Basalt fiber (BF), because of having high strength-to-cost ratio, could be suitable for industrial applications replacing the carbon and glass fibers. However, the lack of surface functionality restricts its potential interfacial interactions with the reinforced matrix. Various surface modification approaches are used to tailor the surface properties of BFs such as coating nanomaterials and attaching chemical moieties. In this study, a successful deposition of graphene on basalt fabric was done using eco-friendly and simple electrophoretic deposition method. The confirmation of attached graphene oxide and graphene was done through the scanning electron microscope, Raman spectroscopy, and X-ray photoelectroscopy. Later, the effect of graphene coating on the thermal properties of BF was studied through thermogravimetric analysis and differential scanning calorimetry. Results show that the graphene was successfully coated on BF, and in the presence of graphene coating, the crystallization of BF delayed from 697 to 716°C because of the formation of a protective layer of graphene. Graphene-coated BF could be used further in fiber-reinforced composites to improve the interfacial interaction between the matrix and fiber.

石墨烯在玄武岩纤维上的电泳沉积，用于复合材料

玄武岩纤维（BF）由于具有高的强度/成本比，因此可能适合替代碳纤维和玻璃纤维的工业应用。然而，缺乏表面功能性限制了其与增强基质的潜在界面相互作用。各种表面改性方法可用于调整高炉的表面性能，例如涂覆纳米材料和附着化学部分。在这项研究中，使用环保且简单的电泳沉积方法成功地将石墨烯沉积在玄武岩织物上。通过扫描电子显微镜，拉曼光谱和X射线光电子显微镜确认附着的氧化石墨烯和石墨烯。之后，通过热重分析和差示扫描量热法研究了石墨烯涂层对高炉热性能的影响。结果表明，石墨烯被成功地涂覆在BF上，并且在存在石墨烯涂层的情况下，由于形成了石墨烯保护层，BF的结晶从697℃延迟到716°C。石墨烯包覆的高炉可以进一步用于纤维增强的复合材料中，以改善基体与纤维之间的界面相互作用。
