Abstract

The friction and wear of the worn surfaces is a principal cause of energy dissipation in automobile engines. The current study is supported with Graphene Nanoplatelets as an imminent material, also a carbon allotrope which has good thermal, physical, and chemical properties & Cellulose nanocrystals (CNCs) as a universal nano-sized ecological biopolymer. In view of this, the objective of the present work is to enhance the tribological behaviour and lubricant properties using hybrid Graphene nanoplatelets (GNPs) and Cellulose Nanocrystal (CNC) blended with SAE 40 having various concentrations in the range of 0.01% to 0.10%. The characterization is presented by different techniques such as X-ray diffractometer (XRD) and FESEM. The XRD patterns confirm the platelets structure of graphene nanoplatelets & Field emission scanning electron microscope (FESEM) showed the small and agglomerated particles range as 20-50 nm and 200 nm for GNPs and CNC respectively. The scanning electron microscope (SEM) geomorphology evaluation was conducted for all volumetric concentrations of single & hybrid nanolubricant. Morphological investigation indicates that there is homogeneous dispersion and there is a smoother surface after using Graphene:CNC nano lubricant compared to SAE 40.

石墨烯纳米片(GNPs) -纤维素纳米晶体(CNC)混合在SAE 40混合发动机润滑油中，用于汽车应用

磨损表面的摩擦磨损是汽车发动机能量耗散的主要原因。目前的研究得到了石墨烯纳米粒子作为一种即将到来的材料的支持，石墨烯纳米粒子也是一种具有良好热、物理和化学性能的碳同素异形体，纤维素纳米晶体（CNCs）是一种通用的纳米生态生物聚合物。鉴于此，本工作的目的是使用混合石墨烯纳米片（GNPs）和纤维素纳米晶体（CNC）与SAE40（浓度在0.01%至0.10%范围内）共混来增强摩擦学行为和润滑性能。通过X射线衍射仪（XRD）和FESEM等不同技术进行表征。XRD图谱证实了石墨烯纳米片晶的片晶结构。场发射扫描电子显微镜（FESEM）显示，小颗粒和团聚颗粒的范围为20-50 nm和200 nm。对所有体积浓度的单一和混合纳米润滑剂进行了扫描电子显微镜（SEM）形貌评估。形态研究表明，与SAE 40相比，使用石墨烯：CNC纳米润滑剂后，分散均匀，表面更光滑。
