Application of Nanotechnology in Reduction of Drag Force and Optimization of Sea Floats Performance by Using from ZnO2

One of the most important methods of decrease the frictional drag, the newest and more applicable method, is use nanotechnology in this field. The very large researches has been performed in the theoretical and practical area about nano-meterial with special specifications, circumstance of production, manner of its application, recognize mechanism of application, effective factors, also the way of optimum use, specially in sea applications and aerospace. Today this research field that is effective in decrease fuel, increase movable speed and cleanliness of environment, has been expanding. Among applications and fields that nanotechnology cause wonderful change in decrease fractional drag especially in sea industries, can be pointed to different nano-covers with different application, using nano-material in the covers of anti-moss, in decrease fraction of body of floats and submarines, in increase resistance to stroke, scratch, crack and also more durability of used color and their resistance against acidic space and totally in sea environment and many other an important applications that can say that has been happened huge change in this industry. In this essay, different researches and considered theories in case of ZnO2 s application is classified, added up, collected and presented.
