Tribological performance of the graphene synthesized from fruit cover plastic waste and oil palm fiber using a CVD method

Abstract

Purpose This paper aims to examine the friction and wear performance of the graphene synthesized from fruit cover plastic waste and oil palm fiber (OPF). Design/methodology/approach The graphene was synthesized by using a chemical vapor deposition method, where a copper sheet was used as the substrate. The dry sliding test was performed by using a micro ball-on-disc tribometer at various sliding speeds and applied loads. Findings The results show that both as-grown graphenes decrease the coefficient of friction significantly. Likewise, the wear rate is also lower at higher sliding speed and applied load. For this study, OPF is proposed as the best solid carbon source for synthesizing the graphene. Originality/value The main contribution of this study is opening a new perspective on the potentials of producing graphene from solid waste materials and its effect on the tribological performance.

Lubricity performance of hydrogen-free CVD growth of graphene on copper particles as an additive in paraffin base oil

“…OPF is an agricultural waste product, and its use as a precursor is environmentally friendly and sustainable. 20 This aligns with the principles of green and renewable materials for graphene synthesis. PS, while derived from petrochemicals, is widely available and can be recycled, reducing the environmental impact compared to single-use plastics.…”

A review of advances in tribology in 2020–2021

“…Graphene or graphene derivatives have a significant effect of reducing friction and wear of the composites [143] with different contents, as well as in other friction pairs such as steels, ceramics, and alloys [144]. The lubrication mechanism is mainly attributed to the fact that graphene or graphene derivatives enter the contact area to form a friction protective film, which reduces wear and reduces friction significantly due to the weak interlayer force of graphene nanosheets.…”
