摘要

摘要采用化学沉淀法制备了表面经磁铁矿(Fe3O4)修饰的碳纤维(CF)。通过采用超声波处理的三个后续涂层阶段进行处理。每个超声阶段后，涂层分别占改性纤维总重量的17%、33%和47%。拉曼光谱表明涂层中存在铁II和铁III态的混合物。以环氧树脂(ED-20)为基体，经PEPA固化，制备了复合材料。碳纤维填料的量分别为1、3、6 wt %。室温下，软磁样品的饱和磁化强度分别为0.37、0.83和1.72 emu/g。在这种情况下，碳纤维增强聚合物材料具有额外的功能，如磁性，有望在电力和能源行业的应用中发挥作用。

Soft magnetic composites of carbon fibers decorated with magnetite in an epoxy matrix

ABSTRACT The chemical precipitation was used to obtain carbon fibers (CF) with surface modified by magnetite particles (Fe3O4). Processing was carried out by employing up to three subsequent coating stages of ultrasonic treatments. After each sonication stage, the coating was 17, 33, and 47 wt. % of the total weight of the modified fibers. Raman spectroscopy indicates the presence in the coating of a mixture of iron II and III states. As-decorated fibers were used to fabricate composites with an epoxy resin (ED-20) matrix cured with PEPA. The quantity of the carbon fiber filler was of 1, 3, and 6 wt %. At room temperature, the saturation magnetization of the soft magnetic samples was 0.37, 0.83, and 1.72 emu/g for the indicated compositions. Carbon fiber reinforced polymer materials with extra functions such as magnetic in this case, are expected to be useful in applications from the power and energy industries.

期刊介绍： Providing a common forum for all soft matter scientists, Soft Materials covers theory, simulation, and experimental research in this rapidly expanding and interdisciplinary field. As soft materials are often at the heart of modern technologies, soft matter science has implications and applications in many areas ranging from biology to engineering. Unlike many journals which focus primarily on individual classes of materials or particular applications, Soft Materials draw on all physical, chemical, materials science, and biological aspects of soft matter. Featured topics include polymers, biomacromolecules, colloids, membranes, Langmuir-Blodgett films, liquid crystals, granular matter, soft interfaces, complex fluids, surfactants, gels, nanomaterials, self-organization, supramolecular science, molecular recognition, soft glasses, amphiphiles, foams, and active matter. Truly international in scope, Soft Materials contains original research, invited reviews, in-depth technical tutorials, and book reviews.
