AB  - The effect of graphene oxide (GO) or reduced GO (rGO) on the structure and 
      properties of polyelectrolyte-complexed chitosan/alginate bionanocomposites is 
      highly dependent on plasticiser type (glycerol or 1-ethyl-3-methylimidazolium 
      acetate ([C(2)mim][OAc])) due to the competing interactions between the 
      components. For the glycerol-plasticised chitosan/alginate matrix, inclusion of 
      GO/rGO enhanced the chitosan crystallinity and increased matrix ductility. While 
      the chitosan/alginate matrix plasticised by [C(2)mim][OAc] showed dramatically 
      weakened interactions between the two biopolymers, GO was highly effective at 
      counteracting the effect of [C(2)mim][OAc] by interacting with the biopolymers 
      and the ionic liquid ions, resulting in enhanced mechanical properties and 
      decreased surface hydrophilicity. Compared with GO, rGO was much less effective 
      at promoting chitosan-alginate interactions and even resulted in higher surface 
      hydrophilicity. However, irrespective of the plasticiser type, inclusion of rGO 
      resulted in reduced crystallinity by restricting the interactions between 
      [C(2)mim][OAc] and the biopolymers, and higher ionic conductivity.
