Phase change materials exhibiting excellent heat storage property can be used for energy saving applications. The textile made by fiber with PCMs can provide human body a comfortable microenvironment. The heat-storage and thermo-regulated fiber with active poly (ethylene glycol) acrylate (PEGA) as phase change materials was prepared by reaction extrusion. Poly (ethylene glycol) acrylate was grafted to polypropylene (PP) during the extrusion process. Combining preparation with functionalization, this easy method makes the entire producing process more efficient and simple. We used nuclear magnetic resonance (NMR) and Fourier transform infrared spectroscopy (FT-IR) to characterize the structure of PEGA and PP-g-PEGA, and the results proved the synthesis of graft copolymer. Differential scanning calorimeter (DSC) was used for characterizing functional fibers thermal property. The fiber with fixed enthalpy provided heat storage and themo-regulated property. The melting and crystalline latent heat of best sample is 6.83J/g and 1.32J/g, respectively. The crystalline temperature region is from 41.67°C to 34.23°C, which is close to mean body temperature and it shows great potential in functional textile.

Selection Of

Esta investigación tiene como objetivo seleccionar un material de cambio de fase (PCM) que cumplen mejor la solución del almacenamiento de energía térmica entre 200-400 ° C y reducir el costo de producción. El uso de métodos multicriterios de toma de decisiones (MCMD) para la evaluación fueron proporcionales implementados como COPRAS-G, TOPSIS y VIKOR. La ponderación de los criterios se realizó por el método AHP (proceso analítico jerárquico) y los métodos de entropía. La correlación de los resultados entre los tres métodos de clasificación ha sido desarrollada por el coeficiente de correlación de Spearman. Los resultados ilustran el mejor y la segundo mejor opción para los tres MCDM fueron NaOH y KNO3. Además, tenía valores de correlación de Spearman entre los métodos excede de 0.714.
