    摘要:

    本文通过在纯钛表面制备得到氧化钛纳米管阵列后,再利用热驱动掺银技术,成功制备得到既具有生物活性,又具有抗菌性能的银掺杂氧化钛纳米管阵列。研究表明氧化钛纳米管阵列热驱动掺银的机理为硝酸银在受限反应空间中的低温分解及其与氧化钛低温相变的协同。将氧化钛纳米管阵列浸泡饱和硝酸银后,在300℃条件下热处理,不仅能实现氧化钛纳米管阵列由无定型转变为金红石型的低温相变,还能同时实现硝酸银的低温分解。

    Abstract:

    In this paper, the Ag-doped titania nanotube arrays was successfully fabricated by steps of preparation of titania nanotube arrays on the surface of pure titania and the Ag-doped technology of thermal drive, which has excellent bioactive and antibacterial performance. The researches show that the mechanism of thermal drive Ag-doped is the collaboration of thermal decomposition of silver nitrate in the limited space with the phase transition of titania at low temperature. After being soaked in saturated silver nitrate and annealed at 300℃, the titania nanotube arrays can realize not only the low temperature phase transition from amorphous to rutile, but also the low temperature decomposition of silver nitrate within it.
