Microencapsulation and electrostatic processing method
Abstract
Method for preparing microcapsules comprising the steps of: formulating a primary solution; formulating a secondary solution; adding said primary solution to a first chamber; adding said secondary solution to a second position adjacent said first chamber chamber and separated from said first chamber by a porous barrier such that said second solution forms an interface with said primary solution at said porous barrier and moving said interface away from said porous barrier ; and allow microcapsule formation under quiescent low friction; and isolating said microcapsules by filtration through a porous barrier, wherein low friction conditions are defined as fluid friction forces under 10 N / m2 (100 dynes / cm2).
