Abstract
Nickel-coated silk composites (Ni/silk fiber) were prepared by electroless nickel-plating using a kind of natural silk as template in first stage.The silk templates were then removed to get Ni hollow fiber by annealing the Ni/silk fiber at 220 °C for 2 h in air or 700 °C for 1.5 h in nitrogen.The prepared Ni/silk fiber and Ni hollow fiber were characterized by X-ray diffraction (XRD),scanning electron microscope (SEM),field emission scanning electron microscope (FE-SEM) and differential thermal analysis and thermogravimetric analysis (TG-DTA).The values of complex permittivity,complex permeability,dielectric and magnetic loss of Ni/silk fiber and Ni hollow fiber were measured in the frequency range of 2–18 GHz by a reflection/transmission approach using a network analyzer.The results indicate that the dielectric loss of Ni/silk fiber and Ni hollow fiber is high up to 1 even at 18 GHz while the magnetic loss is low.

摘要
镀镍丝复合材料（镍/蚕丝纤维），制备了镀镍镀在第一阶段使用模板类的天然蚕丝。丝绸模板拆下来，然后在220退火得到的Ni /丝纤维°，2小时在空气或氮气中700 ? 1.5 ° C间?镍中空纤维。制备的Ni /镍丝纤维和中空纤维用X射线衍射（XRD），扫描电子显微镜（SEM）和场发射扫描电子显微镜（FE - SEM）和差热分析和热重分析（TG - DTA）表征。复介电常数，复磁导率，介电常数和磁镍/镍丝纤维和中空纤维损失的价值进行计量之2-18由反射/使用网络分析仪的传输方式GHz的频率范围。结果表明，镍/镍丝纤维和中空纤维介电损耗高，甚至高达1千兆赫，而在18磁损耗低。
