一种二氧化钛纳米颗粒辅助红外纳秒激光在玻璃表面制备微结构的方法

The present invention relates to a method for preparing microstructures on glass surface with titanium dioxide nanoparticles assisted by infrared nanosecond laser, which includes the following steps: (1) dropping titanium dioxide nanoparticle hydrogel onto the surface of a glass sample; (2) placing another sheet The glass is pressed on the surface of the hydrogel so that the hydrogel is evenly distributed between the two pieces of glass, and then left to stand horizontally for a period of time to allow the titanium dioxide nanoparticle hydrogel to dry; (3) Separate the glass sheets to obtain uniform titanium dioxide nanometers Particle-coated glass; (4) Use an infrared nanosecond laser with a wavelength of 1064nm for microstructure processing; (5) After processing, the samples obtained in step 3 are ultrasonically cleaned with acetone, absolute ethanol, and deionized water for 10 minutes. To remove the titanium dioxide nanoparticles adhered on the surface, a glass sample with microstructure is obtained; it solves the problem that the quartz glass has a very low absorption rate for the 1064nm infrared nanosecond laser and cannot achieve material removal.
