Abstract: The present invention relates to a reverse osmosis membrane and a method of preparing the same, and more particularly to a high durability reverse osmosis membrane which is excellent in interlayer bonding in a separation membrane while maintaining an equal flow rate as compared with a conventional reverse osmosis membrane to minimize a reduction in durability in the membrane upon backwashing to enhance a cleaning effect, prolong the life of a highpressure membrane, maximize the amount of accumulated treated water, and reduce maintenance costs, and a method of preparing the same.
