|Title:||THE INVESTIGATION ON THE STRUCTURE, FABRICATION AND APPLICATIONS OF GRAPHENE||Authors:||DU DONGHE||Keywords:||graphene, graphene oxide, reduction, photoluminescence, electronic textile||Issue Date:||31-Jul-2017||Citation:||DU DONGHE (2017-07-31). THE INVESTIGATION ON THE STRUCTURE, FABRICATION AND APPLICATIONS OF GRAPHENE. ScholarBank@NUS Repository.||Abstract:||By investigating the structure of graphene oxide (GO), the long-wavelength photoluminescence of GO is evidenced to be originated from the excimer formation between GO basal plane and oxidative debris (ODs) attached on the GO sheets. The thermally unstable ODs would induce micro-explosion of GO upon heating. A novel method is developed to supress the explosion and achieve simultaneous thermal reduction and nitrogen doping of graphene oxide in air. The high quality N-doped graphene demonstrate excellent electrocatalytic property in oxygen reduction reaction. Furthermore, an electronic textile material is fabricated by coating chemically reduced GO on a piece of non-woven fabric (GNWF). GNWF can be applied as wearable sensors to detect physiological signals of human body. This research work deepens the understanding on the structure and property of graphene based materials and provides a cost-effective fabrication method for large scale production of graphene, and hence facilitates the commercialization of graphene.||URI:||http://scholarbank.nus.edu.sg/handle/10635/138193|
