Hollow Grahene oxide and polyelectrolyte capsules were produced by using microfluidics system. In microfluidics system, inner oil phase was Quaternized poly(4-pyridine)-b-polystyrene (QP4VP-b-PS) or Polyethyleneimine in Chloroform, water middle phase was Graphene oxide and outer oil phase was Span 80 in Cyclohexane. After fabricating double emulsion droplet, fabricated hollow capsule by drying inner of that. And then assembled hollow capsule, fabricate thin films like graphene sponge. It expected oil absorption. Because Graphene oxide is amphiphilic. Also, fabricated multi layer-by-layer by using other polyelectrolytes. Generally, weak polyelectrolyte depends on pH. Hollow capsule expected pH responsibility because of weak polyelectrolyte. |
