An amphiphilic monomer dihexadecyldimethylammonium 4-vinylbenzoate was synthesized and vesicles were prepared by sonic dispersal of the surfactant. Using AIBN as an initiator vesicle polymerization was carried out. The polymerized vesicles synthesized in this study are called "polymer-encased vesicles", because those vesicles have surfactant bilayers which are encased within two concentric polymerized monolayers. And polymerized vesicles were prepared with crosslinker and the surfactant bilayer was extracted, and the formation of thin polymer spheres (ghost vesicles) were observed. The polymer-encased vesicles and the ghost vesicles were characterized by the electron micrographs.

Dihexadecyldimethylammonium 4-vinylbenzoate를 합성한 다음 이것으로부터 sonication을 이용하여 vesicle 용액을 형성시켰다. 이 용액으로부터 AIBN을 개시제로 고분자화된 vesicle을 합성하였다. 여기서 얻어진 고분자화된 vesicle은 고분자 단분자 층으로 이루어진 막에 의해서 안정화된 구조를 하고있어 polymer-encased vesicle 이라고 명하였다. 또한 여기에 crosslinker를 첨가해서 고분자화 반응을 하고 반응이 끝난 후 surfactant 부분을 추출해 냄으로써 고분자 단분자 층으로 이루어진 둥근 모양의 형체물을 형성시켰다. 이것을 ghost vesicle 이라고 명하였다. Polymer-encased vesicle 과 ghost vesicle 은 각각 전자 현미경 사진으로 확인하였다.
