Problems solved by technology

However, due to high-temperature melting processing, it is easy to discolor and decompose, it is difficult to disperse uniformly when directly blended with polymers, the addition amount is low, the fluorescence intensity decreases, and the color purity decreases in different temperature environments. The application of luminescent color-changing materials and fluorescent anti-counterfeiting fibers is limited.

Abstract

The nanometer phase-change energy storage luminescent fiber disclosed in the present invention comprises: polyurethane solid-solid phase change material 50%-100%; polymethyl methacrylate 0%-50%, the mass content of the above components is 100%; Based on the total amount of the above components, the benzoic acid ternary rare earth luminescent material accounts for 10%-30% of the above total mass. The invention also discloses a method for preparing a nanometer phase change energy storage luminescent fiber, which uses a polyurethane solid-solid phase change material as a fiber-forming polymer, a benzoic acid ternary rare earth complex as a luminescent material, and ethyl acetate and N , N-dimethylformamide is a composite solvent, and a phase-change energy storage luminescent fiber with a diameter of 30-100 nm is prepared by electrospinning technology. The phase-change light-emitting fiber has the characteristics of high phase-transition enthalpy for thermal energy storage and release, fast phase transition rate, stable luminescence performance, and long fluorescence lifetime, and can be widely used in medical and health, electronic information clothing and other fields.

Description

technical field [0001] The invention belongs to the field of functional fibers, and in particular relates to a nano phase change energy storage luminescent fiber, and also relates to a preparation method of a nano phase change energy storage luminescent fiber. Background technique [0002] Phase change energy storage material is a functional material that can store excess heat energy through phase change and release it when needed. Based on the thermal energy storage and release function, it can intelligently regulate the surrounding ambient temperature to keep it in a constant temperature range. The phase change energy storage fibers that have been reported so far are mainly blending phase change materials with a phase change energy storage function with fiber-forming polymers, and the obtained phase change fibers have a low phase change enthalpy. However, the recently reported polyurethane-based solid-solid phase change materials that can be directly melt-processed have l...
