At present, organic membrane materials are commonly used in industry for filtration and separation treatment from microfiltration, ultrafiltration and nanofiltration to reverse osmosis, and although the organic membrane materials have good application in water treatment, the commonly used organic membrane components are basically filtered and separated at normal temperature and cannot be used at high temperature for a long time.
