Due to an increasing trend of size diminution, integration, and multifunctionality, the heat load on electronic devices is constantly increasing. Though nucleate boiling is regarded to be the most efficient mode of heat transfer, it still has much room for improvement in terms of heat transfer coefficient and critical heat flux. Thus, extensive research efforts have been devoted to the preparation of functional heating surfaces for enhanced boiling. This study presents nucleate boiling enhancement on a 3D porous graphene oxide/silver nanowire hybrid film. Then, boiling experiments were conducted under atmospheric pressure using a custom-developed boiling apparatus with a flat copper heating surface. Bubble-induced graphene oxide/silver nanowire hybrid deposition structures were analyzed through a series of characterizations such as Field Emission Scanning Electron Microscopy, Energy Dispersive X-Ray Spectroscopy, profilometry, and contact angle analysis to elaborate the physical mechanism behind the nucleate boiling enhancement. Among three tested concentration ratios (GO:AgNW; 0:1, 1:1, 1:5 by weight), maximum heat transfer coefficient and critical heat flux enhancement were achieved at a GO:AgNW concentration ratio of 1:5 owing to the improved surface characteristics such as surface area, bubble nucleation site density, lateral heat conduction, and capillarity. Heat transfer coefficient and critical heat flux enhancements of graphene oxide/silver nanowire hybrid surface reached 196.6% and 182.4%, while the upgrades on graphene oxide surface were 112.4% and 135.3%, respectively.

由于尺寸减小、集成化和多功能化的趋势不断增加，电子设备的热负荷不断增加。虽然核沸腾被认为是最有效的传热方式，但在传热系数和临界热通量方面仍有很大的改进空间。因此，广泛的研究工作致力于制备功能性加热表面以增强沸腾。本研究提出了 3D 多孔氧化石墨烯/银纳米线混合膜上的核沸腾增强。然后，使用定制开发的具有扁平铜加热表面的沸腾设备在大气压下进行沸腾实验。通过场发射扫描电子显微镜、能量色散X射线光谱、轮廓测量和接触角分析等一系列表征分析了气泡诱导的氧化石墨烯/银纳米线混合沉积结构，以阐述核沸腾增强背后的物理机制。在三个测试的浓度比（GO：AgNW；按重量计 0：1、1：1、1：5）中，在 GO：AgNW 浓度比为 1：5 时实现了最大传热系数和临界热通量增强，这是由于改进的表面特性，例如表面积、气泡成核位置密度、横向热传导和毛细作用。氧化石墨烯/银纳米线混合表面的传热系数和临界热通量增强分别达到196.6%和182.4%，
