To address this challenge, this study employed a reactive melt-grafting method to prepare maleic anhydride (MA)-grafted poly(butylene adipate-co-terephthalate) (PBAT\u2013MA), providing an effective approach to improve the interfacial compatibility between PLA and PBAT, thereby significantly enhancing the toughness and impact resistance of PLA and expanding its application scope. The grafting reaction process of PBAT\u2013MA was investigated, as well as its toughening mechanism and effect on PLA. The results showed that at a maleic anhydride concentration of 2 wt%, the obtained PLA\u2013PBAT\u2013MA composite material exhibited the best performance, with a fracture elongation of 358.1%, 450.4% higher than that of the unmodified composite material. The impact strength was 333.9 kJ\/m2, 917.3% higher than that of the unmodified composite material. This enhanced effect is attributed to the optimal MA concentration preserving the tough structure of PBAT while effectively bridging the interface between PLA and PBAT, promoting efficient stress transfer between the two phases, and ultimately achieving exceptional toughness.<\/jats:p>","DOI":"10.3390\/polym17162264","type":"journal-article","created":{"date-parts":[[2025,8,21]],"date-time":"2025-08-21T14:46:04Z","timestamp":1755787564000},"page":"2264","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Structure, Mechanical Properties, and Rheological Characteristics of Poly(Butylene Adipate-co-Terephthalate)\u2013Polylactic Acid Blends Modified via In Situ Maleic Anhydride Grafting"],"prefix":"10.3390","volume":"17","author":[{"given":"Min","family":"Jin","sequence":"first","affiliation":[{"name":"Fujian Dazhuang Bamboo Industry Technology Co., Ltd., Jian\u2019ou 353100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bei","family":"Qi","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Woody Oil Resources Utilization, Northeast Forestry University, Harbin 150040, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kang","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Woody Oil Resources Utilization, Northeast Forestry University, Harbin 150040, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijun","family":"Cao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Woody Oil Resources Utilization, Northeast Forestry University, Harbin 150040, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pengrui","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Woody Oil Resources Utilization, Northeast Forestry University, Harbin 150040, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ce","family":"Sun","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Woody Oil Resources Utilization, Northeast Forestry University, Harbin 150040, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8306-993X","authenticated-orcid":false,"given":"Jianfeng","family":"Zhan","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Woody Oil Resources Utilization, Northeast Forestry University, Harbin 150040, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhuofeng","family":"Shao","sequence":"additional","affiliation":[{"name":"College of Home and Art Design, Northeast Forestry University, Harbin 150040, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haiyan","family":"Tan","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Woody Oil Resources Utilization, Northeast Forestry University, Harbin 150040, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2301-5630","authenticated-orcid":false,"given":"Yanhua","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Woody Oil Resources Utilization, Northeast Forestry University, Harbin 150040, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"118829","DOI":"10.1016\/j.indcrop.2024.118829","article-title":"Preparation and properties of bamboo fiber\/polylactic acid composite modified with polycarbodiimide","volume":"218","author":"Yang","year":"2024","journal-title":"Ind.
