面向柔性可穿戴储能器件对集流体“高导电-高柔韧-高润湿”的综合需求,提出在水性介质中于碳纤维表面原位生长ZIF-67的界面工程策略。通过调控前驱体溶液的浓度与浸渍时间,在碳纤维上构建均一、致密且连续的ZIF-67覆盖层。采用扫描电子显微镜表征碳纤维复合材料的形貌与覆盖均匀性,采用X射线衍射仪、X射线光电子能谱仪分析晶相结构与化学价态,通过接触角与电流-电压曲线图分析碳纤维复合材料的润湿与导电特性。结果表明:浸渍时间6h、前驱体溶液浓度0.8mol/L时可获得最均一、致密且连续的沉积层。
To address the comprehensive requirements of flexible,wearable energy-storage devices for current collectors that combine high electrical conductivity,mechanical compliance,and strong electrolyte wettability,this study proposed an interfacial-engineering strategy for the in situ growth of ZIF-67 on carbon fibre (CF) substrates in an aqueous medium.By systematically tuning the precursor solution concentration and immersion duration,we constructed uniform,dense,and continuous ZIF-67 coatings on CFs.Scanning electron microscopy (SEM) was employed to characterise morphology and coverage uniformity.X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) were used to analyze the crystalline phase structure and cobalt valence state.Using contact-angle measurements and current-voltage curves evaluated the wettability and electrical transport characteristics of the CFs.The results demonstrated that an immersion time of 6 h and a precursor concentration of 0.8M yield the most uniform and continuous deposition layer.
