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. The ionic liquid includes
Abstract:
A method of fabricating a sheet or a fabric with crystalline TiO2 nano-particles includes providing a polymer material as a support, and then synthesizing the crystalline TiO2 nano-particles with immobilizing them on a surface of the support, followed by forming the fabric or the sheet. The fabric is a textile or a nonwoven fabric. A type of the support is a fiber or a sheet type. The synthesizing of the crystalline TiO2 nano-particles is performed by occurring a sol-gel reaction under a microwave irradiation, wherein a TiO2 precursor, water, an alcohol, and an ionic liquid applied in the sol-gel reaction during the synthesizing.
Abstract:
A method of manufacturing a porous fluorine-containing polymer membrane is provided, which includes mixing a fluorine-containing polymer, a pore creating agent, and a solvent to form a mixture; forming a membrane of the mixture, and removing the pore creating agent and the solvent in the membrane to form the porous fluorine-containing polymer film. The pore creating agent has a chemical formula of wherein R1 is a C1-8 alkyl group, a C2-8 alkenyl group, a C2-8 alkynyl group, or a C6-12 aromatic group, and A⊖ is hydrogen sulfite ion, dihydrogen phosphate ion, nitrate ion, halogen ion, or a combination thereof. The solvent has a chemical formula of
