  • Patent number: 8696952
    Abstract: The present invention provides a method and apparatus for producing polymeric particles with pre-designed size, shape, morphology and composition, and more particularly the present invention uses a microfluidic polymerization reactor for producing same. The present invention disclosed herein provides a process for producing polymer particles with pre-selected shapes. The method includes injecting a first fluid comprising a polymerizable constituent with a controlled flow rate into a microfluidic channel and injecting a second fluid with a controlled flow rate into the microfluidic channel in which the second fluid mixes with the first fluid, the second fluid being immiscible with the first fluid so that the first fluid forms into droplets in the microfluidic channel. The microfluidic channel has pre-selected dimensions to give droplets of pre-selected size, morphology and shape.
