Embodiment 1

[0034] 1. Preparation of polymer

[0035] A. Intrinsically conductive polymer fast ion conductor:

[0036]

[0037] Under nitrogen flow, the above components were charged in a flask, and polymerized at 55°C for 8 hours. The resulting finely particulate polymer was collected, washed thoroughly with 5000 parts of warm water and 2000 parts of methanol to remove the surfactant from the surface of the polymer, and the resulting product was lyophilized at °C.

[0038] B. Cationic granular polymer

[0039]

[0040] Under nitrogen flow, the above components were charged in a flask, and polymerized at 50° C. for 12 hours. The resulting granular polymer was collected and then thoroughly washed with 5000 parts of warm water and 2000 parts of methanol to remove the surfactant from the surface of the crosslinked granular polymer. The cross-linked granular polymer is dispersed in water to prepare a dispersion. Triethylamine was added to the dispersion, followed by stirring for 12 ...

[0045] 1. Preparation of fast ion conductor mosaic membrane

[0046] (1) Disperse polymer A in 250 parts of N,N-dimethylformamide and stir for 1 hour to obtain dispersion A, which is sealed for future use.

[0047] (2) Disperse polymer B in 350 parts of N,N-dimethylformamide and stir for 1 hour to obtain dispersion B, which is sealed for future use.

[0048] (3) Disperse polymer C in 350 parts of N,N-dimethylformamide and stir for 1 hour to obtain dispersion C, which is sealed for future use.

[0049] The resulting dispersion A was mixed with another dispersion consisting of the components of polymer B and polymer C to prepare a latex paint. The paint was applied to release paper coated with polypropylene resin using a knife coater. And make the polyester non-woven fabric closely contact with the coated surface, then dry with hot air, thus obtain the conductive fast ion conductor embedded ion exchange permeable membrane (also called fast ion conductor embedded membrane) of t...

Abstract

The invention provides a preparation method for a seawater desalting device with a fast ion conductor embedded film. According to the preparation method, intrinsic conductive polymers are polymerized into a fast ion conductor porous substrate material and the fast ion conductor porous substrate material and charged polymers are embedded and compounded, thereby forming a fast ion conductor embedded ion exchange permeable film capable of permeating and separating electrolyte. The film is a high-performance electrolyte separating film combined with driving power pressure difference, concentration difference and potential difference required by film separation. The invention also provides a manufacturing method for the seawater desalting device with the conductive fast ion conductor embedded ion exchange permeable film. The seawater desalting device is applied to the fields of reverse osmosis and electroosmosis, and no external power supply is required.
