摘要
A mixture of vinyl monomer, a natural polyelectrolyte-hyaluronic acid-and crosslinker was polymerized and crosslinked to entrap the natural polymer into the synthetic gel. The controlled release of the model drug from the obtained gel was studied under the on-off switching of electric field. It was proved that electric-responsive drug releases were possible using hyaluronic acid entrapping gel and the electro-responsiveness was greatly affected by various factors such as degree of swelling, crosslinking density, kind and composition of vinyl monomer and crosslinkers.
