Microscopic morphology and composition analysis verified the successful synthesis of the modified UHMWPE fibers. By precisely adjusting the concentration of the reaction solution and optimizing reaction conditions, hydroxylated UHMWPE exhibited significantly enhanced surface hydrophilicity (water contact angle reducing from 128° to 67°), without compromising its mechanical properties (tensile strength remained above 90%). Durability testing confirmed that the surface hydroxylation of UHMWPE and the grafting of a silane coupling agent (SCA) onto APP synergistically enhanced interfacial bonding. Besides, the binding energy and interfacial shear properties of modified fibers, which were calculated through molecular dynamics simulations, indicated that the hydrogen bond significantly enhanced the interaction between UHMWPE and APP.

Bio-based modifiers rarely deliver flexibility, char formation, and effective flame inhibition at low levels, leaving a gap in achieving multifunctional PLA systems. Here, phosphorus-modified castor oil (PMCO) was synthesized via solvent-free transesterification of castor oil with trimethyl phosphate, yielding a bio-based additive tailored for dual mechanical and flame-retardant enhancement. PMCO, used alone or in combination with ammonium polyphosphate (APP), was incorporated into PLA via melt blending to evaluate synergistic effects. The phosphorus moieties in PMCO promoted char formation and gas-phase radical quenching, while castor oil's long-chain fatty acids imparted flexibility; APP reinforced condensed-phase char development. Low PMCO loadings (1–3 wt%) enhanced tensile strength (up to 59.33 MPa) via plasticizing–reinforcing effects, whereas 5 wt% reduced stiffness; APP counteracted this in hybrid PLA/2.5%PMCO/2.5%APP, which restored tensile strength (58.15 MPa), doubled elongation at break (6.89%), and improved deformation resistance. Fire tests showed LOI rising from 19% (PLA) to 30% (hybrid), with UL-94 reaching V-0 and complete suppression of melt-dripping.

This dual-modification strategy achieves balanced toughness and strong flame retardancy in bio-based PLA at low additive levels.

The microcapsules featured uniform particle size and smooth, dense surfaces morphologies. Furthermore, the release behavior and fire extinguishing efficiency of the microcapsules were systematically analyzed. Key findings are summarized as follows: The pyrolysis of the microcapsules proceeds through four distinct stages: moisture evaporation, core material volatilization, shell rupture, and wall decomposition. The release temperature and rupture temperature of the microcapsules were determined to be 95.5°C (with a cumulative release rate of 15.49%) and 108.5°C (with a cumulative release rate of 98.62%), respectively. Release kinetics fitting demonstrated that the zero-order model best described the release behavior at 95.5°C (<i>R</i><sup>2</sup> = 0.9884), indicating a constant-rate diffusion mechanism. At 108.5°C, the release process conformed to the Higuchi model (<i>R</i><sup>2</sup> = 0.9176), confirming a diffusion-dominated mechanism. In confined-space fire extinguishing tests, the deployment of the microcapsules reduced combustion time to 36 s, constrained the peak temperature to 143.3°C, and rapidly lowered oxygen concentration to 6.9% within the 35–38 s timeframe. Notably, significant transformation of flame morphology was observed after 10 s of combustion, accompanied by the rapid formation of a yellowish moderate-temperature zone.
