Spraying Method

ABSTRACTA bottom-up approach for poly(vinyl alcohol) (PVA) - graphene oxide (GO) nanocomposites using a spraying method is presented. Very simple and versatile, spraying allows to build-up uniform layered composite films with good control on the structure of each layer. 150 bi-layers were deposited to create a transparent film with improved mechanical properties at a loading of 5.4 wt.% GO. The Young’s modulus and strength of these films doubled or nearly doubled which is believed to be due to a synergic effect as a result of the nanoscale organization of the composite by the 2D nanofiller, and hydrogen bonding between the PVA and the GO.

Inorganic Fillers

Graphene oxide (GO) was used as inorganic fillers to enhance the mechanic properties of graphene oxide/poly(vinyl alcohol) composite hydrogels that were prepared by freeze/thaw method. The structure and properties of the composite hydrogels were characterized. Since GO was well dispersed in polymer matrix, the composite hydrogels showed an outstanding mechanical improvement. Significant increase in Young's modulus and compressive strength was achieved, indicating a good load transfer between fillers and matrix.
