PolyU Science Research Impact 2022 EP08 – Graphene Coating Solution for Wearable Electronics

Abstract

可穿戴電子設備是指佩戴在使用者身上，並能提供智能輔助的微型電子裝置，例如智能手錶、智能眼鏡、珠寶或服裝。這些設備均需金屬導電，然而金屬在遭受氧化和腐蝕後會失效，因此要維持良好的導電性變得非常有挑戰性。 理大理學院柴揚教授注專可導電纖維和織物的研究。他所研發的嶄新塗層技術，透過使用高度不滲透的石墨烯作為保護塗層，防止導電纖維因洗滌和人體汗液而腐蝕。這項技術可以有效減慢金屬導電纖維腐蝕的速度約66倍。 Wearable electronics are microelectronic devices worn on the user's body to provide intelligent assistance, and include smartwatches, eyeglasses, jewellery and clothing. These devices require the use of metals to conduct electricity. However, metal conductivity is susceptible to oxidation and corrosion, which makes their maintenance challenging. PolyU Science Researcher Prof. Chai Yang focuses on conductive fibre and fabric research. His innovative coating technique using impermeable graphene as the protection layer for wearable fibre and fabric can prevent corrosion caused through washing and human perspiration. This graphene protection layer can reduce the corrosion rate of conductive fibre by approximately 66 times.
