A pH-responsive carbon foam (CF) made from liquefied larch sawdust (LLS) with switchable wettability was fabricated in this work. After grafted with poly 4-vinyl pyridine (P4vp), the CF obtained a switchable wettability surface, which allowed the CF to exhibit superhydrophilicity and superhydrophobicity at different pH levels, respectively. The results revealed that the pH-responsive CF possessed a three-dimensional (3D) spongy-like skeleton and porous structure with a diameter between 50 and 200 \u00b5m. Thus, the pH-responsive CF could absorb 15\u201335 g\/g of oil\/organics in a neutral aqueous solution at pH = 7 and desorb all the absorbate within 40 s after immersion in an aqueous solution at pH = 1. Moreover, only about 2.8% loss was observed for organic (chloroform) absorption and recovery after reusing up to 15 cycles, which indicated promising prospects in oil and organic recovery.<\/jats:p>","DOI":"10.3390\/polym15030638","type":"journal-article","created":{"date-parts":[[2023,1,27]],"date-time":"2023-01-27T02:30:38Z","timestamp":1674786638000},"page":"638","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["pH-Responsive Carbon Foams with Switchable Wettability Made from Larch Sawdust for Oil Recovery"],"prefix":"10.3390","volume":"15","author":[{"given":"Jia","family":"Tan","sequence":"first","affiliation":[{"name":"College of Materials Science and Engineering, Northeast Forestry University, Harbin 150040, China"},{"name":"Key Laboratory of Bio-Based Material Science and Technology of the Ministry of Education, Northeast Forestry University, Harbin 150040, China"},{"name":"Engineering Research Center of Advanced Wooden Materials of the Ministry of Education, Northeast Forestry University, Harbin 150040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiaming","family":"Sun","sequence":"additional","affiliation":[{"name":"College of Materials Science and Engineering, Northeast Forestry University, Harbin 150040, China"},{"name":"Key Laboratory of Bio-Based Material Science and Technology of the Ministry of Education, Northeast Forestry University, Harbin 150040, China"},{"name":"Engineering Research Center of Advanced Wooden Materials of the Ministry of Education, Northeast Forestry University, Harbin 150040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunhui","family":"Ma","sequence":"additional","affiliation":[{"name":"College of Materials Science and Engineering, Northeast Forestry University, Harbin 150040, China"},{"name":"Key Laboratory of Bio-Based Material Science and Technology of the Ministry of Education, Northeast Forestry University, Harbin 150040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sha","family":"Luo","sequence":"additional","affiliation":[{"name":"Key Laboratory of Bio-Based Material Science and Technology of the Ministry of Education, Northeast Forestry University, Harbin 150040, China"},{"name":"Engineering Research Center of Advanced Wooden Materials of the Ministry of Education, Northeast Forestry University, Harbin 150040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Bio-Based Material Science and Technology of the Ministry of Education, Northeast Forestry University, Harbin 150040, China"},{"name":"Engineering Research Center of Advanced Wooden Materials of the Ministry of Education, Northeast Forestry University, Harbin 150040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shouxin","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Materials Science and Engineering, Northeast Forestry University, Harbin 150040, China"},{"name":"Engineering Research Center of Advanced Wooden Materials of the Ministry of Education, Northeast Forestry University, Harbin 150040, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"301","DOI":"10.1038\/nature06599","article-title":"Science and technology for water purification in the coming decades","volume":"452","author":"Shannon","year":"2008","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1756","DOI":"10.1007\/s12274-017-1484-8","article-title":"In situ fastening graphene sheets into a polyurethane sponge for the highly efficient continuous cleanup of oil spills","volume":"10","author":"Kong","year":"2017","journal-title":"Nano Res."},{"key":"ref_3","doi-asserted-by":"crossref","unstructured":"Hailan, S.M., Ponnamma, D., and Krupa, I.
