Abstract

The invention belongs to the technical field of thin films, and relates to a method for preparing a flexible triboluminescence composite film; the method proposed by the invention is to sequentially vapor-deposit N2, N7-bis(1-naphthyl) on a polyethylene terephthalate substrate )‑N2, N7‑diphenylthianthracene‑2,7‑diamine layer, copper phthalocyanine layer, lithium fluoride layer, tris(4‑(N‑phenyl‑N‑(1‑naphthyl)amine group ) phenylphosphine layer, and then use ethylene-vinyl acetate copolymer plastics to obtain a flexible triboluminescence composite film, utilize the synergistic effect between each component in the composite structure, triboluminescence.Advantage of the present invention is: (1) triboluminescence The brightness reaches 90cd / m2, which is blue light; (2) After repeated rubbing for 50,000 times, the triboluminescent brightness only drops by 10%, which greatly improves the reliability of the triboluminescent composite film.

Description

technical field [0001] The invention belongs to the technical field of film materials, and in particular relates to a preparation method of a flexible triboluminescence composite film. Background technique [0002] Triboluminescence (Triboluminescence, TL) refers to the luminescence caused by mechanical pressure on certain solids. In a broad sense, it can also be called mechanical luminescence. In the process, such solid materials convert mechanical energy into light energy. Materials with triboluminescent properties can be used to prepare pressure-sensitive luminescent materials, and can be matched with photodetectors to prepare various forms of pressure detection sensors and display units in other scientific research devices, and can even be used in technical fields such as ultra-precision processing devices . In recent years, some complexes which have unique fluorescent properties and have been used to manufacture various fluorescent materials have been found to have t...
