利用卷曲纳米技术,制备了Ti/Cr、Cr/SiO、SiO/SiO_2、SiO/Cr 4种不同金属、氧化物组合的双层纳米薄膜微管,研究了不同组合和参数对微管结构的影响,结果表明纳米薄膜沉积温度、沉积速率和纳米薄膜的厚度以及材料本身的物理性质等因素对微管的半径大小影响显著。利用Ti/Pt双层纳米薄膜微管结构制备的催化微马达在H_2O_2溶液中依靠气泡推动,表现出超快的速度和强大的推动力,在靶向给药、人工智能机器人、生物传感等领域具有应用潜力。另外,通过斜掠角蒸渡和纳米卷曲技术结合,制备了另外一种三维结构-不同螺旋角的Ti金属弹簧。
The double-walled nanofilms of Ti / Cr, Cr / SiO, SiO / SiO 2 and SiO / Cr were prepared by curling nanotechnology. The effects of different combinations and parameters on the structure of microtubules were studied The results show that the deposition temperature, the deposition rate and the thickness of the nanofilm and the physical properties of the material itself have significant effects on the radius of the microtubule. The catalytic micro-motor prepared by Ti / Pt double-walled nano-film microtubule structure relies on bubbles promoted in H 2 O 2 solution, showing ultra-fast speed and powerful driving force. In the target administration, artificial intelligence robots, biosensing and the like The field has potential applications. In addition, another three-dimensional structure of Ti metal springs with different helix angles was prepared by the combination of sweep and nanofloc technique.
