Title:
RAMAN SCATTERING ENHANCEMENT SUBSTRATE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2020/121916
Kind Code:
A1
Abstract:
Provided is a Raman scattering enhancement substrate obtained by arranging, on a supporting base material, a plurality of columnar or massive porous carbon elements by means of a porous material having a carbon pore size of 10-50 nm in diameter. This substrate is produced by, for example: forming a polypyrrole nanoarray by filling a pyrrole as a monomer, into a template in which a plurality of columnar or cube-shaped holes are arranged using an anodic aluminum oxide; making the entirety of the polypyrrole nanoarray into a porous polypyrrole nanoarray with a diameter of 10-50 nm; and baking the resultant porous polypyrrole nanoarray.
