  • Publication number: 20190096592
    Abstract: A method of manufacturing a composite material is provided. First, graphene oxide and activated carbon are provided individually. Graphene oxide and activated carbon are added into an alcohol to form a mixture. Then, the mixture is heated by microwave in a single step, so that graphene oxide is chemically reduced to form graphene at the active sites of the surface of the activated carbon uniformly, thereby forming a composite material. The embodied composite material is suitable for being the electrodes of the capacitive deionization (CDI) and supercapacitor application.

  • Patent number: 10016725
    Abstract: A forward osmosis process is provided, which includes separating a feed part and a draw solution part by a semi-permeable film. An ionic liquid is introduced into the draw solution part, and brine is introduced into the feed part. The brine has an osmotic pressure lower than that of the ionic liquid, so that pure water of the brine permeates through the semi-permeable film, enters the draw solution part, and mixes with the ionic liquid to form a draw solution. The draw solution was obtained out of the draw solution part to be left to stand at room temperature, so that the draw solution separated into a water layer and an ionic liquid layer.
