在这项工作中，我们展示了使用商业CO2激光切割系统来蚀刻二氧化硅气凝胶整料的表面，而不会对整料造成整体结构损伤。文字、照片和其他图像可以很容易地在气凝胶表面复制。蚀刻气凝胶样品的视觉外观取决于样品和观察者相对于光源的取向，这使得这种方法对于美术、开窗和建筑中的应用在视觉上具有吸引力。[图形]。气凝胶可以使用商用激光切割机轻松蚀刻。气凝胶的激光蚀刻产生了吸引人的视觉效果。在表面蚀刻过程中保持了气凝胶整体的结构完整性。
In this work we demonstrate the use of a commercial CO2 laser cutting system to etch the surface of silica aerogel monoliths without causing overall structural damage to the monoliths. Text, photographs and other images can be readily reproduced on an aerogel surface. The visual appearance of the etched aerogel sample depends on the orientation of the sample and the viewer relative to the light source, which renders this approach visually attractive for applications in fine art, fenestration and architecture.[GRAPHICS].Aerogels can be readily etched using a commercial laser cutter.Attractive visual effects result from laser etching of aerogels.Structural integrity of the aerogel monolith is preserved during surface etching.
