研究了颗粒组成、颗粒形状和氧化温度对导电胶电性能的影响。将具有球形和片状颗粒的银涂覆的铜粉和未涂覆的铜粉在诸如30、175、240、300°C和350°C的温度下氧化2小时并分散在环氧树脂基质中。本研究的结果表明，导电粘合剂的电性能受到颗粒组成和氧化温度的强烈影响，并且仅受颗粒形状的轻微影响。镀银铜粉比未镀银铜粉具有更高的抗氧化性。为了了解镀银铜粉如何表现出这种抗氧化性，通过热重分析（TGA）、X射线衍射（XRD）和俄歇光谱技术对其进行分析，以观察金属氧化物如AgO、Cu 2 O和CuO如何影响导电粘合剂的电性能。© 2004 Wiley Periodicals，Inc.应用聚合物科学杂志93：2045-2053，2004
The effects of particle compositions, particle shapes, and oxidation temperatures on the electrical properties of conductive adhesives have been investigated. Silver-coated copper powders and uncoated copper powders with spherical and flake-shaped particles are oxidized at temperatures such as 30, 175, 240, 300°C and 350°C for 2 h and dispersed in an epoxy matrix. The results of this study indicate that the electrical properties of the conductive adhesives are strongly affected by the particle compositions and oxidation temperatures and only slightly affected by the particle shapes. Silver-coated copper powders show significantly greater oxidation resistance than uncoated copper powders. To understand how silver-coated copper powders show such oxidation resistance, they are analyzed by the techniques of thermogravimetric analysis (TGA), X-ray diffraction (XRD), and Auger spectroscopy to observe how metal oxides such as AgO, Cu2O, and CuO affect the electrical properties of the conductive adhesives. © 2004 Wiley Periodicals, Inc.
