Abstract

This research aims to develop and investigate novel Nano-enhanced phase change materials (NEPCMs) capable of meeting the temperature requirements for vaccine transportation within the range of 0–10 °C. Phase change materials (PCMs) can store energy in the form of latent heat and demonstrate outstanding chemical and thermal stability, which makes them promising for thermal energy storage (TES) applications. However, their limited thermal conductivity reduces the rate of heat transfer during energy storage and release. The present study utilised 1-Decanol (DA) as PCM and to improve the thermal conductivity, graphene nanoplatelets (GN) were added at different weight percentages of 0.5 %, 1 % and 1.5 % to develop NEPCMs. Pure DA exhibits an onset melting temperature (T_OM) of 4.05 °C and a melting enthalpy (H_m) of 220.09 Jg⁻¹. After adding 1.5 % GN a 32.67 % increase in thermal conductivity from the base DA. The phase change characteristics, chemical stability and thermal stability of the NEPCMs are evaluated using differential scanning calorimetry (DSC), fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). Additionally, the samples underwent 500 heating and cooling cycles to ensure their thermal stability and the samples displayed good thermal and chemical stability. Hence, the prepared NEPCMs exhibit significant potential in cold chain logistics.

用于冷链的新型纳米颗粒增强相变材料的开发、热物理特性和实验性能评估

本研究旨在开发和研究能够满足0-10°C范围内疫苗运输温度要求的新型纳米增强相变材料（NEPCMs）。相变材料（PCMs）可以以潜热的形式储存能量，并表现出出色的化学和热稳定性，这使得它们在热能储存（TES）应用中具有前景。然而，它们有限的导热性降低了能量储存和释放过程中的传热速率。本研究利用1-癸醇（DA）作为PCM，为了提高导热性，在nepcm中添加了不同重量百分比的石墨烯纳米片（GN），分别为0.5%、1%和1.5%。纯DA的起始熔化温度（TOM）为4.05℃，熔化焓（Hm）为220.09 Jg−1。加入1.5% GN后，导热系数比碱DA提高32.67%。采用差示扫描量热法（DSC）、傅里叶红外光谱（FTIR）和热重分析（TGA）对nepcm的相变特性、化学稳定性和热稳定性进行了评价。此外，样品经过500次加热和冷却循环以确保其热稳定性，样品具有良好的热稳定性和化学稳定性。因此，制备的nepcm在冷链物流中表现出巨大的潜力。

期刊介绍： International Journal of Thermophysics serves as an international medium for the publication of papers in thermophysics, assisting both generators and users of thermophysical properties data. This distinguished journal publishes both experimental and theoretical papers on thermophysical properties of matter in the liquid, gaseous, and solid states (including soft matter, biofluids, and nano- and bio-materials), on instrumentation and techniques leading to their measurement, and on computer studies of model and related systems. Studies in all ranges of temperature, pressure, wavelength, and other relevant variables are included.
