Graphene Oxide Containing Composite Hydrogel Fabricated by Freeze/Thaw Method

摘要

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.
