In this work, a smart superhydrophobic membrane (SHP) was obtained by dipping an off-the-shelf laboratory filter paper in an ethanol suspension of trichloro (1H,1H,2H,2H-tridecafluoro-n-octyl) silane, tetraethyl orthosilicate, and titanium dioxide nanoparticles with different dimensions of 20 and 100 nm. The selection of membrane substrates was optimized including different quantitative and quantitative filter papers with different filtration velocity (slow, intermediate, and fast). The as-prepared SHP was demonstrated to be superhydrophobic and photosensitive, which was used in the separation of carbon tetrachloride and water from their mixture and emulsion. Moreover, orderly aligned micropores were formed for the modified superhydrophobic filter papers by using nanosecond laser. Unidirectional penetration was obtained for the UV-irradiated paper with a bored pore in the range of 50\u2013500 \u03bcm in the systems of air\/water and water\/oil. This study may promote the understanding of unidirectional transportation of liquid droplet and facilitate the design of interfacial materials with Janus-type wettability.<\/jats:p>","DOI":"10.3390\/membranes12121188","type":"journal-article","created":{"date-parts":[[2022,11,28]],"date-time":"2022-11-28T01:58:46Z","timestamp":1669600726000},"page":"1188","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Smart Superhydrophobic Filter Paper for Water\/Oil Separation and Unidirectional Transportation of Liquid Droplet"],"prefix":"10.3390","volume":"12","author":[{"given":"Yu-Ping","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Chemistry and Materials Engineering, Hunan University of Arts and Science, Changde 415000, China"},{"name":"College of Chemistry and Chemical Engineering, Henan Institute of Science and Technology, Xinxiang 453000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ning","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering, Henan Institute of Science and Technology, Xinxiang 453000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"De-Liang","family":"Chen","sequence":"additional","affiliation":[{"name":"Changde Zhengyang Biotechnology Co., Ltd., Changde 415000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuan","family":"Chen","sequence":"additional","affiliation":[{"name":"Changde Zhengyang Biotechnology Co., Ltd., Changde 415000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meng-Jun","family":"Chen","sequence":"additional","affiliation":[{"name":"Changde Zhengyang Biotechnology Co., Ltd., Changde 415000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin-Xin","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering, Henan Institute of Science and Technology, Xinxiang 453000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Liu, H., Gao, S.W., Cai, J.S., He, C.L., Mao, J.J., Zhu, T.X., Chen, Z., Huang, J.Y., Meng, K., and Zhang, K.Q.
