Charge-driven interaction for adsorptive removal of organic dyes using ionic liquid-modified graphene oxide

Kanika Gupta et al.

Summary: A facile method of synthesizing GO-ImOH hybrid material has been presented for efficient removal of cationic dyes. The GO-ImOH exhibited higher adsorption capacity for cationic dyes compared to GO adsorbent, with multiple adsorptive interaction pathways identified between the adsorbent and dye molecules. The work opens up a new direction for the development of ionic liquids-modified 2D nanomaterials for rapid and effective removal of organic pollutants.

Smart PANI/epoxy anti-corrosive coating for protection of carbon steel in sea water

Ahmad Diraki et al.

Summary: The study found that by electrochemically synthesizing SC and SDS-doped polyaniline coating directly on the surface of carbon steel, and then covering it with a commercial epoxy layer, efficient corrosion protection of carbon steel can be achieved. This dual-layer coating can quickly recover its anticorrosive properties after being scratched, and maintain stability.

Oligomeric ethylene-glycol brush functionalized graphene oxide with exceptional interfacial properties for versatile applications

Rui Liu et al.

Summary: This research focuses on improving the dispersion of graphene oxide (GO) to prepare a highly anisotropic GO material (GOC) that can disperse well in various organic solvents and maintain high dispersion stability in strong brine. The GOC can significantly reduce surface tension, generate water-in-oil Pickering emulsions with high water content, and exhibit liquid crystal behavior at the oil-water interface without external stimuli.

Preparation of graphene oxide-boron nitride hybrid to reinforce the corrosion protection coating

Xiaoling Liu et al.

Summary: In this study, coatings based on a graphene oxide-boron nitride/epoxy (GO-BN/EP) system were fabricated and applied for corrosion protection of metal substrates. The GO-BN hybrid sheet, with higher lipophilicity than GO and BN, showed excellent dispersibility in epoxy coating and outstanding barrier properties for corrosive ions in a 3.5 wt% NaCl solution. This research presents an innovative method for synthesizing GO-BN hybrid for corrosion protection applications.

Nano-scale P, Zn-codoped reduced-graphene oxide incorporated epoxy composite; synthesis, electronic-level DFT-D modeling, and anti-corrosion properties

Navid Keshmiri et al.

Summary: Recent research has highlighted the potential of advanced nanomaterials such as graphene oxide as smart containers for controlled desorption of inhibitors and dual active/passive anti-corrosive agents in polymeric composites. By chelating zinc cations with AMP on reduced graphene oxide, a nanocontainer with active protection potency was formed. Incorporation of these anti-corrosive nanocontainers into epoxy coatings significantly improved coating protection, with a protective AMP and zinc cation complex formed in scratched areas demonstrating self-healing anti-corrosion potency.
