一步合成和微图案化不同类型的碳纳米材料，如无定形碳或三维石墨烯，其具有通用的电化学，热学和机械性能，对于微电子，传感器和可穿戴设备的制造是有利的。在这里，我们报告了一个直接的激光写入方法，同时合成和图形石墨碳从液体有机前体。我们已经测试了各种各样的液体有机前体，并确定了成功的激光诱导溶剂热沉积是有益的化学特性。激光沉积的碳具有准晶-多晶结构，并且具有10- 3到10-4Ω m量级的电阻率，该电阻率可通过激光功率的变化来调节。激光沉积碳的这些特性，加上直接写入具有微米级分辨率的定制图案的能力，使这些碳材料成为用于能量存储和传感等应用的令人兴奋的候选材料。
One-step synthesis and micropatterning of different types of carbon nanomaterials, such as amorphous carbon or three-dimensional graphene which have versatile electrochemical, thermal, and mechanical properties, are advantageous for the fabrication of microelectronics, sensors, and wearable devices. Here, we report a direct laser writing method to simultaneously synthesize and pattern graphitic carbon from liquid organic precursors. We have tested a wide range of liquid organic precursors and identified the chemical characteristics that are beneficial for successful laser-induced solvothermal deposition. The laser-deposited carbon exhibits a paracrystalline-to-polycrystalline structure and has electrical resistivities on the order of 10–3to 10–4Ω m which is tunable through variations in the laser power. Such properties of the laser-deposited carbon, coupled with the ability to direct-write custom patterns with microscale resolution, make these carbon materials exciting candidates for use in applications such as energy storage and sensing.
