In order to ensure the operational reliability and infor-mation security of sophisticated electronic components and to protect human health,efficient electromagnetic interference(EMI)shielding materials are required to attenuate electromagnetic wave energ
Combining with the advantages of two-dimensional(2D)nanomaterials,MXenes have shown great potential in next generation rechargeable batteries.Similar with other 2D materials,MXenes generally suffer severe self-agglomeration,low capacity,and unsatisfied du
通过真空蒸镀技术、静电纺丝技术和湿法腐蚀法成功制备出铜纳米线网络透明电极。首先优化纺丝条件,制备出均匀的聚丙烯腈(PAN)纳米纤维,然后将PAN纳米纤维作为掩模腐蚀铜膜得到铜纳米线网络透明电极。通过对纺丝时间、纺丝接收取向、蒸气处理时间和湿法腐蚀时间等制备条件进行优化,得到表面光滑连续、形貌良好的铜纳米线网络透明电极。利用紫外-可见分光光度计、光学显微镜、表面低电阻测试仪和扫描电子显微镜(SEM)等测试仪器对透明电极的性能进行了分析和讨论。研究发现:纺丝1 min、交叉接收PAN纳米纤维、蒸气处理30 s
Zn-ion hybrid supercapacitors(SCs)are considered as prom-ising energy storage owing to their high energy density compared to tradi-tional SCs.How to realize the
