Interface and Quality of Nanometer TiO₂ Coated Optical Fiber

【Abstract】 The interface and quality of TiO₂ coated optical fiber,which is obtained by dipping nude fibers into TiO₂ slurry,were investigated. The coating processes were carried out under different designed conditions,including various adhesives,solid content of TiO₂ slurry,times of cladding and followed heat-treat temperature. The interface and coating qualities were observed by scanning electron microscope. Coating defects,such as cracking,breaking off and the inhomogeneity of the cladding corresponds to different coating condition were analyzed. As a result, a well-combined and durable TiO₂ coating in optical fiber surface was obtained under definite optimizing experimental conditions and parameters.更多还原
