Abstract

Since its discovery, laser-induced graphene (LIG) has attracted much interest because this technique, having all the advantages of a laser processing technology, is more convenient and cost-effective than other graphene production methods. This work offers a detailed analysis of LIG structures produced by UV and CO laser irradiation from polyimide performed with surface scanning Raman spectroscopy combined with microscopy techniques. Although UV LIG has a less ordered structure than that obtained by CO laser irradiation, our study indicates that UV LIG can be patterned with a resolution higher than that obtained with CO laser irradiation and a much smaller penetration depth into the substrate.

摘要

自激光诱导石墨烯（LIG）被发现以来，它就引起了广泛关注，因为该技术具备激光加工技术的所有优点，比其他石墨烯制备方法更便捷且成本效益更高。这项工作结合显微镜技术，利用表面扫描拉曼光谱对通过紫外和CO激光辐照聚酰亚胺产生的LIG结构进行了详细分析。尽管紫外LIG的结构有序性不如CO激光辐照所获得的结构，但我们的研究表明，紫外LIG能够以高于CO激光辐照的分辨率进行图案化，并且对基底的穿透深度要小得多。
