Abstract
Corrosion is a widespread issue affecting many aspects of daily life. To further improve the anti-corrosion performance of nano-Ti polymer coatings from our previous research, graphene slurry is filled to modify nano-Ti epoxy resin coatings. The structure, anti-permeability, anti-corrosion, and anti-wear properties of nano-Ti polymer functional coatings with different graphene slurry were systemically investigated by field emission scanning microscopy (FE-SEM), Fourier transform infrared spectroscopy (FT-IR), immersion test, electrochemical measurements, and wear test. The FE-SEM results showed that graphene can be well dispersed in nano-Ti polymer coating when the graphene content is 0.5 wt%. Furthermore, the results showed that the addition of graphene can improve the anti-permeability, anti-corrosion, and anti-wear properties of nano-Ti polymer coatings. The water uptake of nano-Ti polymer/graphene functional coatings was reduced from 2.4 to 0.05%. The friction coefficient of the coatings also decreased from 0.53 to 0.22 due to the good dispersion of graphene slurry. The corrosion resistance of the functional coatings decreased with increasing graphene slurry. Nano-Ti polymer/graphene functional coatings showed optimal comprehensive performance and anti-corrosion performance as the graphene content was 0.5 wt%; the appropriate amount of graphene slurry can effectively improve the anti-corrosion performance of the nano-Ti polymer coating.
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
