Mos₂ additives for enhancing tribological performance of Hydroxypropyl methylcellulose biopolymer

This study demonstrates the influence of MoS₂ additives on the tribological performance of Hydroxypropyl methylcellulose composite films. Biopolymers have numerous potential applications, as they can be relatively quick and easily prepared and possess characteristics that are easy to optimize. The tribological characteristics of composite films can be enhanced by controlling the thickness of the film and by adding MoS₂ particles. An appropriate film thickness can optimize the tribological characteristics and service life of the film. MoS₂ nanoparticle additives can alter the surface morphology of a film, thus, affecting its tribological behavior. The addition of an appropriate quantity of MoS₂ can alter the surface roughness and load-carrying capacity of the film. The mechanism by which MoS₂ enhances the tribological characteristics of a composite film is dependent on the uniform dispersion of MoS₂ particles within the film and the optimization of the surface roughness of the film.
