Abstract

The invention discloses a preparation method of a friction-reduction anti-adhesion nano organic film based on a micro device, comprising the following steps of: with aluminum, copper, magnesium and alloys thereof used in a micro / nano electromechanical system as substrate materials, matching different substrate materials selected from different water-soluble triazine organic compound salts with alkaline-support electrolysis salts; and preparing the nano organic film with hydrophobic function, friction reduction and adhesion resistance by adopting a three-electrode mode constant-current, cyclic-voltammetry and constant-potential organic film plating technology. A static contact angle of the prepared nano organic film and distilled water can reach above 110 degrees, a friction coefficient can be reduced below 0.05, the maximum adhesive force can be reduced to 103mN, the friction coefficient and the adhesive force can be effectively reduced, and the film thickness is controllable. The invention has the advantages of simple process, short period and low cost and easy industrialized production and can be widely used for the friction reduction and adhesion resistance of the micro device in the micro / nano electromechanical system and improve tribological characteristics.
