摘要

黄麻是一种廉价的、可生物降解的、环保的天然纤维，在包装材料、家纺、保温材料、地坪材料、土工复合材料、医疗卫生等方面具有独特的应用潜力。为了扩大黄麻纤维的应用范围，在一个密封的不锈钢高压灭菌器中，在650±50°C下进行简单的无溶剂高温碳化，然后冷却，试图制备轻质碳超细纤维。加热-冷却循环重复10次，不进行任何化学活化。碳纤维的体积密度为0.2609 g cm−3，颗粒密度为4.02 g cm−3，中空度/孔隙度为93.51%。扫描电镜图像显示了多通道中空结构的存在，布鲁诺尔-埃米特-泰勒（BET）表面测量显示为介孔表面。经高温炭化处理后，原黄麻纤维的总平均直径由79.7 μm下降到6.7 μm左右。所制备的碳纤维被命名为多通道中空碳纤维（MCHCMF）。少数微纤维沿纵轴还含有单个空心。MCHCMF的表面表征证实了含-OH、CO、-CH2和C-O-C基团氧的还原和CC环结构的增强。不同的有机溶剂和表面活性剂在MCHCMF上的吸附表现出显著的吸附行为，这是因为MCHCMF具有较大的比表面积和中空介孔结构。因此，这种MCHCMF可以应用于环境修复，储能，催化，脱色以及广泛的行业，从膜，垫子到化学和制药行业。

Multi-channel hollow carbon microfiber from raw jute fiber: Solvent free synthesis and characterization

Jute is a cheap source of biodegradable and environment friendly natural fiber that possesses unique application potential in packaging material, home textiles, insulation material, floor coverings, geo-composites, medical and health related products. In order to amplify the applications of jute fiber, preparation of light-weight carbon microfiber is attempted via a simple solvent-free high temperature carbonization in a sealed stainless autoclave at 650 ± 50 °C followed by cooling. The heating-cooling cycle is repeated 10 times without any chemical activation. The bulk density, particle density and hollowness/porosity of as-prepared carbon fiber are 0.2609 g cm⁻³, 4.02 g cm⁻³, and 93.51 % respectively. Scanning electron microscopic images revealed the presence of multi-channel hollow structure and Brunauer–Emmett–Teller (BET) surface measurement indicated mesoporous surface. The overall average diameter of raw jute fiber (RJF) is declined from 79.7 μm to around 6.7 μm after high temperature carbonization. The as prepared carbon fiber is named as multi-channel hollow carbon microfiber (MCHCMF). Few of the microfibers also contained single hollow along the longitudinal axis. Surface characterization of MCHCMF confirmed the reduction of oxygen containing -OH, CO, -CH₂ and C-O-C groups and enhancement of CC ring structure. The sorption behavior of different organic solvents and surfactants on MCHCMF displayed significant sorption because of large specific surface area and mesoporous hollow structure. Hence, such MCHCMF can be applied in environmental restoration, energy storage, catalysis, decolorizer and in wide range of industries ranging from membrane, mat to chemical and pharmaceutical industries.

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
