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.
一种用于在纳米厚度聚合物壳内封装液体颗粒的过程利用界面自由基交替共聚合过程。封装液体材料包括提供包括待封装的液体材料、疏水单体在非极性溶液中和亲水单体在极性溶液中的混合物。液体材料与极性溶液或非极性溶液中的任一种兼容。极性溶液和非极性溶液在彼此中不互溶。混合物经均质化形成乳液,然后由引发剂聚合,引发界面自由基交替共聚合过程。共聚合过程在最佳条件下仅受限于在疏水和亲水界面进行,从而形成液体材料周围的聚合物。
