In this study, we present a new method to fabricate superhydrophobic laser-induced graphene (SH-LIG) surfaces by immobilizing the polyimide (PI) film on the copper sheet, which enables uniform laser processing (single pass laser etching) over a wider range of microsecond laser parameters (10.5\u201319.5 W). Subsequently, the SH-LIG was obtained by vacuum-assisted immersion in stearic acid, resulting in a water contact angle greater than 150\u00b0, roll angle stabilized at 6\u00b0, and hydrophobic stability at a high temperature of 90 \u00b0C. Analysis by Raman spectroscopy (Raman), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) showed that the LIG fabricated at optimal power (19.5 W) had a more developed C sp2 network (I2D\/IG \u2248 0.5) and pore structure, which significantly improved the photothermal conversion efficiency (up to 252 \u00b0C in air and 180 \u00b0C on water). On this basis, a simple micro-driver based on SH-LIG was designed. Experiments showed that the maximum velocity of the SH-LIG boat can reach an adjustable propulsion velocity of 45.6 mm\/s (related to the laser processing power and the intensity of the driving light), which is 132% higher than that of the LIG boat. This work provides insights into the preparation of high-quality LIG and their application in photothermally driven micro actuators, highlighting the synergies between structural optimization, surface engineering, and photothermal performance.<\/jats:p>","DOI":"10.3390\/ma18081880","type":"journal-article","created":{"date-parts":[[2025,4,21]],"date-time":"2025-04-21T20:38:26Z","timestamp":1745267906000},"page":"1880","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Fabrication of Superhydrophobic Surfaces from Laser-Induced Graphene and Their Photothermally Driven Properties"],"prefix":"10.3390","volume":"18","author":[{"given":"Yue","family":"Zhao","sequence":"first","affiliation":[{"name":"State Key Laboratory of High-Performance Precision Manufacturing, Dalian University of Technology, Dalian 116024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yonghui","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of High-Performance Precision Manufacturing, Dalian University of Technology, Dalian 116024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of High-Performance Precision Manufacturing, Dalian University of Technology, Dalian 116024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haodong","family":"Fu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of High-Performance Precision Manufacturing, Dalian University of Technology, Dalian 116024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of High-Performance Precision Manufacturing, Dalian University of Technology, Dalian 116024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3769-2069","authenticated-orcid":false,"given":"Jinlong","family":"Song","sequence":"additional","affiliation":[{"name":"State Key Laboratory of High-Performance Precision Manufacturing, Dalian University of Technology, Dalian 116024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8323-7289","authenticated-orcid":false,"given":"Xin","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of High-Performance Precision Manufacturing, Dalian University of Technology, Dalian 116024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"26","DOI":"10.1038\/s41528-022-00161-z","article-title":"A Soft and Stretchable Electronics Using Laser-Induced Graphene On Polyimide\/PDMS Composite Substrate","volume":"6","author":"Wang","year":"2022","journal-title":"NPJ Flex.
