    With the increasing demand for lithium resources, it is of great significance to develop a new technology for the selective recovery of lithium from complex systems. In the present work, antifouling lithium-imprinted hybrid membranes (LIHMs) were fabricated through a hydrolysis polymerization method using a PVDF/GO hybrid membrane as a basement membrane, and polydopamine as an adhesion layer to anchor imprinted sites. The antifouling experiments demonstrated that LIHMs had the underwater oil contact angle of 152 +/- 0.8 degrees. Furthermore, the adsorption isotherms, permeation and adsorption kinetics of the LIHMs were researched in detail. The results displayed that LIHMs showed a distinctive adsorption capacity (27.10 mg g(-1)) and permselectivity (beta(K/Li) = 5.3780, beta(Ca/Li) = 21.9402, beta(Mg/Li) = 15.5620) for lithium. Also, the regeneration experiments confirmed the good durability of LIHMs, favoring long-term use. Therefore, the LIHMs provided a powerful tool for the effective separation and recovery of lithium in practical applications.
