Elastic bubble complex and method of preparing the same

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.

What is claimed is: 
     
         1 . A preparing method of a bubble complex, the method comprising:
 a first injection step of injecting perfluorocarbon into an alginate liquid solution;   a first obtaining step of obtaining perfluorocarbon whose outer surface is encapsulated with the alginate liquid solution by absorbing perfluorocarbon injected into the alginate liquid solution;   a second injection step of injecting perfluorocarbon whose outer surface is encapsulated with the alginate liquid solution into corn syrup;   a second obtaining step of obtaining perfluorocarbon coated in turn with the alginate liquid solution and corn syrup by absorbing perfluorocarbon injected into the corn syrup;   a coating step of providing a PFC-coating layer complex, which has the core made of perfluorocarbon and a coating layer encapsulating the core and made of alginate, the PFC-coating layer complex provided through a reaction that occurs as the alginate liquid solution is brought into contact with the calcium chloride solution as the corn syrup gradually dissolves by injecting the perfluorocarbon coated in turn with the alginate liquid solution and corn syrup into calcium chloride solution to react to each other;   a third obtaining step of obtaining the PFC-coating layer complex whose outer surface is encapsulated with the elastic material liquid solution by absorbing the PFC-coating layer complex injected into the elastic material liquid solution;   a fourth injection step of injecting the PFC-coating layer complex whose outer surface is encapsulated with the elastic material liquid solution; and   a curing step of providing the bubble complex, provided with the core made of perfluorocarbon and a coating layer, which encapsulates the core and is made of the alginate, and a shell   which encapsulates the coating layer and is made of the elastic material, by rotating a container containing the supporting liquid solution to apply centrifugal force to the supporting liquid solution and simultaneously naturally curing the supporting liquid solution.   
     
     
         2 . The method of  claim 1 , wherein the PDMS liquid solution is used as the elastic material liquid solution, and
 epoxy resin is used as the supporting liquid solution.
