导电油墨起源于导电涂料,印刷电子行业的兴起产生了对导电油墨的研发需求。本文综述了碳系导电油墨填料的研究现状、导电机理、应用前景及其发展方向。首先概述了传统碳系导电油墨填料(石墨、炭黑、碳纤维及其混合物)以及新型碳系导电油墨填料(碳纳米管、石墨烯)的研究进展,重点分析了传统碳系填料的研究方向及手段,解释了新型碳系填料应用于导电油墨的优越性。然后从宏观和微观层面概述了当前主流的几种导电机理的基本原理和适用范围,并指出了目前对油墨导电性能的研究只能定性分析而不能定量描述的局限性。最后,重点介绍了两种新型碳系导电油墨填料的最新研究进展和应用方向,特别指出了当前对碳纳米管和石墨烯填料的研究亟需解决的问题,总结了二者今后的研究重点和研究趋势。 相似文献

On the basis of an analysis of results presented in the literature, the currently existing knowledge about relationships between the microstructural and physical properties of hard coatings is discussed. Particular emphasis is placed on the role of microstructural features, such as grain boundaries, nonequilibrium structures, impurities, and texture, in controlling the film hardness. On the basis of an analysis of results presented in the literature, the currently existing knowledge of electrically conductive adhesives (ECAs) is discussed. Particular focus is placed on the results obtained with ECAs that contain carbon nanotubes (CNTs) as conductive fillers. The review is divided in curable ECAs based on epoxy resins, and noncurable conductive hot melts and pressure‐sensitive adhesives based on thermoplastic polymers. More literature results were found for epoxy/conductive filler ECAs than for other adhesives. Confirming the assessments made in a book by Li et al., which refers to nanotechnologies in ECAs, we found that only a reduced number of articles allude to polymer/CNT ECAs. Our analysis of the results includes a study of the balance between the viscosity, immediate adhesion, solidification process, electrical conductivity, and mechanical properties of the adhesives. © 2013 Wiley Periodicals, Inc.
