Thermo-responsive and magnetic molecularly imprinted Fe3O4@carbon nanospheres for selective adsorption and controlled release of 2,4,5-trichlorophenol

Thermal-responsive and magnetic molecularly imprinted polymers (TMMIPs) based on Fe 3 O 4 @carbon (Fe 3 O 4 @C) were prepared by free radical polymerization and applied to selective adsorption and controlled release of 2,4,5-trichlorophenol (2,4,5-TCP) from aqueous solution. TMMIPs were composed of multilayer structure, and exhibited magnetic sensitivity, magnetic stability and thermal stability (especially below the. The reversible transform of mean diameter resulted from the change of testing temperature, indicating the thermo-responsive properties of TMMIPs. Selective adsorption and controlled release of 2,4,5-TCP were also investigated at 25   °C and higher temperature (such as 45   °C and 60   °C), respectively.
