Description
Summary:With the rapid development of information technology, electromagnetic shielding materials are playing an increasingly significant role in electronic reliability, healthcare, and national defense security. Hence, developing high performance electromagnetic shielding materials with thin thickness, low density, wide bandwidth, and strong absorption has attracted great interests. Recently, polyvinylidene fluoride (PVDF) as high-performance electromagnetic shielding materials has grabbed considerable attention, owing to its low density, good flexibility, stable corrosion resistance and favorable shaping capability. In this review, we firstly introduce the theory of electromagnetic shielding. In the main part, the preparation and recent advances of PVDF-based electromagnetic shielding composites are summarized, including single-, binary-, and multi-component filler composites, microstructure design of composites, and the factors influencing the EMI SE performance. The key point to enhance the EMI SE performance is to modulate the electromagnetic and dielectric properties of the composites to create diversified loss mechanisms. Finally, the shortcomings, challenges, and prospects of PVDF-based electromagnetic shielding materials are also put forward, which will be helpful to people working in the related fields.
