A novel method for producing microspheres with semipermeable polymer membranes
Abstract
A new and systematic approach for producing polymer microspheres has been demonstrated. The membrane of the microsphere is formed by immersing the polyanionic droplet into a collapsing annular sheet, which is made of another polycation polymer solution. This method minimizes the impact force during the time when the chemical reaction takes place, hence eliminating the shortcomings of the current encapsulation techniques. The results of this study show the feasibility of this method for mass production of microcapsules.
