摘 要: 根据多巴胺在碱性环境下自聚合的特性，利用Tris缓冲液和NaOH提供的碱性环境下制备了黑磷/聚多巴
胺(BP-PDA)纳米复合材料. 采用球盘摩擦试验仪以钢/钢为摩擦接触副，研究了BP-PDA作为大豆油润滑添加剂的
摩擦学性能. 结果表明：添加了质量分数为0.16%的BP-PDA分散油，其摩擦系数和磨痕宽度相比于大豆油分别降低
了约43%和52%. 通过对磨痕表面的成分和形貌特征的分析发现，在摩擦过程中的高接触压力和剪切作用下，大豆
油与BP-PDA发生摩擦化学反应形成复合摩擦膜，其主要由非晶碳、BP以及磷的碳氧化物组成，复合膜的形成使得
摩擦界面的摩擦磨损减小. 此外，对BP-PDA在大豆油中的分散情况进行了探究，发现其分散稳定性相比于BP，由
7天提升到20天. 此研究为生物质润滑油中的添加剂设计提供了思路，为揭示BP纳米复合材料在生物质润滑油中的
减摩抗磨机理提供了数据支持和理论指导.

Abstract: Surface modification is an important way to improve the dispersion stability and lubrication performance of
black phosphorus (BP) in lubricating base oils. In this paper, black phosphorus/polydopamine (BP-PDA)
nanocomposites were prepared based on the self-polymerization of dopamine in an alkaline environment provided by
Tris buffer and NaOH. The crystal structure, particle size distribution and physicochemical composition of the BP-PDA
composites were systematically analyzed using atomic force microscopy (AFM), scanning electron microscopy (SEM),
dynamic light scattering (DLS), X-ray diffraction (XRD), Raman spectroscopy (Raman) and X-ray photoelectron
spectroscopy (XPS). In addition, the tribological and dispersive properties of BP-PDA in soybean oil were investigated
using a UMT-TriboLabball-on-disk tribometer with steel/steel as the sliding contacting partner. The friction and wear
mechanism of BP-PDA composites in soybean oil was emphasized. Firstly, the effect of additives on friction properties
