However, commonly used modification methods often compromise the fiber mechanical properties or surface reactivity due to structural damage. In this paper, a water-soluble system consisting of phytic acid imidazole salt and biobased benzoxazine was devised to modify a regenerated cellulose fabric through water-phase immersion. Benefiting from the neutral solution and self-assembly coating, the modified fabric (F-RCF) exhibited a typical self-extinguishing behavior while maintaining good structural integrity and mechanical properties. By further combining F-RCF with a DOPO-containing epoxy resin blend (FEB) to prepare a fiber-reinforced green composite (F-RCF/FEB), the results indicated that the co-curing reaction between the modifier and resin matrix contributed to improved interfacial adhesion. This enabled the simultaneous enhancement of tensile modulus (from 9.82 to 11.29 MPa), impact strength (from 6.58 to 7.26 kJ m<sup>−2</sup>) and interlaminar shear strength (from 11.41 to 13.89 MPa). More importantly, F-RCF/FEB exhibited excellent anti-flammability in terms of a high limiting oxygen index value of 34.3% and a UL-94 V-0 rating, and the peak heat release and total heat release were also markedly reduced by 44.9% and 36.9%, respectively. Mechanism analysis revealed that the modified system effectively prevented the wick effect and provided an inhibitory effect in the gaseous phase, as well as a barrier effect in the condensed phase. This study presents a non-destructive modification strategy for plant fibers, which may also inspire the synchronous enhancement of interfacial compatibility and fire-proof performance of PFRCs. © 2025 Society of Chemical Industry.</p>","PeriodicalId":20404,"journal":{"name":"Polymer International","volume":"74 6","pages":"528-537"},"PeriodicalIF":3.6,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PHAs exhibit properties that are analogous to those of synthetic plastics. The production of PHAs offers a multitude of advantages, primarily due to their biodegradability and biocompatibility. The most naturally occurring form of PHAs are the polyhydroxybutyrates (P(3HB)s). The major limitations of P(3HB)s are their brittle nature and inferior mechanical properties. Hence, these biopolymers have been observed to have limited biotechnological applications. In contrast to P(3HB)s, copolymers of PHAs have almost all the desirable properties, making them suitable for high-end applications such as those in the medical sector. Structural modifications in PHA molecules have expanded the scope of their applications, including in medical implants, wound healing and bone grafts. It is noteworthy that considerable progress has been made in the field of PHA nanocomposites, which are now being explored for their biotechnological applications in drug delivery, tissue engineering and biosensors.

Raman spectroscopy and X-ray photoelectron spectroscopy were used to analyze the char layer after the CONE test, and the thermogravimetric–infrared test was used to analyze the gas products at the maximum rate of thermal decomposition.
