Complementary Chemical Vapor Deposition Fabrication for Large‐Area Uniform Graphene Glass Fiber Fabric

Abstract

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.

Scalable Fabrication of Dual‐Function Fabric for Zero‐Energy Thermal Environmental Management through Multiband, Synergistic, and Asymmetric Optical Modulations

“…As demonstrated in our previous study, [ 34,35 ] GGFF obtained by chemical vapor deposition (CVD) growth of graphene on glass fiber fabric exhibits high mid‐IR emissivity (≈0.92 in 2.5–20 µm) (Figures S1 and S2, Supporting Information). Therefore, the GGFF was chosen as the infrared emitter, as well as the skeleton of the sandwich structure of the dual‐function fabric.…”

Functional Textiles with Smart Properties: Their Fabrications and Sustainable Applications

“…CVD: Due to precise and real-time control of the coating thickness and structure as well as adaptability on arbitrary substrates, CVD has been widely employed to functionalize the textiles for wearable devices. [250,251] The controlled deposition thickness is making CVD become an ideal strategy for the ultrathin durable and breathable coating of smart fabrics or intelligent clothing (Figure 6b). Soto et al utilized initiated CVD to deposit the conformal short fluorinated polymers onto polyester fabrics, which exhibited remarkably robust hydrophobic properties and low adhesion.…”

Recent Research on Preparation and Application of Smart Joule Heating Fabrics

“…However, the traditional single-carbon-precursor CVD graphene growth strategy commonly suffers from the severe thickness nonuniformity of the large-sized graphene film along the gas-flowing direction. As shown in Figure 4a, Liu et al [105] developed a complementary CVD graphene growth strategy based on the simultaneous introduction of mixed carbon precursors with high decomposition energy barriers (methane, CH 4 ) and low decomposition energy barriers (ethanol). The prepared large-scale and homogeneous GGFF exhibits a widely tunable temperature range (20-170 °C) at low working voltage (<10 V), ultrafast electrothermal response (29.7 °C s −1 at 9.8 V), and uniform large-area heating temperature (171.4 ± 3.6 °C in 20 cm × 15 cm).…”
