Abstract
A friction preventing apparatus and a method of manufacturing the same are provided. The apparatus includes: a first object; a second object spaced apart from the first object and facing the first object; and a plurality of charged nanoparticles provided on a surface of one of the first and second objects, such that the nanoparticles are disposed between the first object and the second object. A potential difference is formed between the first and second objects. The nanoparticles may be positively charged and may adhere to the first object, and the first object has a potential lower than a potential of the second object. The nanoparticles may be negatively charged and may adhere to the second object, and the second object has a potential higher than a potential of the first object.
