| titleOfInvention | A kind of forward osmosis membrane with mica sheet as intermediate layer and preparation method thereof |
| abstract | The invention relates to a forward osmosis membrane with a mica sheet as an intermediate layer and a preparation method thereof. The forward osmosis membrane comprises a base membrane and a polyamide membrane layer located on the base membrane, and between the base membrane and the polyamide membrane layer, two Dimensional nano-mica flakes in the middle layer. In the present invention, mica sheet is applied to the forward osmosis membrane for the first time, and the mica sheet is selected as the intermediate layer, which is located between the base film and the polyamide layer. The two-dimensional nano mica sheet has good hydrophilicity, good layered nanostructure and strong The electronegativity can shorten the water molecule transfer path, water flux and salt interception performance can be greatly improved. A new type of TFC film was prepared by using the base film containing mica sheet as the substrate, through the interfacial polymerization reaction between polyamine and polyacyl chloride, so that the two-dimensional mica sheet was located between the base film and the polyamide layer. Compared with the unmodified TFC membrane, the mica shortens the water molecule transfer path, reduces the water quality transfer resistance, and promotes the rapid transport of water molecules. |
