Abstract

The present invention uses long-chain mercaptan and aniline which are easily adsorbed on gold surface as raw material, and adopts the following steps: firstly, making silicon wafer sample undergo the process of surface treatment, using photo-etching technique to form regular pattern on the silicon surface, using said template as mold, pouring Sylgard 184 on its patterned surface, solidifying and forming at proper temperature to form elastic stamp with relief structure; then utilizing vacuum thermal deposition process to obtain a gold layer with a certain thickness on the silicon wafer or general microslide, and utilizing microcontact printing method to form a patterned octodecamercaptan self-assembled film on the gold surface; finally, using electrochemical polymerization method to prepare patterned polyaniline film.

Description

technical field [0001] The invention relates to a method for preparing a patterned conductive polyaniline film on a gold surface. Background technique [0002] In recent years, the research on the patterning method of conductive polymers has attracted more and more attention. Patterned conductive polymers have many uses, such as making actuators, biosensors, and can replace metals in nano / micro-manufacturing to prepare integrated circuits (Science 2000, 290:1532. Adv. Mater. 2002, 14:1837). Traditionally, the patterning of conductive polymers can be done by photolithography, electron beam etching, etc. However, these methods not only require expensive equipment, but also may cause damage to the polymer layer. Therefore, microcontact printing technology has become very important as a non-lithographic patterning technology. Fabrication of patterned self-assembled monolayers by microcontact printing. It serves as a template for regioselective deposition and has a guiding eff...
