Abstract

Sequential dual-curing epoxy composites, such as the thiol-epoxy system, can potentially open new capabilities for end-products in the composite industry. This system remains stable after the initial curing and can undergo further reactions when exposed to a second stimulus, such as the use of magnetic induction: a remote and energy-efficient alternative. This study reports the first dual-curing thiol-epoxy resin reinforced with magnetic nanoparticles Fe3O4. The addition of Fe3O4 nanoparticles endows the polymer matrix with dual-stimuli shape memory, triggered by both conventional heating and the use of a magnetic field, broadening potential applications. The study examined various manufacturing conditions and loadings of Fe3O4, which improved the mechanical properties of the composites. The dual-response shape memory was evaluated by heating the polymer with both a conventional heat source and magnetic fields, resulting in a ~ 100% shape fixation and recovery ratio for either stimulus source, with superior performance under the magnetic field. Furthermore, under moderate magnetic fields, the system was able to reach temperatures as high as 160 °C, and the influence of various parameters on the efficiency of magnetic induction heating was studied by statistical analysis of design of experiments. Additionally, two proofs of concept were presented. In the first, the second curing step was performed under the in situ heating generated by the magnetic field, successfully fixing the temporary shape into the permanent form of the sample. In the second concept, the system was utilized as a smart switch or a threshold temperature sensor.

Graphical Abstract

用于远程/原位应用的顺序双固化硫醇环氧体系与Fe3O4纳米颗粒的纳米复合材料:热机械,形状记忆和感应加热性能
顺序双固化环氧复合材料,如硫醇-环氧体系,可以为复合材料行业的最终产品开辟新的能力。该系统在初始固化后保持稳定,并且在暴露于第二次刺激时可以进行进一步的反应,例如使用磁感应:一种远程且节能的替代方案。本研究首次报道了磁性纳米Fe3O4增强双固化硫醇-环氧树脂。Fe3O4纳米颗粒的加入使聚合物基体具有双刺激形状记忆,可以通过传统加热和磁场触发,从而扩大了潜在的应用范围。研究了不同的制造条件和Fe3O4的负载,提高了复合材料的力学性能。采用传统热源和磁场对聚合物进行加热,结果表明,两种热源对聚合物的形状固定和恢复率均为100%,在磁场下具有优异的形状记忆性能。在中等磁场条件下,系统温度可达160℃,并通过实验设计的统计分析,研究了各参数对磁感应加热效率的影响。此外,还提出了两个概念证明。在第一步中,在磁场产生的原位加热下进行第二步固化,成功地将临时形状固定为样品的永久形状。在第二个概念中,系统被用作智能开关或阈值温度传感器。图形抽象

期刊介绍: Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
