Embodiment 1
[0035] 2 groups of supramolecular reinforcement reinforced liquid crystal supramolecular / polyethersulfone hollow fiber membrane:
[0036] 1. Prepare polyethersulfone casting solution and let stand for defoaming;
[0037] 2. Combine hydroxyl carbon nanotubes, liquid crystal supramolecules, polyethersulfone, etc. with high temperature and high pressure sputtering solution;
[0038] 3. Set the sputter spinning conditions, including: the sputter pressure is 1 MPa, the sputter speed is 5m / s, the sputter spinning equipment is turned on, and the supramolecular yarn is spun by air spinning technology;
[0039] 4. Turn on the hollow fiber spinning machine, and under a certain temperature and pressure, make the casting solution pass through the spinneret, enter the coagulation bath with the supramolecular yarn at the same time, and undergo phase transformation to form a film. The supramolecule wraps the polyethersulfone, and at the same time wraps the hydroxyl carbon nanotube and embed...
