Harnessing Laser-induced graphene (LIG) on various substrates, its optimization and application for various electronic devices has increased in the recent years. LIG has been reported as an alternative process for the realization of graphene for flexible electronics with excellent strength, conductivity and mechanical robustness. However, in a single-step manufacturing process, the development of a cost-effective, scalable electronic system using LIG is very challenging. In this work, a novel, simple, low-cost, and solid-state approach has been introduced to print and develop LIG-based conductivity traces and patterns. Here, the LIG conductive zones have been formed on various platforms by using phenolic resin (PR). The LIG regions were effectively developed from direct CO 2 laser ablation on the PR and polyvinyl alcohol (PR-PVA) composite sheets. This technique makes it possible to easily create highly conductive arrays on various substrates for realizing the componen...

酚醛树脂和酒精复合片材上的激光诱导石墨烯，用于柔性电子应用

近年来，利用激光诱导的石墨烯（LIG）在各种基板上进行了优化和优化，并将其应用于各种电子设备。据报道，LIG是实现柔性电子产品中石墨烯的一种替代方法，该石墨烯具有出色的强度，导电性和机械强度。但是，在单步制造过程中，使用LIG开发具有成本效益的可扩展电子系统非常具有挑战性。在这项工作中，已经引入了一种新颖，简单，低成本和固态的方法来打印和开发基于LIG的电导率迹线和图案。在此，LIG导电区已经通过使用酚醛树脂（PR）在各种平台上形成。LIG区域是通过在PR和聚乙烯醇（PR-PVA）复合板上直接进行CO 2激光烧蚀而有效开发的。
