Abstract

A flexible nanocomposite holographic storage film, its preparation method and application relate to the field of holographic storage technology, and solve the problem that there is no preparation method for flexible devices capable of information storage. The steps are: preparing AgNO 3 solution and PVA solution and mixed at a volume ratio of 1:1-1.4 to obtain AgNO 3 / PVA mixed solution; prepare a tannic acid solution with a pH value of 8‑9, mix the tannic acid solution and AgNO 3 / PVA mixed solution to get AgNO 3 / PVA / TA mixed solution; take AgNO 3 / PVA / TA mixed solution is drop-coated on a bendable and colorless plastic substrate, and the plastic substrate is heated to form a film and realize Ag + Transformation to Ag NPs yields flexible Ag / PVA / TA nanocomposite films. The preparation method of the invention is simple and low in cost, and can obtain a flexible film with high diffraction efficiency, high absorption 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...
