Embodiment 1

[0032] Example 1: Preparation of organic film-coated immobilized nanowires

[0033] The first immobilized nanowire of the present invention is an organic film-coated immobilized nanowire. Film-forming organic matter can be used in this embodiment. By selecting an appropriate film-forming method, the coated and immobilized nanowires of the present invention can be prepared to achieve the purpose of the present invention. The organic matter that can form a film includes any organic matter that does not contain particles with a particle size greater than 100 nm and can form a complete or incomplete film with a thickness of less than 100 nm on the above-mentioned nanowire or / and carrier. In this embodiment, the organic film preferably contains an organic film, more preferably an organic coating film containing crosslinking molecules. In this embodiment, the coating that can be formed by the coating used can be one of the following according to its anti-pollution properties: hydro...

Embodiment 2

[0036] Example 2: Preparation of immobilized nanowires coated with polymer adsorption layer

[0037] The second coated and immobilized nanowire of the present invention is a polymer adsorption layer coated and immobilized nanowire. Polymers that can be adsorbed by nanowires or / and carriers can be used in this embodiment. By selecting an appropriate adsorption method, the coated and immobilized nanowires of the present invention can be prepared to achieve the purpose of the present invention. The polymer includes any one that can form a complete or incomplete adsorption layer with a thickness of less than 100 nm on the above-mentioned nanowire or / and carrier. In this embodiment, the polymer used is preferably a polymer adsorbent containing an adsorption group. The adsorption groups include ionic groups, affinity groups, hydrophobic or / and oleophobic groups, and the like. In order to make the prepared coated and immobilized nanowires have special properties, other functional g...

Abstract

The invention discloses an immobilized nanometer wire, the device and a process for preparation, which relates to an immobilized nanometer wire at least comprising a carrier, a nanometer wire fixed on the carrier, a coating of the nanometer wire or / and a coating on the carrier, wherein the coating has a single layer or multiple layers. The invention also relates to the device of the immobilized nanometer wire and a process for preparing the immobilized nanometer wire, which at least includes (1) preparing the nanometer wire, (2) coating the prepared nanometer wire or / and the surface of the carrier fixed with the nanometer wire by using coating materials. The invention has the advantages that compared with the uncoated immobilized nanometer line, the coated immobilized nanometer wire of the invention is more robust, for example, the invention has higher stability, applicability, adaptability or / and anti-pollution property. The nanometer device of the invention not only has better robust property, but also has better properties, such as better sensibility.

Description

technical field [0001] The invention relates to an immobilized nanowire, a device containing the immobilized nanowire, and a preparation method of the immobilized nanowire. Background technique [0002] At present, more and more immobilized nanowire schemes have been disclosed (for example, US patents 6248674, 6720240; European patent application EP1725189; US patent application US2006255481, etc.). However, before the large-scale application of immobilized nanowires, there are still some urgent problems to be solved, such as the stability of immobilized nanowires, adaptability to applications, and anti-pollution properties. Contents of the invention [0003] The purpose of the present invention is to improve the reliability (Robust) of preparation and use of immobilized nanowires. The anti-pollution property of the wire; in particular, it involves improving the stability of the combination of the nanowire and the carrier, the stability of the structure of the nanowire it...
