本文将氧化石墨烯(GO)、羧基化多壁碳纳米管(c-MWCNTs)等纳米碳材料通过水热的方法与氢氧化锂进行反应,得到碳基氢氧化锂化学蓄热复合材料.采用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射分析仪(XRD)以及热重/同步差热分析仪(TGA-DSC)等表征手段获取了复合材料的表观形貌、负载组分、蓄热密度等关键热物性参数.研究表明纳米碳材料的复合使LIOH的单体水合速率大幅度提升,与此同时蓄热密度有着不同程度地增大,其中以GO/LiOH复合材料的化学蓄放热性能最为突出。除此之外,材料整体的导热系数也由于GO的复合有着显著的提高.本研究拓展了碳材料在储能领域的应用范围,针对纳米碳化学蓄热复合材料提供了理性的设计方法。 |

LiOH·H_2O nanoparticles supported on grapheneoxide (GO) and carboxylic multi wall-carbon nano tubes (c-MWCNTs) were facilely synthesized by a hydrothermal process. The pivotal thermophysical property of nanocomposites was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray powder diffraction (XRD) and thermogravimetry-differential thermal analysis (TGA-DSC). The as-prepared sample of LiOH/nano carbonexhibited higher rate of heat release than pure lithium hydroxide and showed a greatly enhanced thermal energy storage density, especially for LiOH/GO. In addition,the introduction of GO also improved the thermal conductivity of composites. The research expandedcarbon materials' scope of application in the thermal storagefield and proposed the new concept ofdesigning rationally nano carbon-based composite materials for low-temperature chemical heat storage. |
