Abstract

Abstract Printed electronics (PE) is one of the most dynamic technologies in the world. It proposes low-cost electronic network production in flexible substrates by numerous printing techniques, (screen printing, gravure, offset, flexographic, and inkjet printing), used in various industries. In PE, ink pigments are replaced by metallic particles or precursors that transmit electrical conductivity to the printed patterns such as carbon, polymers and conductive pigments. Conductive inks play an important role in printed electronics, and despite the number of conductive ink types available on the market, there are still issues to be addressed. Some of these restrictions include the use of toxic chemical reagents and solvents and complicated manufacturing protocols, which often make the industrialization of conductive inks an even more distant goal. In particular, conductive inks based on silver nanoparticles, Graphene and PEDOT:PSS are widely studied thanks to their high electrical conductivity. On the other hand, there is still work to be done to show the interest of inks based on phthalocyanine pigments, in particular copper phthalocyanine. Nevertheless, problems related to stability, dispersion and annealing temperature often limit the application of these four types of fillers. In this review, we present general information on available conductive fillers used for the formulation of conductive inks, focusing on metallic particles, carbon fillers, pigments and polymers. The influence and technical requirements of the regularly used printing techniques, as well as the post-processing treatments to achieve the targeted performance in the obtained inks have been discussed. In addition, the surface characteristics of the various types of extensible and flexible substrates used in portable electronics are described. Moreover, some types of printed flexible electronic components as well as notable applications of electronic textiles in various sectors are exhibited. Next, the major challenges for the manufacturing of printed flexible electronics and recommendations for future research are discussed in this review
电子纺织品上可印刷导电油墨的配方:综述
摘要印刷电子技术是世界上最具活力的技术之一。它提出了通过多种印刷技术(丝网印刷、凹版印刷、胶印、柔性版印刷和喷墨印刷)在柔性基板上进行低成本电子网络生产,这些技术用于各种行业。在PE中,油墨颜料被金属颗粒或前体取代,金属颗粒或前驱体将导电性传递到印刷图案,如碳、聚合物和导电颜料。导电油墨在印刷电子产品中发挥着重要作用,尽管市场上有很多导电油墨类型,但仍有一些问题需要解决。其中一些限制包括使用有毒化学试剂和溶剂,以及复杂的制造协议,这往往使导电油墨的工业化成为一个更遥远的目标。特别是,基于银纳米颗粒、石墨烯和PEDOT:PSS的导电油墨由于其高导电性而被广泛研究。另一方面,仍有工作要做,以显示基于酞菁颜料,特别是铜酞菁的油墨的兴趣。然而,与稳定性、分散性和退火温度有关的问题往往限制了这四种类型填料的应用。在这篇综述中,我们介绍了用于导电油墨配方的可用导电填料的一般信息,重点是金属颗粒、碳填料、颜料和聚合物。讨论了经常使用的印刷技术的影响和技术要求,以及为获得目标性能而进行的后处理。此外,还描述了便携式电子设备中使用的各种类型的可扩展和柔性基板的表面特性。此外,还展出了一些类型的印刷柔性电子元件以及电子纺织品在各个领域的显著应用。接下来,本文讨论了印刷柔性电子产品制造面临的主要挑战以及未来研究的建议
