Title:
METHOD FOR PREPARING CHIRAL METAL NANO SPIRAL FIBER ARRAY
Document Type and Number:
WIPO Patent Application WO/2020/113724
Kind Code:
A1
Abstract:
Provided is a method for preparing a chiral metal nano spiral fiber array capable of achieving fine structure regulation and not leaving organic matter such as templates; the method for preparation comprises the following steps: step S1: placing a substrate into an aminosilanization reagent and letting it stand for a period of time, then taking it out and washing it; step S2: immersing the substrate washed in step S1 in a solution containing a metal seed so as to load a metal seed; step S3: placing the substrate carrying the metal seed into a mixed solution containing a metal source and an inducer, and adding a reducing agent to perform a growth reaction for a predetermined time, thereby growing a metal spiral fiber array on the substrate; step S4: removing the remaining inducer from the metal spiral fiber array, the inducer being a chiral inducer.
