摘要

采用溶胶-凝胶法制备了一种含Mn-Co铁氧体纳米粒子的柔性微波材料，用于2-6 GHz频率范围内的石油杂质检测。利用x射线衍射（XRD）和场发射扫描电镜（FESEM）对晶体进行了结构分析，发现晶体尺寸为21.67 ~ 22.53 nm，晶格常数为9.6873 ~ 9.7423 Å。振动样品磁强计（VSM）分析表明，Mn-Co铁氧体纳米复合材料表现出稳健的铁磁行为，随着锰含量的增加，其饱和磁化强度在58.50 ~ 24.51 emu/g之间，显示出磁性能的可调性。随着Mn含量的增加，聚乙烯醇（PVA）基材料的介电常数（εr）为6.63，损耗正切（Tδ）从0.0224增加到0.3254。双矩形嵌套谐振器（DRNR）的谐振频率分别为3.008 GHz、3.948 GHz、4.72 GHz、5.356 GHz和5.604 GHz，衰减范围为- 46.50 dB和- 21.07 dB。该传感器可有效识别油位，区分橄榄油（εr = 3.03）和棕榈油（εr = 3.18），为油杂质检测和先进的微波应用提供紧凑、高灵敏度的解决方案。

Development and analysis of flexible Mn–Co ferrite material incorporating dual-Rectangular nested resonator (DRNR) for enhanced oil impurity sensing

A flexible microwave material incorporating Mn–Co ferrite nanoparticles, synthesized via the sol-gel method, was developed for oil impurity detection within the 2–6 GHz frequency range. Structural analysis using X-ray diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM) revealed crystallite sizes of 21.67–22.53 nm and lattice constants ranging from 9.6873 to 9.7423 Å, dependent on composition. Vibrating Sample Magnetometer (VSM) analysis revealed that the Mn–Co ferrite nanocomposites exhibit robust ferromagnetic behavior, with saturation magnetization ranging from 58.50 emu/g to 24.51 emu/g as manganese content increases, highlighting the tunability of their magnetic properties. The polyvinyl alcohol (PVA)-based material exhibited a dielectric constant (ε_r) of 6.63 and an increasing loss tangent (T_δ) from 0.0224 to 0.3254 with higher Mn content. The Dual-Rectangular Nested Resonator (DRNR) design demonstrated resonance at 3.008 GHz, 3.948 GHz, 4.72 GHz, 5.356 GHz, and 5.604 GHz, with attenuation levels between −46.50 dB and −21.07 dB. The sensor effectively identified oil levels, distinguishing olive oil (ε_r = 3.03) and palm oil (ε_r = 3.18), offering a compact, high-sensitivity solution for oil impurity detection and advanced microwave applications.
