Embodiment 1

[0015] The electrolyte composition is 0.2mol L -1 Phosphate buffer solution with a pH of 6.86, containing 0.4% polyacrylic acid in the buffer solution, 0.10mol L -1 Lithium perchlorate and 0.15mol L -1 pyrrole. Then, take 0.00V as the start potential, 0.85V as the end potential, and scan for 20 cycles at a scanning speed of 25mv / s; or electrolytically polymerize at a constant potential of 0.85V for 100 seconds.

Embodiment 2

[0017] The electrolyte composition is 0.2mol L -1 EDTA buffer solution with a pH of 9.00, in the buffer solution, 0.10mol·L -1 Lithium perchlorate and 0.15mol L -1 pyrrole. Then, take 0.00V as the start potential, 0.85V as the end potential, and scan for 20 cycles at a scanning speed of 25mv / s; or electrolytically polymerize at a constant potential of 0.85V for 100 seconds.

Abstract

The method for directly forming polypyrrole nano wire on the surface of electrode includes the following steps: making pyrrole, polyanion dopant or high-valence anion dopant and supporting electrolyte into electrolyte, adopting composite electrode and utilizing constant potential method or circulation volt-ampere method to make the above-mentioned electrolyte undergo the process of electrolytic polymerization, and utilizing the control of pyrrole concentration, dopant concentration and supporting electrolyte solution concentration to attain the goal of directly forming polypyrrole nano wire with different length and diameter on the surface of the electrode. The diameter of nano wire can be 50 nano.

Description

technical field [0001] The invention relates to a method for directly generating polypyrrole nanowires on an electrode surface. The invention belongs to the preparation technology of conductive polymer nanofibers. Background technique [0002] Conductive polymers were discovered in the late 1970s, and its discovery changed the view that polymers are all insulators. Polypyrrole is one of the most researched conductive polymers, which has good room temperature stability and high conductivity. And it has the advantages of easy synthesis and easy control of conditions. Its applied research has covered energy storage (as electrode materials for batteries and supercapacitors), electrocatalysis, organic electrochemistry, bioelectrochemistry, photoelectrochemistry, electroanalytical chemistry, sensors, actuators, electrochromic displays, electronics Components, electromagnetic shielding, military concealment and anti-corrosion and many other fields. The α...
