Surface Wettability of PA2200 3D Printing Parts by Laser Irradiation

The hydrophilic surfaces of PA2200three-dimensional(3D)printing parts are prepared quickly through248 nm KrF excimer laser irradiation,whose contact angles decrease from 121°to 70°and phase structures do not change after irradiation.With the calibration tools of X-ray diffractometer,Raman spectroscopy,scanning electron microscope,X-ray photoelectron spectroscopy and so on,the surface morphologies and microstructures of printing parts,number and types of polar functional groups are analyzed.The Cassie-Baxter model is also studied.The experimental results show that KrF excimer laser irradiation can not only make PA2200 3Dprinting part surfaces smooth,but also simultaneously generate C O double hydrophilic groups,and thus the surface wettability of PA2200 3Dprinting parts are improved and controlled.
