The MWFs samples\u2019 microstructure properties were characterized using SEM, EDS, XPS, FTIR analyses, and water contact angle tests. The results revealed that all the MWF surfaces were wrapped by a distinct coating layer and had different elemental compositions and chemical groups, demonstrating the significant effect of the four modifications on the WF surfaces. The hydroxyl, amino, or nitrile groups were grafted onto the WF surfaces causing improvement of the hydrophilicity and reactivity. Furthermore, all the MWFs as the reinforced materials were incorporated into the industrial waste phosphogypsum (PG) to manufacture the phosphorous-building gypsum composites (PBGC). The effects on the micro-morphology and mechanical properties of the PBGC were evaluated. The results also show the improvement in flexural and compressive strength with the addition of MWFs into the PBGC, due to the enhancement of the compactness between the MWF and phosphogypsum matrix. In particular, the effects of three compound modifiers on the flexural and compressive strength are more significant. The highest flexural and compressive strength was contributed by the PBGC-MWF4 with 2% dosage using a compound modifier of dopamine hydrochloride and 3,4-dihydroxy benzonitrile, which were enhanced 61.04% and 25.97% compared with the PBG.<\/jats:p>","DOI":"10.3390\/molecules27248668","type":"journal-article","created":{"date-parts":[[2022,12,8]],"date-time":"2022-12-08T02:51:56Z","timestamp":1670467916000},"page":"8668","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Surface-Treated Recycling Fibers from Wind Turbine Blades as Reinforcement for Waste Phosphogypsum"],"prefix":"10.3390","volume":"27","author":[{"given":"Lilin","family":"Yang","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering, University of Jinan, Jinan 250000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weilin","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, University of Jinan, Jinan 250000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daobei","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, University of Jinan, Jinan 250000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, University of Jinan, Jinan 250000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongzhi","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, University of Jinan, Jinan 250000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Na","family":"Cui","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Architecture, University of Jinan, Jinan 250000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"105601","DOI":"10.1016\/j.resconrec.2021.105601","article-title":"An Integrated Geospatial Approach for Repurposing Wind Turbine Blades","volume":"170","author":"Delaney","year":"2021","journal-title":"Resour.
