纳米固色剂Tinokin VG在灯芯绒上的应用探讨

由于灯芯绒产品的特殊性(色泽深浓色多,绒面使摩擦系数增大),灯芯绒织物的摩擦牢度难以提高到较满意的程度。使用Tinokin VG30～40g/L进行浸轧、烘干、焙烘后,可使硫化染料染色的黑色灯芯绒的干、湿摩擦牢度从1～2级和1级分别提高至4级和3级;使活性染料染色的咖啡色及黑色灯芯绒的干、湿摩擦牢度从2级和1～2级分别提高至4级和3级。     

Recent Advances in Metal Oxide‐based Electrode Architecture Design for Electrochemical Energy Storage

Metal oxide nanostructures are promising electrode materials for lithium‐ion batteries and supercapacitors because of their high specific capacity/capacitance, typically 2–3 times higher than that of the carbon/graphite‐based materials. However, their cycling stability and rate performance still can not meet the requirements of practical applications. It is therefore urgent to improve their overall device performance, which depends on not only the development of advanced electrode materials but also in a large part “how to design superior electrode architectures”. In the article, we will review recent advances in strategies for advanced metal oxide‐based hybrid nanostructure design, with the focus on the binder‐free film/array electrodes. These binder‐free electrodes, with the integration of unique merits of each component, can provide larger electrochemically active surface area, faster electron transport and superior ion diffusion, thus leading to substantially improved cycling and rate performance. Several recently emerged concepts of using ordered nanostructure arrays, synergetic core‐shell structures, nanostructured current collectors, and flexible paper/textile electrodes will be highlighted, pointing out advantages and challenges where appropriate. Some future electrode design trends and directions are also discussed.

Flexible Hybrid Paper Made of Monolayer Co3O4 Microsphere Arrays on rGO/CNTs and Their Application in Electrochemical Capacitors

A facile one‐step hydrothermal method is developed for large‐scale production of well‐designed flexible and free‐standing Co₃O₄/reduced graphene oxide (rGO)/carbon nanotubes (CNTs) hybrid paper as an electrode for electrochemical capacitors. Densely packed unique Co₃O₄ monolayer microsphere arrays uniformly cover the surface of the rGO/CNTs film. The alkaline hydrothermal treatment leads to not only the deposition of Co₃O₄ microspheres array, but also the reduction of the GO sheets at the same time. The unique hybrid paper is evaluated as an electrode for electrochemical capacitors without any ancillary materials. It is found that the obtained hybrid flexible paper, composed of Co₃O₄ microsphere array anchored to the underling conductive rGO/CNTs substrate with robust adhesion, is able to deliver high specific capacitance with excellent electrochemical stability even at high current densities, suggesting its promising application as an efficient electrode material for electrochemical capacitors.
