项目摘要

In 2022, we concluded our investigation of the graphitization mechanism and changes in the composition of transparent polymers during laser irradiation using a promising computer simulation called ReaxFF. This simulation provided valuable insights into how transparent polymers are converted into laser-induced graphene (LIG) and enabled the analysis of chemical structure changes within the polymer, contrasting with experimental data. Additionally, the generation of gases during laser irradiation was taken into account.We also examined the applicability of LIG fabricated within transparent polymer composites as pressure sensors and energy harvesting devices. The LIG produced directly inside the transparent polymer exhibited superior performance as pressure sensors and energy harvesting devices compared to conventional LIG. This enhanced performance can be attributed to the increased air gaps and larger surface area of the internal LIG compared to traditional LIG production methods.In summary, our research in 2022 successfully utilized ReaxFF simulations to gain insights into the graphitization mechanism of transparent polymers during laser irradiation, as well as the potential applications of LIG produced within transparent polymer composites as pressure sensors and energy harvesting devices. The findings of this study showcase the advantages of internal LIG in terms of performance and demonstrate the potential of this method to revolutionize the field of LIG production and applications.

在2022年，我们使用有前途的计算机模拟（称为reaxff）对透明聚合物的石墨化机制和透明聚合物组成的变化进行了结论。该模拟提供了有关如何将透明聚合物转化为激光诱导的石墨烯（LIG）的宝贵见解，并使聚合物内化学结构变化的分析与实验数据相反。此外，考虑了激光照射期间的气体的产生。我们还研究了在透明聚合物复合材料中制造的LIG的适用性，作为压力传感器和能量收集设备。与传统的LIG相比，直接在透明聚合物内部产生的LIG作为压力传感器和能量收集设备表现出卓越的性能。与传统的LIG生产方法相比，这种增强的性能可以归因于内部LIG的增加和更大的表面积。总而言之，我们在2022年的研究成功利用了Reaxff模拟，以洞悉激光辐射过程中透明聚合物的石墨化机制，以及在临时Polodest Polufts Composs Composs Composs Composs Composs Composs ins Promymerss ins Promysers ins Polufts的应用。这项研究的发现在性能方面展示了内部lig的优势，并证明了这种方法可以彻底改变LIG生产和应用领域的潜力。
