Fibre Surface/Interfacial Engineering on Wearable Electronics

Surface/interfacial engineering is an essential technique to explore the fibre materials properties and fulfil new functionalities. An extensive scope of current physical and chemical treating methods is reviewed here, alongside a variety of real-world applications. Moreover, we also introduce a new surface/interface engineering approach; self-assembly via π–π stacking, which has great potential for the surface modification of fibre materials due to its non-destructive working principle. This review also introduces a new fibre family member, MOF fibres, which show promising candidacy for fibre based wearable electronics. This review advances the understanding of surface/interfacial engineering techniques on fibre materials and will be expected to guide the rational design of future fibre based wearable electronics.
