NOVEL METHOD FOR PREPARING PARTICLES WHEREOF AT LEAST THE PERIPHERAL SURFACE IS POLYMERIC, USING A MEMBRANE REACTOR

摘要

The invention concerns a method for preparing particles, and in particular nanoparticles, whereof at least the peripheral part is polymeric, from a first liquid phase A and a second liquid phase B at least partly miscible, the second phase B containing a precursor of the polymeric part of the particle, said precursor being soluble in the phase B and at least partly insoluble in the phase A. The invention is characterized in that it uses a membrane reactor comprising a porous membrane, wherein the first phase A circulates tangentially to the membrane, and the second phase B passes through the pores of the membrane before mixing with the first phase A, to form the nanoparticles.
