主　　题：FeSiAl polyurethane acrylic inorganic/organic interface microwave absorption anti-corrosion 

摘      要：Microwave absorption materials are prone to degradation in extremely humid and salty environments,and it is still challenging to develop a dense and firm interface to protect microwave ***,a robust FeSiAl@PUA@SiO2(PUA:acrylic polyurethane)gradient hybrid was prepared through plasma-enhanced chemical vapor deposition(PECVD)to achieve efficient microwave absorption and anti-corrosion *** organic/inorganic dual coat of PUA/SiO2 not only facilitated the interface polarization but also effectively reduced the dielectric constant and optimized impedance *** to the unique hybrid structure,the(PECVD-FeSiAl@PUA)@SiO_(2) exhibited highly efficient microwave absorbing performance in frequency bands covering almost the entire Ku-bands(12-18 GHz)with a minimum reflection loss(RLmin)of−47 dB with a matching thickness of 2.3 *** organic/inorganic dual protection effectively shields against the corrosive medium,as the corrosion potential and the polarization resistance increased from−0.167 to−0.047 V and 8,064 to 16,273Ω·cm^(2),*** the corrosion current decreased from 3.04×10^(−6) to 2.16×10^(−6) A/cm^(2).Hence,the plasma-enhanced densification of PUA created a strong bridge to integrate FeSiAl and organic/inorganic components acquiring dual-function of efficient microwave absorption and anticorrosion,which opened a promising platform for potential practical absorbers.
