Protection of metal is primary undertaking for any design engineer and coating formulator. Construction of large scale equipment and structure involves huge investment in terms of money, time, manpower and other resources. In economic aspects, the life of such structure must as long as possible to get the best return on its investment. To improve the life of such huge structures, it is becomes mandatory to protect the metal substrates from corrosion. Application of corrosion resistant coating is one of the most intriguing, robust, practical and efficient techniques to safeguard the metal from corrosion. Graphene is novel material and got prodigious application due to its extraordinary features. Lot of research has been conducted since last decade for modifying the graphene and making the best use to formulate corrosion resistant coating. The use of graphene in the coating creates an obstacle and increases the convoluted path for corrosive medium to reach the metal. As the path to reach to metal is increased, it delays the corrosion medium to reach up to the metal and thus corrosion of metal can be avoided. In this literature review is conducted for various aspects of corrosion, importance of graphene in coating formulation is discussed, which includes chemical modifications of graphene, effect of graphene concentration on corrosion inhibition and contact angle of coating. This review also discussed about the importance of water based corrosion resistant coating to avoid the environmental damages. Keywords: Graphene, Corrosion resistance, contact angle, water base coating, metal protection, corrosive media, corrosion inhibition.

“…Owing to their significant flexibility in practical use, polymer composites containing magnetic particles are preferred for radar-absorbing technology [16]. Polymer matrix composites containing reinforced E-glass fibre facilitate the absorption of microwaves and offer high structural performance with the addition of lossy nanofillers [17][18][19]. Nickel-zinc ferrite (NZF) is a ceramic ferromagnetic material with a cubic-system crystalline structure.…”

The development of new radar-absorbing structures (RASs) with strong microwave absorption, fine thickness and adequate structural performance is imperative. Herein, nanocrystalline Ni 0.5 Zn 0.5 Fe 2 O 4 was synthesised by a facile and effective sol-gel autocombustion technique. The structural and magnetic properties of ferrite were determined by various characterisation techniques, and E-glass/epoxy-based nanocomposites with different weight percentages of ferrite were fabricated by in-situ polymerisation. Further, electromagnetic properties were investigated to elucidate the possible absorption mechanism of the fabricated structures. The 4-mm-thick double-layered E-glass/epoxy/nickel-zinc ferrite composites exhibited reflection loss (RL) of <−10 dB for a bandwidth of 2.4 GHz and a maximum RL of −33 dB at 9.6 GHz. This performance was attributed to the larger magnetic loss and sufficient matching of electromagnetic parameters. This study provides a unique insight into the utilisation of Ni 0.5 Zn 0.5 Fe 2 O 4 for producing lightweight and relatively thin RASs in the X-band at a low cost.

A novel radar absorbing material was developed on nonwoven fabric using BaFe12O19/multi-walled carbon nanotube, which was synthesized by combustive sol–gel technique. The functional carboxylated multi-walled carbon nanotube was utilized in silicon matrix and printed on fabric surface to enhance the intensity and band width of wave absorption. The crystalline structure, morphology, and magnetic properties were characterized by X-ray diffraction, field emission scanning electron microscope, and vibrating sample magnetometer. The maximum reflection loss of nanoparticles was measured about −7 dB on 9.5 GHz. Moreover, the maximum absorption in X band was close to −38.45 dB in 10.5 GHz at the thickness of 1.5 mm with bandwidth of 2.6 GHz. Moreover, in Ku band, the maximum absorption for BaFe12O19/multi-walled carbon nanotube sample with thickness of 1.5 mm was reported as −31.38 dB, which was recorded on 15.9 GHz with 3.2 GHz bandwidth. Interestingly, the fabric coated with bare BaFe12O19 nanoparticle exhibits a maximum absorption of −3.5 dB at 9.7 GHz, which is lower compared to the absorption value of −17.8 dB at 9.8 GHZ for the fabric coated with BaFe12O19/multi-walled carbon nanotube. However, in Ku band, the fabric coated with BaFe12O19 nanoparticles shows lower value of −2.4 dB compared to X band in 17.6 GHz. In comparison, for composite nanoparticles coated sample, a nearly similar maximum value of −17.6 dB was recorded on 16.7 GHz with band width of 2.2 GHz. Results indicate appreciable maximum absorption value of more than 90% in X and Ku band, which can be attributed to presence of carbon structure in composite material.
