摘要

激光诱导碳化技术可以方便地生成石墨碳,被认为是制造任意导电微结构的一种有前途的技术。众所周知,激光辐照条件对所产生产品的形态和结晶度有很大影响。然而,与炉子的讨论不同的是,对应用温度和生成物的详细考虑很常见,而对激光诱导碳化过程的讨论却很有限。近年来,有报告显示,使用聚二甲基硅氧烷(PDMS)作为前驱体材料不仅能产生石墨碳,还能形成碳化硅。在本研究中,我们利用热成像摄像机测量激光诱导碳化过程中的温度变化,旨在阐明 PDMS 温度波动与所生成石墨碳的形态和结晶度之间的相关性。结果表明,通过激光诱导碳化形成的石墨碳的形态和结晶度并不完全取决于激光照射区域的最高温度。激光照射过程中的温度变化对这些材料的选择性生成起着至关重要的作用。

Temperature measurement and morphological/crystalline differences in the laser-induced carbonization of polydimethylsiloxane
Laser-induced carbonization, which allows for the facile generation of graphitic carbon, is considered a promising technique for fabricating arbitrary conductive microstructures. The morphology and crystallinity of the resulting product are acknowledged to be significantly influenced by laser irradiation conditions. However, unlike discussions pertaining to furnaces where detailed considerations of applied temperature and resulting products are common, discussions on the process of laser-induced carbonization are limited. In recent years, reports have shown that using polydimethylsiloxane (PDMS) as a precursor material not only produces graphitic carbon but also results in the formation of silicon carbide. In this study, we utilized a thermographic camera to measure temperature changes during laser-induced carbonization, aiming to elucidate the correlation between PDMS temperature fluctuations and the morphology and crystallinity of the resulting graphitic carbon. The results demonstrate that the morphology and crystallinity of the graphitic carbon formed through laser-induced carbonization are not solely determined by the maximum temperature in the laser-irradiated area. The temperature changes during laser irradiation play a crucial role in the selective generation of these materials.

期刊介绍: The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optical Materials Express (OMEx), OSA''s open-access, rapid-review journal, primarily emphasizes advances in both conventional and novel optical materials, their properties, theory and modeling, synthesis and fabrication approaches for optics and photonics; how such materials contribute to novel optical behavior; and how they enable new or improved optical devices. The journal covers a full range of topics, including, but not limited to: Artificially engineered optical structures Biomaterials Optical detector materials Optical storage media Materials for integrated optics Nonlinear optical materials Laser materials Metamaterials Nanomaterials Organics and polymers Soft materials IR materials Materials for fiber optics Hybrid technologies Materials for quantum photonics Optical Materials Express considers original research articles, feature issue contributions, invited reviews, and comments on published articles. The Journal also publishes occasional short, timely opinion articles from experts and thought-leaders in the field on current or emerging topic areas that are generating significant interest.
