摘要

银片广泛用作导电胶粘剂(ECAs)的填料。银片需要用有机润滑剂进行预处理，以确保ECAs具有适当的流变性。银片上的润滑剂影响ECAs的流变性、导电性和其他性能。用x射线光电子能谱法研究了银片的表面组成。利用漫反射红外光谱研究了银片表面润滑剂的性质以及润滑剂与银片表面的相互作用。用差示扫描量热法研究了润滑油的热分解过程。此外，还研究了一些化合物对润滑油去除的影响。

A fundamental study on silver flakes for conductive adhesives

Silver (Ag) flakes are widely used as fillers for electrically conductive adhesives (ECAs). The Ag flakes need to be pretreated with organic lubricants to ensure the proper rheology of the ECAs. Lubricants on the Ag flakes influence rheology, conductivity and other properties of ECAs. The surface composition of a Ag flake was investigated by X-ray photoelectron spectroscopy. The nature of the lubricant on a Ag flake and the interaction between the lubricant and Ag flake surface were studied by diffuse reflectance infrared spectroscopy. Thermal decomposition of the lubricant was also studied by differential scanning calorimetry. In addition, the effects of some chemical compounds on lubricant removal were also investigated.
