Abstract

The invention relates to preparation of a nano-fiber bundle transistor and application of the nano-fiber bundle transistor in ion sensing. The high-performance nano-fiber bundle transistor is prepared by polymerizing pyrrole monomers on a nano-fiber bundle in situ, and the nano-fiber bundle transistor is applied in an ion concentration sensor. Polypyrrole has good chemical and thermodynamic stability, biocompatibility and electric conduction performance, nano-fiber has stitchability, high specific surface area and high surface activity, and can be used for preparation and application of the high-performance transistor. The preparation method is simple in process, gentle in reaction condition, low in production cost, free of pollution and suitable for preparing the nano-fiber bundle transistor on a large scale, and has great application potential in electronic microcircuits.

Description

technical field [0001] The invention relates to the preparation of a nanofiber bundle-based transistor and its application in ion sensors, belonging to the technical field of electronic information. Background technique [0002] Nanofiber refers to a linear material with a diameter of nanoscale and a large length. Due to its small size effect, surface effect and high adsorption, it has a wide range of uses. For example, nanofibers are implanted on the surface of a fabric to form a layer of Stable gas film, made of amphiphobic interface fabric, which can not only waterproof, but also oil-proof and anti-fouling; advanced protective clothing made of nanofibers, the fabric is porous and has a membrane, which not only allows air to pass through, but also has It is breathable, can also block wind and filter fine particles, has barrier properties to aerosols, and can prevent biological and chemical weapons and toxic substances. In addition, nanofibers can also be used for purifica...
