Amphiphilic block co-polymers are used to form large spherical vesicles. A sudden change in the osmotic pressure across the polymer membrane is used to induce the fission of the polymer vesicle. The membrane area to volume ratio, as expected, is observed to be a parameter suitable to describe the process and even mark the critical points along this transition. The effect of the length of the hydrophobic and hydrophilic chains on the fission process is analyzed. The effects of membrane lamellarity and initial polydispersity are thoroughly analyzed from the experimental data following mathematical models, and the phenomenon of fission in these polymer vesicles is understood via measurements characterizing the membrane, i.e., area stretch modulus.

大分子囊泡中渗透诱导的膜裂变：多层性和两亲嵌段长度的影响

两亲性嵌段共聚物用于形成大的球形囊泡。跨过聚合物膜的渗透压的突然变化用于引起聚合物囊泡的裂变。如所预期的，膜面积与体积之比被认为是适合于描述该过程甚至在该转变过程中标记临界点的参数。分析了疏水链和亲水链的长度对裂变过程的影响。根据数学模型从实验数据中彻底分析了膜层状性和初始多分散性的影响，并且通过表征膜的测量（即面积拉伸模量）了解了这些聚合物囊泡中的裂变现象。
