The reason for the undeserved complications of polyacrylamide hydrogel injection for augmentation mammaplasty is unstandard operation.

The apparent degree of network chains for the different swollen extent of the same unswollen hydrogel sample increased linearly with the increase of swelling ratio, however, the apparent modulus did not decrease monotonously with the increase of swelling ratio. Furthermore, the dependence of apparent degree of network chains on swelling ratio had nothing to do with the swelling agent. The above results reflected the changes of entanglement and the contribution of entanglement under different swelling ratio, and the results could be explained with the theory of Flory-Erman's constrained junction model and LangleyGraessley relation.

发现同一水凝胶样品的不同溶胀程度试样经应力应变测试得出的表观网链密度随体积溶胀率的增加而线性增加，等效模量并不随溶胀程度的增加而单调减小，而表观网链密度的溶胀程度依赖性与所选用的溶胀剂无关，该结果反映了不同溶胀程度下缠结的变化及缠结对弹性的不同贡献，并可由Flory-Erman的constrained junction模型及Langley-Graessley公式得到解释。

MATERIALS: Ethylene glycol methacrylate compound with methyl methacrylate was mixed with NaCl solution to obtain porous hydrogel orbital implant; polyurethane membrane was established using electrospinning method. A volume fraction of 75% ethanol was used to make homologous sclera wrappage.
