The porous film could be obtained from the solution of 0.8 wt%, whose pore diameters ranged from 50 nm to 500 nm. The hydrophobic porous surface with a water contact angle (CA) of 144.7\u00b0 could be transferred into a hydrophilic surface with CA of 25\u00b0 by applying a voltage. The water adhesive force on the porous film increased with the increase of the external voltage. The electro-controllable wettability and adhesion of the porous film have potential application in manipulating liquid collection and transportation.<\/jats:p>","DOI":"10.3390\/ma8041817","type":"journal-article","created":{"date-parts":[[2015,4,16]],"date-time":"2015-04-16T10:37:57Z","timestamp":1429180677000},"page":"1817-1830","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Conductive Polymer Porous Film with Tunable Wettability  and Adhesion"],"prefix":"10.3390","volume":"8","author":[{"given":"Yuqi","family":"Teng","sequence":"first","affiliation":[{"name":"School of Chemical & Environmental Engineering, China University of Mining & Technology, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuqi","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering, Yan'an University, Yan'an, Shaanxi 716000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liping","family":"Heng","sequence":"additional","affiliation":[{"name":"School of Chemistry and Environment, Beihang University, Beijing 100191, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiangfu","family":"Meng","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Capital Normal University, Beijing 100048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiaowen","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Chemical & Environmental Engineering, China University of Mining & Technology, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Environment, Beihang University, Beijing 100191, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,4,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"16217","DOI":"10.1021\/am504386q","article-title":"Honeycomb-like periodic porous LaFeO3 thin film chemiresistors with enhanced gas-sensing performances","volume":"6","author":"Dai","year":"2014","journal-title":"ACS Appl.
