本研究結合磁性匿蹤材料、導電高分子及有機矽氧烷抗腐蝕材料,利用水熱法及溶膠-凝膠製程,合成有機矽氧烷/鐵氧磁體(Ormosil/Ferrite)及有機矽氧烷/鐵氧磁體@聚苯胺( Ormosil/Ferrite@Polyaniline)複合物作為抗腐蝕匿蹤塗料。實驗中改變鎳鋅鐵氧磁體和核殼型鎳鋅鐵氧磁體@聚苯胺含量及改變鎳鋅鐵氧磁體與聚苯胺比例,利用光譜分析(FTIR、13C- 29Si-CP/MAS NMR)、動力學研究(Spin-Lattice Relaxation Time)、電磁特性分析(EPR、SQUID)、紅外光波遮蔽試驗及耐腐蝕效能測試(Accelerated Salt Spray Corrosion Resistance Tests and Electrochemical Measurements),探討複合物的耐腐蝕效能、電磁特性及紅外光波段遮蔽效果,同時比較添加磁性材料及導電高分子後,對有機矽氧烷(Ormosil)抗腐蝕材料防腐蝕性能影響。
Hybrid coatings based on organically modified silicate (Ormosil)/ Ni0.5Zn0.5Fe2O4 and Ormosil/Ferrite@Polyaniline were synthesized through a sol–gel technique. These hybrid films were deposited via spin coating onto an aluminum alloy to improve the corrosion protection and as infrared stealth coatings. To understand the effect of the NiZn ferrite content on the chain dynamics of the Ormosils, we have measured TSiH and , respectively. The characterization of the hybrids was discussed on the basis of the structural characterization, including Fourier transform infrared (FTIR), X-ray diffraction (XRD), 29Si and 13C NMR. EPR and SQUID techniques have been used to investigate the ferromagnetic behavior and blocking temperature (Tb). The characteristic of thermal extinction of hybrid coatings was studied with IR thermal-imaging equipment in 3-5 and 8-12 μm. Additionally, electrochemical analysis and accelerated corrosion testing have been used to investigate the relation between relaxation behavior and corrosion resistance of the hybrids.
