Abstract

The invention discloses a preparation method for a zinc oxide nanoflower / nanogold composite based temperature sensitive imprinted polymer. The method includes the following steps: preparing a zinc oxide nanoflower, and preparing a zinc oxide nanoflower modified electrode; taking the zinc oxide nanoflower modified electrode as a working electrode, taking a saturated calomel electrode as a referenceelectrode, and taking a platinum filament as a counter electrode so that a zinc oxide nanoflower / nanogold composite modified electrode can be obtained; and self-assembling a bromine-containing compound on a sulfydryl sealing end on the surface of the zinc oxide nanoflower / nanogold composite modified electrode, forming a bromine-containing compound modified zinc oxide / nanogold composite modified electrode, preparing a polymer modified zinc oxide nanoflower / nanogold composite modified electrode to take out, removing template molecules in the polymer, and performing natural air drying after thewashing of ultrapure water so that a zinc oxide nanoflower / nanogold composite based temperature sensitive imprinted polymer can be obtained.

Description

technical field [0001] The invention discloses a temperature-sensitive imprinted polymer, in particular a method for preparing a temperature-sensitive imprinted polymer based on zinc oxide nanoflower / nano-gold composite, which is simple in operation, low in cost, temperature responsive and high in sensitivity. Background technique [0002] As a new type of material with the most potential, nanomaterials have developed rapidly in a short period of time. The structural unit size of nanomaterials is between 1 and 100 nm. Compared with ordinary materials, nanomaterials have many excellent properties, such as large specific surface area, increased conductivity, and changes in physical properties. ZnO, as an n-type semiconductor, has been widely used in various device applications. Due to its unique crystallinity, various morphologies can be easily synthesized, including nanorods, nanosheets, porous hollow spheres, etc. Nanoflowers composed of nanorods have large porosity and la...
