Surface modification of carbon fiber cloth by femtosecond laser direct writing technology

In this work, carbon fiber cloth is proposed by femtosecond laser direct writing technology (FLDWT) with different conditions. As consequence, series of laser-induced periodic surface structures (LIPSS) are constructed on the surface of carbon fiber cloth, and the hydrophobic property of carbon fiber cloth is changed dramatically, the contact angle of pristine carbon fiber cloth sharply decreases from 150.8° to 20.4°, which makes carbon fiber cloth successfully support platinum nanoparticles in a hydrophilic reaction environment.
