The lightweight, flexible, high-performance electrothermal material is in high demand in object thermal management. Graphene glass fiber fabric (GGFF) is characterized by excellent electrical conductivity, light weight, and high flexibility, showing superiorities as an electrothermal material. However, the traditional single-carbon-precursor chemical vapor deposition (CVD) graphene growth strategy commonly suffers from the severe thickness nonuniformity of the large-sized graphene film along the gas-flowing direction. Herein, a complementary CVD graphene growth strategy based on the simultaneous introduction of high- and low-decomposition-energy-barrier mixed carbon precursors is developed. In this way, the large-area uniform GGFF with a dramatically decreased nonuniformity coefficient is fabricated (0.260 in 40 cm × 4 cm). GGFF-based heater presents a widely tunable temperature range (20–170 °C) at low working voltage (<10 V) and uniform large-area heating temperature (171.4 ± 3.6 °C in 20 cm × 15 cm), which realizes remarkable anti/deicing performances under the low energy consumption (fast ice melting rate of 79 s mm⁻¹ under a low energy consumption of 0.066 kWh mm⁻¹ m⁻²). The large-area uniform GGFF possesses substantial advantages for applications in thermal management, and the complementary CVD fabrication strategy shows reliable scalability and universality, which can be extended to the synthesis of various materials.

大面积均匀石墨烯玻璃纤维织物的互补化学气相沉积制备

轻质、灵活、高性能的电热材料在物体热管理中的需求量很大。石墨烯玻璃纤维织物（GGFF）具有导电性好、重量轻、柔韧性高等特点，显示出作为电热材料的优越性。然而，传统的单碳前体化学气相沉积（CVD）石墨烯生长策略普遍存在大尺寸石墨烯薄膜沿气体流动方向的严重厚度不均匀性问题。在此，开发了一种基于同时引入高分解能垒和低分解能垒混合碳前驱体的互补 CVD 石墨烯生长策略。通过这种方式，可以制造出不均匀系数显着降低的大面积均匀 GGFF（0.260 in 40 cm × 4 cm）。^{-1在 0.066 kWh mm}^-1 m ^-2的低能耗下）。大面积均匀GGFF在热管理应用方面具有显着优势，互补的CVD制造策略显示出可靠的可扩展性和通用性，可扩展到各种材料的合成。
