三维(3D)电极材料因其独特的结构和优异的电化学性能而被认为是高性能超级电容器的理想候选者。纳米纤维素(CNF)和多壁碳纳米管(MWCNT)被广泛应用于电极材料的开发与设计,但如何利用它们独特的一维纳米结构和固有的物理特性来构筑高性能3D电极材料依然是一个巨大的挑战。采用“自下而上”的策略,以CNF/MWCNT冷冻干燥过程中自聚集形成的气凝胶薄片为填充物,镍泡沫(NF)的3D网状结构为骨架,巧妙构筑了一种具有独特“薄片填充-骨架支撑”结构的MWCNT/CNF-NF三维杂化材料。受益于NF三维骨架优异的导电性和增强作用及MWCNT/CNF气凝胶薄片高的比表面积,以MWCNT/CNF-NF为负载电活性物质聚吡咯(PPy)的平台,通过优化电沉积时间制备的PPy-MWCNT/CNF-NF自支撑电极具有良好的可弯曲性和优异的电化学特性。与预期一样,在5 mA·cm−2的电流密度下该电极的面积比容量高达2217.8 mF·cm−2 (869.9 F·g−1),经过3000次循环后依然具有90.2%的高容量保持率。 相似文献

Transparent electrodes attract intense attention in many technological fields, including optoelectronic devices, transparent film heaters and electromagnetic applications. New generation transparent electrodes are expected to have three main physical properties: high electrical conductivity, high transparency and mechanical flexibility. The most efficient and widely used transparent conducting material is currently indium tin oxide (ITO). However the scarcity of indium associated with ITO's lack of flexibility and the relatively high manufacturing costs have a prompted search into alternative materials. With their outstanding physical properties, metallic nanowire (MNW)‐based percolating networks appear to be one of the most promising alternatives to ITO. They also have several other advantages, such as solution‐based processing, and are compatible with large area deposition techniques. Estimations of cost of the technology are lower, in particular thanks to the small quantities of nanomaterials needed to reach industrial performance criteria. The present review investigates recent progress on the main applications reported for MNW networks of any sort (silver, copper, gold, core‐shell nanowires) and points out some of the most impressive outcomes. Insights into processing MNW into high‐performance transparent conducting thin films are also discussed according to each specific application. Finally, strategies for improving both their stability and integration into real devices are presented. 相似文献

As the demand for display technology in consumer electronics and lighting panels increases, thin, light, high‐quality, and more cost‐effective light‐emitting devices are required. Organic light‐emitting devices (OLEDs), satisfying the criteria exactly, have been considered the most promising next‐generation display and lighting technique. In particular, an OLED based on flexible substrate enables the device to be applied to curved displays, electronic newspapers, wearable displays, and conceptual lighting panels, has been always in the spotlight both in science and industry. Great advances on flexible OLEDs (FOLEDs) have been made over the past three decades. The fundamental elements of FOLEDs including substrates, electrodes, fabrication and encapsulation techniques, as well as the strategies of efficiency improvement are discussed herein. Moreover, emerging electrodes such as graphene, carbon nanotubes, metal nanowire network and their composite, flexible perovskite light emitting devices, and stretchable light emitting devices are also considered. Finally, the future challenges and prospects for these devices are put forward. 相似文献

It is of great challenge to develop a transparent solid state electrochromic device which is foldable at the device level. Such devices require delicate designs of every component to meet the stringent requirements for transparency, foldability, and deformation stability. Meanwhile, nanocellulose, a ubiquitous natural resource, is attracting escalating attention recently for foldable electronics due to its extreme flexibility, excellent mechanical strength, and outstanding transparency. In this article, transparent conductive nanopaper delivering the state‐of‐the‐art electro‐optical performance is achieved with a versatile nanopaper transfer method that facilitates junction fusing for high‐quality electrodes. The highly compliant nanopaper electrode with excellent electrode quality, foldability, and mechanical robustness suits well for the solid state electrochromic device that maintains good performance through repeated folding, which is impossible for conventional flexible electrodes. A concept of camouflage wearables is demonstrated using gloves with embedded electrochromics. The discussed strategies here for foldable electrochromics serve as a platform technology for futuristic deformable electronics. 相似文献

Compared to traditional , simple, planar or tubular flexible devices fabricated by spin‐coating, casting, or extrusion, 3D‐printed flexible electronic devices possess complicated geometries with precisely prescribed microarchitectures and excellent mechanical properties for satisfying all kinds of individual requirements. However, the full utilization of 3D‐printing technology to realize 3D‐printed flexible electronic devices remains limited by the flexibility and conductivity of 3D‐printing materials. To achieve 3D‐printed flexible electronic devices, the flexibility of 3D‐printed flexible devices and functionalization of conductive materials or hard silicon‐based electronic devices are combined. These 3D‐printed flexible electronic devices can be applied widely in the fields of personal wearable devices, prosthetic organs for the disabled, and human–computer interfaces. To further promote the rapid advent of 3D‐printed flexible electronic devices, the recent strategies and future developmental directions of fabricating these complex electronic devices are discussed here. 相似文献

A novel, green, and highly efficient strategy for room-temperature reduction of solid-state graphene oxide films has been successfully developed using hydrogen-involved reduction with the assistance of a small amount of Pd catalyst. Based on this approach, flexible reduced graphene oxide films with high conductivity can be achieved and a roll-to-roll technique is expected. 相似文献
