| titleOfInvention | A kind of thin film material with both heat absorption/wave absorption dual-effect function and preparation method thereof |
| abstract | The invention discloses a film material with both heat-absorbing/wave-absorbing dual-effect functions and a preparation method thereof. The composite film material is a water-soluble polymer, such as polyvinyl alcohol (PVA), sodium cellulose, gelatin, etc. It is the shell layer, the phase change material polyethylene glycol (PEG) is used as the core layer, and the magnetic nanoparticles, such as metal (Fe, Co, Ni), metal alloy (FeCo), metal oxide (Fe 3 O 4 , NiO) , CoFe 2 O 4 ), etc. are absorbing fillers, which are prepared by coaxial electrospinning. The invention is characterized in that water is used as the spinning solvent, and the prepared fiber has a core-shell structure, which overcomes the problem of easy leakage when the phase-change core layer undergoes solid-liquid phase transition, and has a high content of the phase-change core layer. In addition, the magnetic nanoparticles themselves have a high magnetic loss tangent angle, which can be used for the absorption and attenuation of electromagnetic waves. Therefore, the prepared composite film material has the advantages of green preparation process, high latent heat of phase transition, good electromagnetic wave absorption performance, stable recycling performance, etc., and can simultaneously meet the multifunctional application requirements of heat absorption/wave absorption of film materials. |
