Preparation of Sn1-x-ySmxSbyO2 Micro/Nanofibers and Their Infrared and Laser Compatible Stealth Properties
Tin dioxide(SnO2)has stable physical and chemical properties,high visible light transmittance and electrical conductivity,and has good application prospects in the field of stealth materials.However,the infra-red and laser compatible stealth performance of single element doping modified tin dioxide-based materials is ex-pected to be further improved.Therefore,in this study,Sn1-x-ySmxSb O2(x=0,y=0;x=0.08,y=0.08;x=0.16,y=0;x=0,y=0.16)micro/nano fibers were prepared by electrostatic spinning technology combined with heat treat-ment process.The results show that after calcination at 600 ℃,the products all have a single rutile structure,with interlacing fibrous morphology and fiber diameter ranging from 300 to 400 nm.When x=0.08,y=0.08,the product has the lowest infrared emissivity at 3-5 µm and 8-14 µm,which is 0.573 and 0.691,and the lowest reflectivity at 1.06 and 1.54 µm laser operating wavelength,which is 0.19 and 0.16.In addition,the mecha-nism of dual element doping and fiber morphology on its properties is emphasized,which provides experimental basis for the research of a single,light infrared and laser compatible stealth material.
