Preparation And Properties Of Indium Tin Oxide Fibrous Membrane Composite Optical Fiber

Quartz optical fiber was coated by the conductive and transparent tin-doped indium oxidefibrous membrane can obtain the properties of conductive/transparent/light, which can be used inthe related fields of sensor. In this paper, ITO fibrous membrane composite optical fiber wasprepared by electrospinning and calcination processes. The morphology and structure of obtainedsamples were characterized by Field Emission Scanning Electron Microscope(FE-SEM),Transmission electron microscopy(TEM), X-ray diffraction(XRD); Digital multimeter,UV–visible spectrophotometero and Luminance colorimeter were employed to study the opticaland electrical properties. The effects of processing conditions on the structure and properties ofthe samples have been investigated. Then the optimum sample was obtained.In the experiment, it was hard to prepare the ITO films on the quartz optical fiber surface.This paper optical fiber silanization can successfully fabricate ITO fibrous membrane coating onthe optical fiber through a homemade collector, Then studied the effects of different rotationspeed on the morphology of ITO fibrous membrane. The results indicated that when the rotationspeed was1000r/min, the ITO fibrous membrane showed the best quality.ITO fibrous membrane was successfully prepared by a method of electrospinning, followedby annealing in the air, the effects of annealing in the temperature ranges of400-800℃on themorphology, structure, resistivity, transmittance in visible region of ITO fibrous membrane andquartz optical fiber light performance have been studied. The results showed that when theannealing temperature was800℃, ITO fibrous membrane composite optical fiber has the beststructure and performance.Film thickness got by controlling the spinning time will affect the structure and propertiesof electrospinning film composite fiber. Changes in the morphology, structure, resistivity,transmittance in visible region of ITO fibrous membrane and quartz optical fiber lightperformance were discussed with the increase of film thickness. It was found that film thicknesscan improve the resistivity of ITO fibrous membrane, the film transmittance and the endluminous intensity of fibre decreases. We got that two hours was the best spinning time, the film has the good conductivity with the visible light transmittance greater than85%, and the quartzoptical fiber has the good light performance.This paper made a depth discussion on the preparation and properties of ITO fibrousmembrane composite optical fiber, and provided the experimental and theoretical foundation forthe preparation and properties of ITO fibrous membrane composite optical fiber in the future.
