Abstract

The invention discloses a silicon nanometer wire-conductive polymer PEDOT (polyethylenedioxythiophene) compound as well as a preparation method and an application thereof. The preparation method comprises the following steps: 1) using an HF (Hydrogen Fluoride) solution to treat the surface of a silicon nanometer wire array structure which is acquired by using a metal nanometer particle catalyzing auxiliary etching method, thereby acquiring a treated silicon nanometer wire array structure; and 2) using a cyclic voltammetry to enable a polymer monomer EDOT (ethylenedioxythiophene) to have electrochemical polymerization on the surface of the treated silicon nanometer wire array structure, thereby acquiring a silicon nanometer wire-conductive polymer compound. The preparation method has a mild reaction condition, is easily operated and can be used for efficiently controlling the thickness of functional polymers on the silicon nanometer wire surface, the band structure and the conductivity. The preparation method is an effective method for constructing a compound structure of the silicon nanometer wire-conductive polymer functional compound. The application of the acquired compound structure in the field of photocatalytic hydrogen production is researched and a result shows that the compound structure has high catalytic property.

Description

technical field

[0001] The invention relates to a silicon nanowire-conductive polymer composite and a preparation method and application thereof. Background technique

[0002] Silicon is the basic material of the modern information technology industry, and silicon nanowires are considered to be an important building block for future silicon-based nanodevices.

[0003] For silicon nanomaterials, based on its particularity in device applications, it is necessary to study the effect of chemical modification on the performance of silicon nanomaterial-based devices. As device size shrinks further, the effects caused by surface state changes will become more critical. For nanodevices, this surface state often plays a decisive role in the performance of the device. The limitations of the silicon material itself, such as poor chemical stability and easy aggregation, further enhance the necessity of chemical modification. In sensing and electrical applications, the surface effect ...
