Abstract

In this study, carbon nanotube (CNT)/carbon nanofiber (CNF) composite electrothermal films were prepared by electrospinning, and the effects of the CNT content and carbonization temperature on the electrothermal properties of the CNT/CNF composite films were investigated. The experimental results demonstrated that the conductivity of the CNT/CNF composite electrothermal film (0.006-6.89 S/cm) was directly affected by the CNT content and carbonization temperature. The electrothermal properties of the CNT/CNF positively correlated with the CNT content, carbonization temperature, and applied voltage. The surface temperature of CNT/CNF can be controlled within 30-260 °C, and continuously heated and cooled 100 times without any loss. The convective heat transfer with air is controllable between 0.008 and 31.75. The radiation heat transfer is controllable between 0.29 and 1.92. The prepared CNT/CNF exhibited a heat transfer efficiency of up to 94.5%, and melted a 1 cm thick ice layer within 3 min by thermal convection and radiation alone.

通过电纺丝技术将碳纳米管/碳纳米纤维复合材料制成的高质量导电网络薄膜用于电热应用。

本研究采用电纺丝法制备了碳纳米管（CNT）/碳纳米纤维（CNF）复合电热膜，并研究了CNT含量和碳化温度对CNT/CNF复合电热膜电热性能的影响。实验结果表明，CNT/CNF 复合电热膜的电导率（0.006-6.89 S/cm）直接受 CNT 含量和碳化温度的影响。CNT/CNF 的电热性能与 CNT 含量、碳化温度和外加电压呈正相关。CNT/CNF 的表面温度可控制在 30-260 °C 之间，并可连续加热和冷却 100 次而无任何损失。与空气的对流换热可控制在 0.008 至 31.75 之间。辐射传热可控制在 0.29 至 1.92 之间。所制备的 CNT/CNF 的传热效率高达 94.5%，仅通过热对流和辐射就能在 3 分钟内融化 1 厘米厚的冰层。

期刊介绍： Nanomaterials (ISSN 2076-4991) is an international and interdisciplinary scholarly open access journal. It publishes reviews, regular research papers, communications, and short notes that are relevant to any field of study that involves nanomaterials, with respect to their science and application. Thus, theoretical and experimental articles will be accepted, along with articles that deal with the synthesis and use of nanomaterials. Articles that synthesize information from multiple fields, and which place discoveries within a broader context, will be preferred. There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental or methodical details, or both, must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Nanomaterials is dedicated to a high scientific standard. All manuscripts undergo a rigorous reviewing process and decisions are based on the recommendations of independent reviewers.
