In this study, carbon fiber cloth is modified using femtosecond laser direct writing technology. As a result, a series of laser-induced periodic surface structures are formed on the surface of the carbon fiber cloth, leading to a significant change in its hydrophobic property. This modification enables the carbon fiber cloth to successfully support platinum nanoparticles in a hydrophilic reaction environment.
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 degrees to 20.4 degrees, which makes carbon fiber cloth successfully support platinum nanoparticles in a hydrophilic reaction environment.
