preparation example Construction
[0026] A preparation method based on laser-induced super-hydrophilic PET surface, the method comprises the following steps:
[0027] Step 1, PET is attached to the glass surface
[0028] Prepare the attachment substrate 1 by spin-coating the absolute ethanol solution 2 on the glass surface, so that the PET film 3 is attached to the substrate surface 1 more smoothly;
[0029] Step 2, colored layer preparation
[0030] Depositing a colored seed layer 4 with a thickness of 0.03-3 μm on the surface of the sample by sputtering;
[0031] Step 3, laser-induced processing
[0032] Use a laser marking machine to scan the surface of the PET film to obtain a rough surface 5, that is, a hydrophilic layer, with a pulse repetition frequency of 10-100 kHz, a pulse width of 0.1-0.2, and a laser spot speed of 50-500 mm / s;
[0033] Step 4, alkaline solution corrosion
[0034] Use the solution method to etch the processed surface, adjust the alkaline solution to pH = 8-14, and the corrosion ...
