Graphene chemical vapor deposition (CVD) growth directly on target using substrates presents a significant route toward graphene applications. However, the substrates are usually catalytic-inert and special-shaped; thus, large-scale, high-uniformity, and high-quality graphene growth is challenging. Herein, graphene-skinned glass fiber fabric (GGFF) was developed through graphene CVD growth on glass fiber fabric, a Widely used engineering material. A fluid dynamics rectification strategy was first proposed to synergistically regulate the distribution of carbon species in 3D space and their collisions with hierarchical-structured substrates, through which highly uniform deposition of high-quality graphene on fibers in large-scale 3D-woven fabric was realized. This strategy is universal and applicable to CVD systems using various carbon precursors. GGFF exhibits high electrical conductivity and photothermal conversion capability, based on which a natural energy harvester was first developed. It can harvest both solar and raindrop energy through solar heating and droplet-based electricity generating, presenting promising potentials to alleviate energy burdens.
在目标衬底上直接进行石墨烯化学气相沉积（CVD）生长是实现石墨烯应用的重要途径。然而，衬底通常具有催化惰性且形状特殊，因此大规模、高均匀性和高质量的石墨烯生长具有挑战性。在此，通过在广泛使用的工程材料玻璃纤维织物上进行石墨烯CVD生长，制备了石墨烯包覆玻璃纤维织物（GGFF）。首次提出了一种流体动力学整流策略，以协同调节三维空间中碳物种的分布及其与分级结构衬底的碰撞，从而实现高质量石墨烯在大规模三维机织物纤维上的高度均匀沉积。该策略具有通用性，适用于使用各种碳前驱体的CVD系统。GGFF具有高导电性和光热转换能力，基于此首次开发了一种自然能量收集器。它可以通过太阳能加热和基于水滴的发电来收集太阳能和雨滴能量，在减轻能源负担方面展现出广阔的应用潜力。
