Abstract Laser-induced graphene (LIG) has provided a facile and effective strategy for graphene formation via one-step laser scribing on polymer structures. However, the direct utilization of LIG toward multifunctionalization for high-performance fiber-reinforced polymeric composites (FRPs) is rarely explored. Aiming to integrate the laser-induced graphitic structure (LIGS) with FRPs through the most facilitated approach, herein, we innovatively report a self-converted strategy for manufacturing multifunctional LIGS-hybridized FRP-composites (LIGC). By incorporating the laser irradiation process on either pristine or fully-cured epoxy prepregs at different stages of composite manufacturing, two paths of LIGS formation have been naturally developed to respectively implant the designable graphitized patterns interlaminarly or superficially. Benefiting from systematic processing-dependent-structural analysis, diversified properties of LIGC can be modulated for simultaneously achieving the optimized electrical conductivity (~0.74 kΩ/sq) as well as the negligible mechanical degradation (

具有激光诱导石墨结构的多功能复合材料的自转换策略

摘要 激光诱导石墨烯 (LIG) 为通过在聚合物结构上一步激光划线形成石墨烯提供了一种简便有效的策略。然而，很少探索直接利用 LIG 实现高性能纤维增强聚合物复合材料 (FRP) 的多功能化。为了通过最方便的方法将激光诱导石墨结构（LIGS）与 FRP 相结合，我们创新地报告了一种用于制造多功能 LIGS 杂化 FRP 复合材料（LIGC）的自转换策略。通过在复合材料制造的不同阶段对原始或完全固化的环氧树脂预浸料进行激光照射工艺，自然地开发了两条 LIGS 形成路径，分别在层间或表面植入可设计的石墨化图案。
