Enhanced tribological properties of epoxy-based lubricating coatings using carbon nanotubes-ZnS hybrid

In this work, a facile and efficient method to overcome the poor dispersion of carbon nanotubes (CNTs) in the polymer matrix by in-situ synthetizing ZnS nanoparticles onto their surfaces was developed. The as-prepared CNTs/ZnS hybrid was then used as lubricating additive to enhance the friction-reducing and anti-wear properties of epoxy (EP) coatings. The microstructure and composition of CNTs/ZnS were characterized using HRTEM, FESEM, XRD, and...
