摘要
二氧化锡(SnO2)具有稳定的理化性质、较高的可见光透过率和电导率,在隐身材料领域具有良好的应用前景,然而单一元素掺杂改性SnO2基材料的红外与激光的兼容隐身性能有待进一步提升.为此,本研究采用静电纺丝技术结合热处理工艺分别制备了 Sn1-x-ySmxSbyO2(x=0,y=0;x=0.08,y=0.08;x=0.16,y=0;x=0,y=0.16)微纳米纤维,研究发现经600 ℃煅烧后,各产物均为单一金红石型结构,微观形貌均呈现相互交错的纤维状,纤维直径分布在300～400 nm之间.当x=0.08,y=0.08时,产物在3～5 μm和8～14μm的红外发射率均最低,为0.573和0.691,同时在1.06和1.54 μm激光工作波长处具有最低反射率,为0.19和0.16.同时,本研究重点阐述了双元素掺杂及纤维形貌对其性能的作用机制,为研究一种单一型、轻质化的红外与激光兼容隐身材料提供一定的实验依据.
Abstract
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.
