氣泡驅(qū)動納米馬達制備及運動控制方法研究
[Abstract]:Nano motor is a kind of micro and nano scale machinery which can be used in many fields, especially in medical field, and has a large push-weight ratio and can realize the directional transportation of materials. Among them, self-driving nanometer-motor is widely concerned because it uses the matter energy in the environment, and converts the energy into the kinetic energy needed by its own motion to realize its own motion. At present, the research on self-driving nanometer-motor is focused on hydrogen peroxide system at home and abroad, through platinum catalytic decomposition of hydrogen peroxide to produce oxygen, realize self-drive of nano-motor. However, due to its dependence on the environmental system (hydrogen peroxide), it is not suitable for the wide use of human medicine. Through the analysis of body fluid composition, it can be seen that digestive fluid mainly in acid environment occupies the important proportion of body fluid. Therefore, based on the theory of nanometer motor motion, a new type of conical tubular nano motor model is designed and fabricated by analyzing the motion principle of nano motor, and the influence factors and control methods of its motion are studied. The theoretical model of conical double-layer tubular nano-motor is established to analyze the motion mechanism of bubble driven nano-motor and the important factors that affect the movement speed of nano-motor are emphatically analyzed. Considering the corrosion characteristics of acid solution, hydrogen ion characteristics of acid solution, chemical reaction rate, preparation method and safety, the composition of nano-motor was designed. The preparation process of nano-motor shell was established by template electrodeposition method. The main factors affecting the thickness of nano-motor shell were analyzed by microscopic imaging method. The relationship between the thickness of nano-motor shell and the electric quantity of deposition was obtained. At the same time, the effects of different electrodeposition methods on the morphology of inner pore solute were compared, and the separation process of nanometer motor was improved. The factors influencing the movement speed of nano motor are analyzed. By using the experimental method, the variation of the speed of the nanometer motor was studied under different pH value, different kinds of acid conditions and different reaction time. At the same time, the effect of solution viscosity on the motion state of nano motor was studied by experimental method. The non-contact magnetic control was adopted to change the original nickel metal adhesion process and the metal sputtering process was replaced by the template electrodeposition process to realize the motion control of the nano-motor. Based on the principle of primary battery and the preparation method of nano motor, the new nano motor of primary battery is optimized and compared with the original nano motor under the same conditions to verify the effect of increasing speed.
