摘要
随着电子信息和通信技术的发展,电磁波在我们的生活中无处不在,因此迫切需要开发高效的电磁屏蔽(EMI)材料来减少电磁波污染。医疗器械、5G 通信、航空航天等领域都需要坚韧耐用、柔韧轻薄、具有优异机械性能和高效电磁屏蔽性能的材料来满足实际需求。本研究将轻质、耐磨、稳定的高分子材料聚氨酯(Pur)与镍漆结合,在高压下利用张力压制机将聚氨酯涂覆在 3 k 碳纤维布表面,形成单面电磁屏蔽复合材料。实验验证表明,添加 50 wt%聚氨酯(Pur)和 50 wt%镍漆制成的复合材料样品 C5P5CP 在整个 X 波段(8-12 GHz)具有稳定高效的电磁屏蔽性能,平均电磁屏蔽值为 60 dB。在 1、3、5、7 和 9 N 的可变载荷摩擦下,它都能表现出优异的摩擦性能,并在电化学实验中表现出最佳的耐腐蚀性能。电磁波吸收是复合材料屏蔽电磁波的主要方式。这可以减少二次反射带来的危害。这种材料的制造工艺简单,具有优异的机械性能,包括轻质、柔韧和耐磨。其高效的电磁屏蔽性能为各领域屏蔽材料的设计提供了新思路,有望得到实际应用。
Polyurethane nickel lacquer coated carbon fiber cloth with excellent mechanical properties and high electromagnetic shielding performance
With the development of electronic information and communication technology, electromagnetic waves are everywhere in our lives, so there is an urgent need to develop efficient electromagnetic shielding (EMI) materials to reduce electromagnetic wave pollution. Medical devices, 5G communications, aerospace and other fields require materials that are tough and durable, flexible and thin, have excellent mechanical properties and high-efficiency electromagnetic shielding properties to meet practical needs. In this study, polyurethane (Pur), a lightweight, wear-resistant and stable polymer material, was combined with nickel paint and applied to the surface of 3 k carbon fiber cloth using a tension-pressing machine under high pressure to form a single-sided electromagnetic shielding composite material. Experimental verification shows that the composite sample C5P5CP made by adding 50 wt% polyurethane (Pur) and 50 wt% nickel paint has stable and efficient electromagnetic shielding performance in the entire X-band (8–12 GHz), with an average electromagnetic shielding value of 60 dB. It can exhibit excellent friction performance under variable load friction of 1, 3, 5, 7 and 9 N, and shows the best corrosion resistance in electrochemical experiments. Electromagnetic wave absorption is the main way composite materials shield against electromagnetic waves. This reduces the harm from secondary reflections. The material has a simple manufacturing process and excellent mechanical properties, including lightness, flexibility, and wear resistance. Its efficient electromagnetic shielding performance offers new ideas for designing shielding materials in various fields, and it is expected to have practical applications.
