要約(英語): Functional textures with physical functions such as hydrophobicity are expected as a solution to improve the value of products. The purpose of this research was to achieve a femtosecond-pulsed laser processing method that can create hydrophobic micro-texture directly on a resin (polyethylene terephthalate) surface. A feedback control algorithm was proposed to achieve texture for improving the hydrophobicity. Pitch, tooth width, groove width, and depth were used as the geometric parameters of the micro-texture. Apparent contact angle of 144.9° was achieved with groove/tooth ratio of 9 when polyethylene terephthalate was processed with the hydrophobic micro-texture. We have achieved a processing speed that can process a 3 mm square area in 4 min. This laser processing technology will be realized as a low environmental impact, sustainable manufacturing that supports carbon neutrality and sustainability goals.
