Abstract

The invention discloses a flexible nano-composite holographic storage film, and a preparation method and an application thereof, and relates to the technical field of holographic storage. The purposeof the invention is to solve the problems of preparation methods of flexible devices being unable to store information. The preparation method comprises the following steps: preparing a AgNO3 solutionand a PVA solution, and mixing the AgNO3 solution with the PVA solution according to a volume ratio of 1:(1.1-1.4) to obtain a AgNO3 / PVA mixed solution; preparing a tannic acid solution having a PH value of 8.9, and mixing the tannic acid solution with the AgNO3 / PVA mixed solution to obtain a AgNO3 / PVA / TA mixed solution; and dispensing the AgNO3 / PVA / TA mixed solution on a bendable colorless plastic substrate, and heating the plastic substrate to form a film and realize the conversion of Ag<+> into Ag NPs in order to obtain the flexible Ag / PVA / TA nano-composite film. The preparation method ofthe invention has the advantages of simplicity, low in cost, and obtaining of the flexible film with a high diffraction efficiency and a high absorbance and suitable for holographic storage.

Description

technical field [0001] The invention relates to the technical field of holographic storage, in particular to a flexible nanocomposite holographic storage film, a preparation method and application of the film. Background technique [0002] In the fields of wearable medical care, electronic skin, and intelligent robots in the future, flexible electronic technology has broad application prospects, and has received extensive attention and research from academia and industry. In flexible electronic systems, flexible memory is an important part, and the way of information and data storage has also changed. At present, storage technology is divided into three main aspects: semiconductor storage, magnetic storage and optical storage. As a special storage method in optical storage—holographic storage, due to its different physical mechanism of storage, it breaks through the storage limit of traditional optical storage, and has become a A new storage method has been widely concerne...
