“…The chemicals such as titanium tetra isopropoxide [Ti{OCH(CH 3 ) 2 } 4 ] along with n-heptane were purchased from Sigma-Aldrich for the synthesis process. Chemical reduction was the method followed here with the mixing of Ti{OCH(CH 3 ) 2 } 4 and n-heptane of 28.7 ml and 100 ml respectively, and these solutions were mechanically stirred for 120 min [31]. During the stirring process, distilled water of 7.8 ml was mixed slowly in it.…”

In this research, chemically synthesized titanium oxide (TiO 2) nano-powder was utilized for upgrading mechanical and vibrational applications of pineapple, banana and sisal fibers. The substitution of TiO 2 upto 3% enhanced the tensile, impact and flexural strength of pineapple/sisal, sisal/banana and banana/pineapple hybrid combinations. Irregular dispersion of nano-filler at 4% degrades the mechanical stability of bio-composites. Pineapple and sisal hybrid combinations with 3% TiO 2 filler has the highest natural frequency due to excellent surface contact with resin/hybrid natural fibers and filter/ resin interface making higher stiffness to the composites with improved natural frequency. Natural frequency and damping properties enhanced with nano-filler mixing. The factors such as frictional properties and energy dissipation at maximum strain area in the filler make increment in the damping nature of the natural composites. In the equal fiber weight% of 35, pineapple-based hybrid composites make better damping rate by the higher interface thickness and smaller diameter of pineapple fiber than other two fibers.

“…Different oxides have been coupled with graphene including MgO to enhance the interfacial bonding between graphene and magnesium substrates [237], praseodymium-decorated graphene for the protection of a magnesium AZ31 alloy [238], while silver nanoparticles have been combined with GO to give protective coatings with antibacterial activity [62,239,240]. Additional metals/oxides such as TiO 2 [241][242][243], ZnO [244][245][246], CeO 2 [247] and NiCo [248] have been coupled with graphene to enhance dispersion and corrosion protection. Moreover, antimony tin oxide powder has been mixed with graphene sheets and added to epoxy coatings to give protective coatings with conducting properties [249].…”

Corrosion is a naturally occurring phenomenon and there is continuous interest in the development of new and more protective coatings or films that can be employed to prevent or minimise corrosion. In this review the corrosion protection afforded by two-dimensional graphene is described and discussed. Following a short introduction to corrosion, the application of graphene in the formulation of coatings and films is introduced. Initially, reduced graphene oxide (rGO) and metallic like graphene layers are reviewed, highlighting the issues with galvanic corrosion. Then the more successful graphene oxide (GO), functionalised GO and polymer grafted GO-modified coatings are introduced, where the functionalisation and grafting are tailored to optimise dispersion of graphene fillers. This is followed by rGO coupled with zinc rich coatings or conducting polymers, GO combined with sol-gels, layered double hydroxides or metal organic frameworks as protective coatings, where again the dispersion of the graphene sheets becomes important in the design of protective coatings. The role of graphene in the photocathodic protection of metals and alloys is briefly introduced, while graphene-like emerging materials, such as hexagonal boron nitride, h-BN, and graphitic carbon nitride, g-C3N4, are then highlighted.

“…However, the quality of GO may be degraded due to surface defects during the oxidation process. Hence, several additives, such as silica, octadecyl amine, isocyanate, MnO 2 or TiO 2 , can modify the covalent bonds of GO, thereby reducing the interactions between GO molecules to increase dispersibility and improve surface defects 21–24 …”

To enhance the anti‐corrosion of the waterborne epoxy resin coating, we filled GO‐TiO2 into the coating with ultrasound and stirring method. Results show that coatings rendered optimum properties at GO‐TiO2 content of 0.4 wt% with a hardness of 3H and rate of thermal weight loss reduce 8.3 wt%. After immersion for 30 days, coating exhibited water absorption ratio of merely 11.25% and open circuit potential of −0.871 V. After 1000 h of scratch‐neutral salt spray test, no obvious signs of corrosion were observed on surface. Moreover, Electrochemical results demonstrated that maximum impedance modulus of 0.4GO‐TiO2 coating was 2.18 × 106 Ω cm2, corresponding to superior corrosion resistance. What is more, anticorrosion mechanism was discussed. In conclusion, Filling GO‐TiO2 improved mechanical properties, thermal stability and corrosion resistance of waterborne epoxy resin coatings.
