Nghiên cứu tổng hợp, đặc trưng và ứng dụng màng chitosan ‐ ferrite từ tính có cấu trúc quang học

In this work, iridescent chiral nematic mesoporous chitosan nanofibers are used as scaffolds to fabricate composite materials resemble magnetic photonic paper‐like membrane. The thermal removal of the chitosan template in the composites affords spinel CoFe2O4 nanostructures. These resulting materials are characterized by using Scanning electron microscope (SEM), Powder X‐ray diffraction (XRD), Infrared spectroscopy (IR), and Vibrating Sample Magnetometer (VSM). The application of the ferrite/chitosan composites and the calcined ferrite nanomaterials are further proved by investigating the adsorption capacity of methylene blue in aqueous media.
