In this study, mulch films based on wheat straw fiber and an environmentally friendly modifier were prepared via in situ polymerization and tested as the ridge mulch for crops. The mechanical properties of the straw fiber film were significantly enhanced by the modification. In particular, the films exhibited a noticeable increase in dry and wet tensile strength from 2.35 to 4.15 and 0.41 to 1.51 kN\/m, respectively, with increasing filler content from 0% to 25%. The contact angle of the straw also showed an improvement based on its hydrophilicity. The crystallinity of the modified film was higher than that of the unmodified film and increased with modifier content. The changes in chemical interaction of the straw fiber film were determined by Fourier transform infrared spectroscopy, and the thermal stability of the unmodified film was improved by in situ polymerization. Scanning electron microscopy images indicated that the modifier was uniformly dispersed in the fiber film, resulting in an improvement in its mechanical properties. The modified straw fiber films could be degraded after mulching for approximately 50 days. Overall, the superior properties of the modified straw fiber film lend it great potential for agricultural application.<\/jats:p>","DOI":"10.3390\/ma15155170","type":"journal-article","created":{"date-parts":[[2022,7,27]],"date-time":"2022-07-27T04:59:16Z","timestamp":1658897956000},"page":"5170","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Fabrication and Characterization of Degradable Crop-Straw-Fiber Composite Film Using In Situ Polymerization with Melamine\u2013Urea\u2013Formaldehyde Prepolymer for Agricultural Film Mulching"],"prefix":"10.3390","volume":"15","author":[{"given":"Qian","family":"Lang","sequence":"first","affiliation":[{"name":"Faculty of Engineering, Northeast Agricultural University, Haerbin 150030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chuanhao","family":"Liu","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Northeast Agricultural University, Haerbin 150030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoxin","family":"Zhu","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Northeast Agricultural University, Haerbin 150030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Northeast Agricultural University, Haerbin 150030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0494-5453","authenticated-orcid":false,"given":"Shengming","family":"Zhang","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Northeast Agricultural University, Haerbin 150030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3072-2499","authenticated-orcid":false,"given":"Longhai","family":"Li","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Northeast Agricultural University, Haerbin 150030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuang","family":"Liu","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Northeast Agricultural University, Haerbin 150030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haitao","family":"Chen","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Northeast Agricultural University, Haerbin 150030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"109126","DOI":"10.1016\/j.polymdegradstab.2020.109126","article-title":"Environmental degradation and efficacy of a sprayable, biodegradable polymeric mulch","volume":"175","author":"Borrowman","year":"2020","journal-title":"Polym.
