In contrast to the conventional methods of improving interface and performances of UHMWPE fiber composites through fibre surface modification, this paper has reported a novel approach to deposit graphene oxide (GO) to increase the fiber/matrix interfacial shear strength (IFSS) of ultra high molecular weight polyethylene fibers (UHMWPE fiber) reinforced high density polyethylene (HDPE) composites. To validate our argument, GO has been synthesized and deposited over UHMWPE fiber through electrophoretic deposition. Tuned voltage lead to different thickness of deposited GO steadily increasing with the electric field up to 10 V/cm. Coated fibers have been aligned in a mold and an HDPE matrix has been used to create a single-fiber microcomposite. This latter has resulted to be muchhigher than the ILSS thus proving the efficiency of the new GO coating method here proposed for producing advanced graphene based composites. The failure of the composite at the GO/matrix rather than at the GO/UHMWPE fiber interface has been also confirmed by scanning electron microscopy observation of the fracture surfaces of microcomposites.

通过在UHMWPE纤维上电泳沉积氧化石墨烯来增强UHMWPE纤维/ HDPE复合材料的界面粘合力

与通过纤维表面改性来改善UHMWPE纤维复合材料的界面和性能的常规方法相反，本文报道了一种沉积氧化石墨烯（GO）的方法，以提高超高分子量纤维/基体的界面剪切强度（IFSS）。重量的聚乙烯纤维（UHMWPE纤维）增强的高密度聚乙烯（HDPE）复合材料。为证实我们的观点，GO已通过电泳沉积合成并沉积在UHMWPE纤维上。调谐电压导致沉积的GO的不同厚度随着电场的增加而稳定增加，直至10 V / cm。涂层纤维已在模具中对齐，并且HDPE基质已用于创建单纤维微复合材料。后者比ILSS高得多，从而证明了这里提出的用于生产高级石墨烯基复合材料的新型GO涂覆方法的效率。复合材料在GO /基体而不是GO / UHMWPE纤维界面处的破坏也已通过扫描电子显微镜观察到的微复合材料的断裂表面得到了证实。
