摘要

本研究提出了一种简单而经济的策略来提高高填充（HF）聚合物复合材料的加工流动性和力学性能，同时保持其阻燃性。合成了离子液体（IL），特别是1-烷基-3-甲基咪唑磷酸（[AMIM]PA），并将其掺入HF氢氧化镁(MH)/线性低密度聚乙烯（LLDPE）（60/40重量比）复合材料中。含有5 wt%的1-十六烷基-3-甲基咪唑磷酸盐（[HDMIM]PA）的MH/LLDPE复合材料在加工特性上有了显著改善，平衡扭矩值降低了50.7%，熔体流动指数提高了13倍，冲击强度提高了133%。形态学和流变学分析表明，[HDMIM]PA有效地促进了MH颗粒与LLDPE基体之间的界面润滑和相容性，从而提高了整体性能。阻燃性评估表明，[AMIM]PA作为膨胀阻燃剂，使材料更安全。因此，本研究提供了对IL在提高HF聚合物复合材料性能中的作用的全面理解，为开发先进的复合材料提供了一个有希望的策略。

Green multifunctional ionic liquid for enhancing processing flowability, toughness, and flame retardancy of highly filled MH/LLDPE composites

This study proposes a facile and cost-effective strategy to improve the processing flowability and mechanical properties of highly filled (HF) polymer composites while retaining their flame retardancy. Ionic liquids (IL), specifically 1-alkyl-3-methylimidazolium phosphate ([AMIM]PA), were synthesized and incorporated into HF magnesium hydroxide (MH)/linear low-density polyethylene (LLDPE) (60/40 by weight) composites. The MH/LLDPE composite containing 5 wt% of 1-hexadecyl-3-methylimidazole phosphate ([HDMIM]PA) exhibited significant improvements in processing characteristics, demonstrating a 50.7% reduction in equilibrium torque values, a maximum 13 times enhancement in melt flow index, and a 133% increase in impact strength. Morphological and rheological analyses demonstrated that [HDMIM]PA effectively promoted interfacial lubrication and compatibility between MH particles and LLDPE matrix, and consequently enhanced the overall properties. The flame retardancy assessments revealed that [AMIM]PA functioned as an intumescent flame retardant to make the material safer. This study thus provides a comprehensive understanding of the role of IL in enhancing the performance of HF polymer composites, offering a promising strategy for the development of advanced composites.
