Title:
SURFACE-ENHANCED RAMAN SCATTERING COMPOSITE SUBSTRATE, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/082952
Kind Code:
A1
Abstract:
The present invention relates to the technical field of Raman detection. Disclosed are a surface-enhanced Raman scattering composite substrate, and a preparation method therefor and a use thereof. The preparation method comprises the following steps: dissolving cyanamide salt and poly(3-hexylthiophene) in a solvent to obtain a mixed solution; and coating the mixed solution on a glass sheet, and drying same to obtain a composite substrate; wherein the cyanamide salt is selected from at least one of silver cyanamide, zinc cyanamide and silver dicyandiamide. Poly(3-hexylthiophene) and the cyanamide salt are selected to prepare a composite film to serve as the surface-enhanced Raman scattering composite substrate, and the composite substrate layer is used in Raman spectrum detection, has high detection sensitivity, strong stability and strong reusability, and can be widely used in the detection of organic dye molecules, such as methylene blue, crystal violet or azure I. The composite substrate provided by the present invention has low preparation costs and simple preparation method.
