将层层自组装(LBL)技术与原位还原过程相结合在单晶硅片表面成功构筑了与基底结合牢固、性能优异的氧化锆/还原氧化石墨烯(ZrO2/rGO)多层纳米复合薄膜.试验中,引入了具有强附着性和还原性的物质-多巴胺,使得氧化石墨烯(GO)片的表面锚固和原位还原可以一步完成.另外,ZrO2粒子的表面组装通过简单、温和的溶液沉积过程来实现.结果证明:复合薄膜中rGO和ZrO2的引入以及多层结构的构筑赋予复合薄膜许多优异的性能.在不进行热处理的情况下,所构筑的ZrO2/rGO多层薄膜表现出优异的力学性能(硬度:11.54 GPa)和摩擦学性能(摩擦系数:0.12~0.17),可作为减摩抗磨涂层被用于微/纳机电系统(MEMS/NEMS)的表面保护和其他领域.
Combining layer-by-layer assembly (LBL) technology and in-situ reduction process, a series of ZrO2 / rGO multilayer nanocomposite films In the experiment, dopamine was introduced into the surface of the graphene oxide (GO) wafer to anchor and in situ reduction of the graphene oxide (GO) wafer.In addition, the surface of the ZrO2 particles was assembled by a simple and mild solution Deposition process.It is proved that the introduction of rGO and ZrO2 into the composite film and the construction of multi-layer structure confer many excellent properties on the composite film.The ZrO2 / rGO multilayers show excellent performance without heat treatment (Hardness: 11.54 GPa) and tribological properties (coefficient of friction: 0.12 ~ 0.17). It can be used as anti-friction and anti-friction coating in the surface protection of MEMS / NEMS and other fields.
