Abstract

The invention belongs to the fields of research and development of new materials, and specifically relates to a bamboo fiber and polyaniline composite phase-change energy storage material and an preparation and an application thereof. The composite phase-change energy storage material provided by the invention comprises the following raw materials in parts by weight: 30 to 80 parts by weight of bamboo fiber, 10 to 20 parts by weight of chlorine salt, 20 to 50 parts by weight of carbonate, 10 to 30 parts by weight of a reducing agent, 10 to 40 parts by weight of aniline and 10 to 30 parts by weight of an oxidizing agent. The composite phase-change energy storage material provided by the invention has the advantages of proper phase-change temperature, large thermal conductivity and high energy storage density.

Description

technical field [0001] The invention belongs to the field of research and development of new materials, in particular to a bamboo fiber and polyaniline composite phase change energy storage material and its preparation and application. Background technique [0002] Bamboo fiber is a cellulose fiber extracted from naturally growing bamboo, and it is the fifth largest natural fiber after cotton, hemp, wool and silk. Bamboo fiber has the characteristics of good air permeability, instant water absorption, strong wear resistance and good dyeability, and has natural antibacterial, antibacterial, anti-mite, deodorant and anti-ultraviolet functions. The chemical components of bamboo fiber are mainly cellulose, hemicellulose and lignin, all of which belong to high polysaccharides, and the total amount accounts for more than 90% of the dry mass of the fiber, followed by protein, fat, pectin, tannin, pigment, Ash, etc., mostly exist in the intracellular cavity or special organelles, d...
