Abstract

Abstract: A bottom-up approach for producing poly(vinyl alcohol) (PVA)/graphene oxide (GO) nanocomposites using a spray-assisted layer-by-layer (LbL) method is presented. Simple and versatile, the process allows to build up uniform multi-layered nanocomposite films with good morphological control of each layer. A total of 150 bilayers were deposited to create a transparent film with improved mechanical properties at a loading of 5.4 wt% GO. The Young's modulus and tensile strength of these films nearly doubled as a result of the high level of structural organization of the nanocomposite incorporating the two-dimensional (2D) nanofiller, in combination with good interfacial interactions resulting from hydrogen bonding between PVA and the GO sheets.
