Abstract:

The anodic alumina oxide(AAO) porous membrane was treated with low-temperature air plasma to obtain superhydrophilic nanochannels. An oil-soluble ferrofluid was introduced on the AAO membrane, and an intelligent and controllable microreactor was constructed by adjusting the direction and strength of the external magnetic field. The intelligent microreactor has the characteristics of multilevel gating, high current-gating ratio, and long-term cycle stability. It was used in homogeneous and heterogeneous reactions and characterized by fluorescence spectrophotometer and scanning electron microscope. The results showed that the reaction products have different yields and structures under different gated states, and have good application prospects in the controllable reaction of microreactors.

Key words: Superhydrophilic nanochannel, Microreactor, Multilevel gating, Ferrofluid
