通过直接激光写入的银纳米颗粒光还原合成是一种能够在非常特定的聚合物上产生铜微轨道的方法。然而，一些重要的3D打印聚合物，如丙烯腈丁二烯苯乙烯（ABS）和丙烯酸酯，在其表面上不接受这种处理。这项工作提出了一种方法，以生产铜微电路的3D基板上，这些材料通过使用直接激光写入在低功率（32 mW CW二极管激光器）。我们表明，通过在3D打印的几何形状上涂覆一层薄薄的聚酰亚胺（PI），然后进行一系列化学处理和低功率激光诱导光还原，可以使用银作为催化剂生产铜轨道。通过FTIR和X射线光电子能谱法监测该过程的不同阶段的层的表面化学。通过无电镀铜沉积在激光图案化区域上选择性地生长铜轨道，其电导率为（1.2 ± 0.7）× 107 S m−1，宽度小至28 μm。这些图案可以写在3D结构上，甚至可以写在腔体内。该技术通过集成不同的电路来演示，包括3D打印的光聚合物丙烯酸酯上的LED电路和ABS 3D弯曲几何形状上的钙钛矿太阳能电池。低功率激光图案化方法可以在一些重要的3D打印聚合物的3D表面上产生铜微裂纹，例如ABS和丙烯酸酯光聚合物。用一个简单的32 mW的CV激光二极管产生了小至28 μm的径迹。
Silver nanoparticle photoreduction synthesis by direct laser writing is a process that enables copper micro-track production on very specific polymers. However, some important 3D printing polymers, such as acrylonitrile butadiene styrene (ABS) and acrylates, do not accept this treatment on their surface. This work presents an approach to produce copper microcircuitry on 3D substrates from these materials by using direct laser writing at low power (32 mW CW diode laser). We show that by coating a thin layer of polyimide (PI) on a 3D-printed geometry, followed by a sequence of chemical treatments and low-power laser-induced photoreduction, copper tracks can be produced using silver as catalyst. The surface chemistry of the layer through the different stages of the process is monitored by FTIR and X-ray photoelectron spectroscopy. The copper tracks are selectively grown on the laser-patterned areas by electroless copper deposition, with conductivity (1.2 ± 0.7) × 107 S m−1 and a width as small as 28 μm. The patterns can be written on 3D structures and even inside cavities. The technique is demonstrated by integrating different circuits, including a LED circuit on 3D printed photopolymer acrylate and a perovskite solar cell on an ABS 3D curved geometry. A low-power laser patterning method enables the production of copper microcracks on 3D surfaces of some important 3D printing polymers, such as ABS and acrylate photopolymer. Tracks as small as 28 μm are produced with a simple 32 mW CV laser diode.
