Abstract
Global warming, contributing to the worsening climate crisis, has led to more frequent heavy snowfall and rainfall. This causes corrosion, mold, and structural damage to roofs, which shortens the roofs' lifespan and potentially creates safety hazards. Addressing these challenges, we propose an approach to develop a multifunctional roof crucial for proactive adaptation to extreme weather. In this article, we present hydrophobic laser-induced graphene (LIG) onto wood in a single-step process using femtosecond-laser-direct-writing (FsLDW) technology in ambient air without additional chemical treatment. This hydrophobic LIG, showcasing a high electrical conductivity of 10.0 Ω·sq⁻1 and a high contact angle of 148.8°, seamlessly integrates onto roofs, creating cost-effective, fast, eco-friendly, and smart roofing solutions. The hydrophobic surface of these LIG electrodes incorporates a heating function of LIG showcasing their versatility in providing waterproofing, drying wood, and facilitating de-icing functions. This eco-friendly invention, reliant solely on laser patterning on wood, not only extends roof lifespan but also relieves concerns about electronic waste and recycling, promising the integration of green, smart, and sustainable roofing solutions.
全球变暖加剧了气候危机,导致降雪和降雨更加频繁。这导致屋顶腐蚀、发霉和结构损坏,从而缩短了屋顶的使用寿命,并可能造成安全隐患。为了应对这些挑战,我们提出了一种开发多功能屋顶的方法,这对主动适应极端天气至关重要。在本文中,我们利用飞秒激光直写(FsLDW)技术,在环境空气中通过一步法将疏水性激光诱导石墨烯(LIG)涂覆到木材上,无需额外的化学处理。这种疏水性石墨烯导电率高达 10.0 Ω-sq-1,接触角高达 148.8°,可无缝集成到屋顶上,创造出经济、快速、环保的智能屋顶解决方案。这些 LIG 电极的疏水表面结合了 LIG 的加热功能,在防水、干燥木材和促进除冰功能方面展示了其多功能性。这项完全依靠激光在木材上绘制图案的环保发明,不仅延长了屋顶的使用寿命,还解除了人们对电子废物和回收利用的担忧,有望整合出绿色、智能和可持续的屋顶解决方案。
期刊介绍:
The journal Carbon is an international multidisciplinary forum for communicating scientific advances in the field of carbon materials. It reports new findings related to the formation, structure, properties, behaviors, and technological applications of carbons. Carbons are a broad class of ordered or disordered solid phases composed primarily of elemental carbon, including but not limited to carbon black, carbon fibers and filaments, carbon nanotubes, diamond and diamond-like carbon, fullerenes, glassy carbon, graphite, graphene, graphene-oxide, porous carbons, pyrolytic carbon, and other sp2 and non-sp2 hybridized carbon systems. Carbon is the companion title to the open access journal Carbon Trends. Relevant application areas for carbon materials include biology and medicine, catalysis, electronic, optoelectronic, spintronic, high-frequency, and photonic devices, energy storage and conversion systems, environmental applications and water treatment, smart materials and systems, and structural and thermal applications.
