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。 Titanium dioxide nanotube arrays were prepared on the surface of pure titanium and silver-doped titanium dioxide nanotube arrays were successfully prepared by thermal-driven silver-doping technology with both biological activity and antibacterial properties. The results show that the mechanism by which titanium oxide nanotube arrays thermally drive silver doping is the low temperature decomposition of silver nitrate in a confined reaction space and the synergism with titanium oxide at low temperature. The titanium oxide nanotube arrays are saturated with silver nitrate and annealed at 300 ° C., so that not only the low temperature transformation of the titania nanotube arrays from amorphous to rutile but also the low temperature decomposition of the silver nitrate can be realized simultaneously.
