Graphene-based de-icing composites are of great interest due to incredible thermal, electrical and mechanical properties of graphene. Moreover, current technologies possess a number of challenges such as expensive, high power consumption, limited life time and adding extra weight to the composites. Here, we report a scalable process of making highly conductive graphene-based glass fibre rovings for de-icing applications. We also use a scalable process of making graphene-based conductive ink by microfluidic exfoliation technique. The glass fibre roving is then coated with graphene-based conductive inks using a dip-dry-cure technique which could potentially be scaled up into an industrial manufacturing unit. The graphene-coated glass roving demonstrates lower electrical resistances (∼1.7 Ω cm) and can heat up rapidly to a required temperature. We integrate these graphene-coated glass rovings into a vacuum-infused epoxy-glass fabric composite and also demonstrate the potential use of as prepared graphene-based composites for de-icing applications.
基于石墨烯的除冰复合材料因其具有令人难以置信的热、电和机械性能而备受关注。此外，当前技术存在诸多挑战，如成本高昂、功耗高、使用寿命有限以及会增加复合材料的额外重量。在此，我们报告了一种用于制造用于除冰应用的高导电性基于石墨烯的玻璃纤维粗纱的可扩展工艺。我们还通过微流体剥离技术采用了一种制造基于石墨烯的导电油墨的可扩展工艺。然后使用浸涂 - 干燥 - 固化技术用基于石墨烯的导电油墨涂覆玻璃纤维粗纱，该技术有可能扩大规模成为工业制造单元。涂覆石墨烯的玻璃粗纱显示出较低的电阻（约1.7Ω·cm），并且能够迅速升温至所需温度。我们将这些涂覆石墨烯的玻璃粗纱集成到真空灌注的环氧 - 玻璃织物复合材料中，并展示了所制备的基于石墨烯的复合材料在除冰应用中的潜在用途。
