Abstract

Herein, high thermal conductivity and good lubrication paraffin based nanofluid containing boron nitride nanoplatelets (BNNP) were prepared by ultrasonication method. The BNNP prepared by chemical assisted ball milling with size ranging from 400 nm to 1 µm were dispersed in paraffin oil to obtain nanofluid. The thermal conductivity of nanofluids is much improved compared to paraffin oil and paraffin oil containing as-received hexagonal boron nitride (hBN). Besides, the nanofluid containing 0.1 % BNNP exhibited an enhancement in lubricant with 71 % reduction in coefficient of friction compared to paraffin. This is attributed to the good lubricant, nanosizes of BNNP compared to as-received hBN.

含氮化硼纳米片石蜡基纳米流体的制备、热性能和润滑性能

采用超声法制备了含氮化硼纳米片（BNNP）的高导热、良好润滑的石蜡基纳米流体。将化学辅助球磨法制备的粒径为400 nm ~ 1µm的BNNP分散在石蜡油中得到纳米流体。与石蜡油和含六方氮化硼（hBN）的石蜡油相比，纳米流体的导热性有了很大的提高。此外，与石蜡相比，含有0.1% BNNP的纳米流体在润滑方面表现出增强作用，摩擦系数降低了71%。这是由于BNNP与接收的hBN相比具有良好的纳米级润滑剂。
