Abstract

Abstract An insulation network was constructed by adding hydroxyapatite nanowires (HNs) to a hydroxyethyl cellulose (HEC) system. The HNs improve the mechanical and insulating properties of the composites. The results showed the formation of strong chemical interactions between the HEC and HNs. Moreover, 20% HNs addition maximized the electrical insulation and tensile strength of the HEC/HNs film to 12.7 kV/mm and 34.12 MPa, respectively. Scanning electron microscopy revealed a three-dimensional network of HNs at the perforated edge of the films, which prevented further decomposition of HEC by the current flow. The superior mechanical properties of the combined HEC and HNs were attributed to the self-assembling cambium structure. Graphical Abstract

羟乙基纤维素与羟基磷灰石纳米线复合薄膜具有较高的机械强度和电绝缘性能

摘要将羟基磷灰石纳米线(HNs)添加到羟乙基纤维素(HEC)体系中，构建了一种绝缘网络。HNs提高了复合材料的力学性能和绝缘性能。结果表明HEC和HNs之间形成了强烈的化学相互作用。当HNs添加量为20%时，HEC/HNs膜的电绝缘强度和拉伸强度分别达到12.7 kV/mm和34.12 MPa。扫描电镜显示，在薄膜的穿孔边缘有一个三维网状的HNs，这阻止了电流对HEC的进一步分解。HEC和HNs复合材料优异的力学性能归因于其自组装形成层结构。图形抽象

期刊介绍： The Journal of Wood Chemistry and Technology (JWCT) is focused on the rapid publication of research advances in the chemistry of bio-based materials and products, including all aspects of wood-based polymers, chemicals, materials, and technology. JWCT provides an international forum for researchers and manufacturers working in wood-based biopolymers and chemicals, synthesis and characterization, as well as the chemistry of biomass conversion and utilization. JWCT primarily publishes original research papers and communications, and occasionally invited review articles and special issues. Special issues must summarize and analyze state-of-the-art developments within the field of biomass chemistry, or be in tribute to the career of a distinguished researcher. If you wish to suggest a special issue for the Journal, please email the Editor-in-Chief a detailed proposal that includes the topic, a list of potential contributors, and a time-line.
