Mechanical and tribological properties of self-lubricating metal matrix nanocomposites reinforced by carbon nanotubes (CNTs) and graphene – A review

“…Graphene based materials provide high thermal conductivity enhancement as well as the advantage M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT of improving barrier properties in comparison with polymer matrix composites reinforced by CNTs [39,43]. Although, numerous polymer matrix nanocomposites reinforced by graphene nano-platelets and CNTs have been studied, still the challenge of adding nano carbonous materials into a metallic matrix and synthesize a fully uniform and dispersed structure is remained open to researchers [41,[44][45][46][47]. At the same time, another important processing issue in metal composite fabrication is the low interfacial strength between the CNTs and the matrix.…”

Physico–chemical and mechanical properties and antibacterial activity of silver/poly(vinyl alcohol)/graphene nanocomposites obtained by electrochemical method

“…There is growing interest in incorporating nanomaterials into polymer matrices to create antibacterial and biocompatible polymer nanocomposites for a wide range of applications, such as thin films for biosensors and biomedical devices, fibers for wound dressing, and dispersions with antimicrobial properties [15,16]. The addition of graphene, even at a very low concentration (usually less than 5%), into a polymer matrix can significantly improve the mechanical, thermal, electrical, and gas barrier properties of the polymer [17][18][19][20][21][22].…”

Optimization of mechanical properties of polypropylene/talc/graphene composites using response surface methodology

“…The reduction of the crystallinity in the presence of the fillers, possibly results from the polymer chains mobility being limited by the fillers which prevents crystal formation. Due to the role of the crystallites as crosslinks, the higher the crystallinity, the better the mechanical properties [27]. Considering that the crystallinity was reduced in the presence of the fillers, it can be concluded that the improvement in the mechanical properties of the composites results from the reinforcing effect of the fillers.…”
