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 invention discloses nano phase change and energy storage luminescent fibers. The nano phase change and energy storage luminescent fibers comprise the following components: 50%-100% of a polyurethane solid-solid phase change material and 0%-50% of polymethyl methacrylate; the mass content of the components is 100%; and a benzoic acid ternary rare earth luminescent material accounts for 10%-30% of the total mass based on the total amount of the components. The invention further discloses a preparation method of the nano phase change and energy storage luminescent fibers. The polyurethane solid-solid phase change material is used as a fiber forming polymer and the benzoic acid ternary rare earth luminescent material is used as the luminescent material; ethyl acetate and N,N-dimethylformamide are used as compound solvents; and the phase change and energy storage luminescent fibers with the diameters being 30nm-100nm are prepared by an electrostatic spinning technology. The phase change luminescent fibers have the characteristics of high phase transformation enthalpy value in heat storage and releasing, high phase transformation speed, stable luminescent performance, long fluorescence service life and the like; and the phase change luminescent fibers can be widely applied to the fields of medicine and health, electronic information clothing and the like.

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...
