1. the preparation method of an overlength thin titanium tube inner surface Nano tube array of titanium dioxide, it is characterised in that comprise the following steps:

  • A) titanium pipe (1), conductive wire (2), sealing-plug (3) pass sequentially through detergent, deionized water, ethanol, deionized water and clean in ultrasound wave, then dry up with nitrogen after repeatedly rinsing with deionized water;

    B) conductive wire after drying up is fixed on the shaft core position of sealing-plug, is passed through titanium pipe, and sealing-plug is fixed on titanium pipe one end, with fixture tensioning conductive wire, keeps the alignment of conductive wire and titanium pipe, and vertically fixes;

    C) inject containing ammonium fluoride and the ethylene glycol solution of water in titanium pipe;

    D) connecting DC power anode outside titanium pipe, conductive wire connects power cathode, carries out anodic oxidation after switching on power;

    E) pull down the titanium pipe (1) after anodic oxidation, and carry out ultrasonic cleaning titanium pipe (1) with deionized water.
