Nickel-plated ultrahigh molecular weight polyethylene (UHMWPE) samples were prepared by an electroless coating method followed by hot pressing. The concentration of Ni in the composites was varied between 3.98 and 10.88 in volume percentage. XRD results revealed that Ni coating was successfully realized on the surface of UHWMPE particles confirmed by SEM–EDS. Ni thickness on the UHMWPE particles has thickness of 2 μm and there was also self-precipitated Ni plates as well as additive Ni particles according to SEM. Hardness values of Ni-coated UHMWPE–Ni composites increased 30% with increasing Ni content. The EMI-SE of the composite increased from 49 up to 70 dB by increasing Ni content for both X and Ku-band with respect to Ni concentration. Our samples, performed very high shielding within X band and also Ku band compared to most of other reports in the open literature, can be suitable for high-performance requirements especially in aerospace applications.

镀镍的超高分子量聚乙烯（UHMWPE）样品是通过化学镀方法，然后进行热压制备的。复合材料中Ni的浓度以体积百分比在3.98至10.88之间变化。XRD结果表明，通过SEM-EDS证实，在UHWMPE颗粒表面成功实现了镍涂层。UHMWPE颗粒上的Ni厚度为2μm，并且根据SEM还存在自沉淀的Ni板以及添加的Ni颗粒。随着Ni含量的增加，镀Ni的UHMWPE-Ni复合材料的硬度值增加了30％。通过增加X和Ku波段相对于Ni浓度的Ni含量，复合材料的EMI-SE从49 dB提高到70 dB。我们的样品
