metal surface and the water molecules [13].In this case 2 proportions produced results with contact angle greater than 90 degree. The most efficient coating observed is 1:2 mix, but for better workability and fluidity 1:3 mix is suggested because the difference in results of both the mixes is meager.…”

The growth in the industrial technology and communication sectors has enhanced the usage of electronic gadgets exponentially. Thus, it becomes highly essential to find new solution to utilize or dispose these e-wastes, in order to reduce the e-waste generation. Various reports mentioned that the major component of these e-wastes is their Printed Circuit Boards. Therefore, a new ideology is proposed to use these boards to produce a new coating with good corrosion resistance. At first the boards were separated from the discarded electronic appliances and various electrical elements were separated from these boards. Then the plain circuit boards are pulverized into fine particles and mixed with paint in 3 different proportions ranging from 1:4 to 1:2. The resulting mix was applied over the steel specimen and tested for corrosion resistance. The assessment was done in the aspects of contact angle, weight loss percentage, potentio dynamic polarization technique and electro chemical impedance spectroscopy. From the results it was clear that increase in the addition of printed circuit powder content in the corrosion proof paint coating enhanced the efficiency of the corrosion resistant behaviour 3.5 times than the specimen with uncoated steel specimens. This development of corrosion resistant behaviour of printed circuit powder was attributed from the inertness offered by the presence of silicon dioxides towards the corrosive fluids. Although, the coating of 1:2 proved to be optimum to protect the steel elements from the aggressive corrosion environment, by considering the workability aspects the 1:3 combination was suggested for the innovative development of anti-corrosion paint coating from the e-waste resources. HIGHLIGHTS Life cycles of every electronic wastes end with the hazardous challenging disposals Innovative utilizations of these electronic wastes for the corrosion resistant structural applications were detailed An anti corrosive coating for steel reinforcement was developed from the waste printed circuit boards Coating by printed circuit board powder enhanced 3.5 times more protection from the corrosion GRAPHICAL ABSTRACT

“…The most commonly used modifiers are silicon organic matter, such as the organosiloxane (KH-570), silicon acrylic emulsion, etc. Relevant research shows that the problem of flexibility and rust flash of modified potassium silicate coating can be effectively solved [34,35]. Also, the water-based inorganic zinc-rich coating modified by organosilicon has significant improvement in curing rate, salt spray resistance, mechanical properties and so on [36].…”

The interface properties of Fe(101)/zinc silicate modified by organo-siloxane (KH-570) was studied by using the method of molecular dynamics simulation. By calculating the temperature and energy fluctuation of equilibrium state, equilibrium concentration distribution, MSD of layer and different groups, and interaction energy of two interface models, the influencing mechanism on the interface properties of adding organosiloxane into coating system was studied at the atomic scale. It shows that the temperature and energy of interface oscillated in a small range and it was exited in a state of dynamic equilibrium within the initial simulation stage (t < 20 ps). It can be seen from the multiple peak states of concentration distribution that the iron substrate, organo-siloxane and zinc silicate are distributed in the form of a concentration gradient in the real environment. The rapid diffusion of free zinc powder in zinc silicate coating was the essential reason that affected the comprehensive properties of coating. The interface thickness decreased from 7.45 to 6.82 Å, the MSD of free zinc powder was effectively reduced, and the interfacial energy was increased from 104.667 to 347.158 kcal/mol after being modified by organo-siloxane.
