Abstract

The invention discloses a manufacturing method for a polypyrrole cladded copper nanowire with high SPR effect. The manufacturing method comprises the following steps; utilizing a hydrothermal method to manufacture a copper nanowire, and dispersing the copper nanowire into a reagent; adding pyrrole, deionized water and hydrogen peroxide in sequence, and washing after stirring and centrifuging to obtain the polypyrrole cladded copper nanowire with high SPR effect. The polypyrrole cladded copper nanowire manufactured by the method has higher SPR effect. Moreover, the manufacturing method is simple in manufacturing, is low in cost, can realize batch production and does not affect physical properties of copper.

Description

technical field [0001] The invention relates to a method for preparing polypyrrole-wrapped copper nanowires, in particular to a method for preparing polypyrrole-wrapped copper nanowires with high SPR effect. Background technique [0002] Surface plasmon resonance (SPR) can cause high-density charge oscillations on the surface of materials, which significantly enhances the electromagnetic field strength and light absorption rate of the localized surface. The SPR effect of metal copper has been widely used in photovoltaic cells, photothermal therapy, photothermal catalysis and other fields. However, the current copper nanowire synthesis methods mainly include chemical vapor deposition, photolithography, and liquid phase synthesis. These synthesis methods often require high temperature and long reaction time, and have relatively high requirements for equipment. The cost of nanowire preparation and the difficulty of mass production. In addition, copper nanowires are easily oxi...
