Accelerating the design of molecularly imprinted nanocomposite membranes modified by Au@polyaniline for selective enrichment and separation of ibuprofen

•An Au@ polyaniline nanocomposite structure was obtained.•ATRP was used for synthesis the ibuprofen-based imprinted nanocomposite membrane.•The as-prepared MINcMs showed high adsorption capacity toward ibuprofen.•The Au@polyaniline special structure endowed the as-prepared membrane with excellent selectivity.
