Thin film composite hollow fiber membranes for osmotic power generation

摘要

Disclosed is a thin film composite hollow fiber that includes an outer support layer having a thickness of 10 to 1000 μm and a polyamide thin film layer having a thickness of 1 to 10000 nm; and has a transmembrane pressure resistance rate of higher than 15 bar and a pure water permeability rate of higher than 0.8 Lm−2h−1bar−1. Also disclosed are methods of preparing the above-described support and composite hollow fiber.
