Patent number: 8029709Abstract: A process for the encapsulation of liquid particles within nanometer thick polymer shells utilizes an interfacial free radical alternating copolymerization process. Encapsulating a liquid material includes providing a mixture comprising the liquid material to be encapsulated, a hydrophobic monomer in a non-polar solution and a hydrophilic monomer in a polar solution. The liquid material is compatible in either the polar solution or the non-polar solution. The polar solution and the non-polar solution are not miscible in each other. The mixture is homogenized to form an emulsion, and then polymerized by an initiator which initiates an interfacial free radical alternating copolymerization process. The copolymerization process is optimally constrained to proceed only at the hydrophobic and hydrophilic interface thus forming a polymer around the liquid material.Type: GrantFiled: October 31, 2005Date of Patent: October 4, 2011Assignee: The University of CincinnatiInventors: Dan Wu, Charles Scott, Carlos Co, Chia-Chi Ho
