摘　　要：二氧化锡(SnO_(2))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SnO^(2)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Sn_(1-x-y)Sm_(x)Sb_(y)O_(2)(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300~400nm之间。当x=0.08,y=0.08时,产物在3~5μm和8~14μm的红外发射率均最低,为0.573和0.691,同时在1.06和1.54μm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。Tin dioxide(SnO_(2))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 infrared and laser compatible stealth performance of single element doping modified tin dioxide-based materials is expected to be further improved.Therefore,in this study,Sn_(1-x-y)Sm_(x)Sb_(y)O_(2)(x=0,y=0;x=0.08,y=0.08;x=0.16,y=O;x=0,y=0.16)micro/nano fibers were prepared by electrostatic spinning technology combined with heat treatment process.The results show that after calcination at 600 C,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 3-5μm and 8-14μm,which is 0.573 and 0.691,and the lowest reflectivity at 1.06 and 1.54μm laser operating wavelength,which is 0.19 and 0.16.In addition,the mechanism 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.
