Abstract Quasi-one-dimensional (Q1D)nickel nanostructures were prepared by a facial wet chemical process, and then the nickel chains/polyvinylidene fluoride (PVDF) composites were fabricated using the hot-molding procedure. Both the complex permittivity and permeability of the Ni/PVDF composites could be artificially adjusted by changing the nickel proportions, which contribute to enhancing the microwave absorption. An excellent reflection loss (RL) of −42.08 dB at 7.4 GHz with a low filler loading(20 wt%)and effective bandwidth (RL

准一维纳米结构超小镍的微波吸收增强与双非线性磁共振

摘要 采用面湿化学法制备了准一维（Q1D）镍纳米结构，然后采用热成型工艺制备了镍链/聚偏二氟乙烯（PVDF）复合材料。Ni/PVDF复合材料的复介电常数和磁导率都可以通过改变镍的比例来人为调节，这有助于增强微波吸收。在 7.4 GHz 下具有 -42.08 dB 的出色反射损耗 (RL)，填充物含量低 (20 wt%) 和有效带宽 (RL
