Major content of this work includes five aspects as follows:(1). Oxygen sensitive materials had been prepared by carrier covalence method, and the preparation mechanism of the materials had been investigated by FI-IR, SEM, and the detection experiment of oxygen. Then through the detection of oxygen, the sensitivity and stability had been estimated, and it was studied that the properties of materials would be affected by the various factors.(2). Oxygen sensitive materials had been prepared by carrier covalence-cross linking method, and the preparation mechanism of the materials had been investigated by FI-IR, SEM, and the detection experiment of oxygen. Then through the detection of oxygen and spectrophotometer, the sensitivity and stability had been estimated, and it was studied that the properties of materials would be affected by the various factors.(3). For the detection of gaseous oxygen, the fiber optical sensor on basis of oxygen sensitive materials had a respond time of 10s, detection limit of 5ppmand detection precision of 0.5%. The sensor had good repeatability and stability, a less delay and at least 1 year life-span.
