Rational Construction of SiO₂/MoS₂/TiO₂ Composite Nanostructures for Anti‐Biofouling and Anti‐Corrosion Applications

Abstract

We have prepared MoS2/SiO2/TiO2 ternary heterojunction composite for the anti‐corrosion and anti‐fouling applications. The molybdenum disulfide (MoS2) adorned silica (SiO2) nanoparticles are synthesized through the wet chemical process. The prepared MoS2/SiO2 composites is subjected for dynamic light scattering (DLS) analysis to understand the particle size, then the X‐Ray diffraction (XRD) to determine the crystal structure and Field emission scanning electron microscopy (FE‐SEM) to characterize its morphology. The TiO2 nanoparticles are prepared through stober process. The prepared TiO2 nanoparticles along with MoS2/SiO2 composites are fused together in the natural resin for the construction of primary coating mixture (MoS2/SiO2/TiO2). The primary composite coating mixture is coated on the mild steel panels for the analysis. The contact angle analysis is done for the coated mild steel samples to get the insight on its hydrophobicity and the surface smoothness. Further, to perform the corrosion studies, the salt spray analysis is done on the mild steel panels. The MoS2/SiO2/TiO2 ternary heterojunction composite mixture performed well on the anti‐biofouling and anti‐corrosion investigation.

P‐16.5: Investigation on metal corrosion characterise and resistance of touch panel

“…Much research has been done about the way to improve the metal corrosion, but they only refer to one or two respects, such as adjusting the process parameters of metal targets, which is only referring to metal process [6] . Another is to add some highmolecular polymers to protect metals [7] . This article studies from the corrosion path and the OGM production process, systematically investigating on all the related influence factors of OGM products process: raw materials, coating process, surface sensor layers, protective film attachment treatment and water glue lamination to find the best solution for metal protection.…”

The development of surface treatments on galvanised steel products for the automotive industry utilising a chemcoater

“…a mild steel matrix was shown to be highly effective by combing MoS2 with a hybrid pigment, before adding it to a waterborne epoxy (112,113). Additionally, MoS2 nanotube coatings have a superb low frictional performance which is why they are ideal for anti-wear and extreme pressure components and are regularly used in machining and forming applications.…”
