Abstract
Proposed is to provide a size-varying bubble complex and a method of preparing the same. More specifically, the size-varying bubble complex and the method of preparing the same are proposed, wherein the bubble complex is capable of being repeatedly varied in size by changing phases of perfluorocarbon by external stimuli, by including a shell that encapsulates a core made of the perfluorocarbon and protects the core by expanding and contracting together when the core expands and contracts.
