部分聚合的膜在低温下表现出显著的机械转变，称为起皱转变。荧光和扫描电子显微镜以及原子力显微镜的轮廓测量表明，根据膜聚合程度的不同，存在三种程度的皱折。在低聚合时，膜经历级联起皱，形成特征指数ETA为3的折叠相；在中间聚合时，膜处于中间起皱阶段(类似于弹性片材的皱缩)，ETA约为2.5；而在高聚合时，膜突然“压缩”成起皱-粗糙相，ETA约为2。
Partially polymerized membranes display a striking mechanical transition at low temperature known as the wrinkling transition. Fluorescence and scanning electron microscopy as well as profile measurements using an atomic force microscope revealed the existence of three degrees of wrinkling depending on the degree of the membrane polymerization. At low polymerization the membrane undergoes a cascade of wrinkling to form a folded phase with a characteristic exponent eta equal to 3, at intermediate polymerization, the membrane is in an intermediate-wrinkled phase (similar to the crumpling of an elastic sheet) with eta approximately 2.5, while at high polymerization the membrane undergoes an abrupt "compaction" to the wrinkled-rough phase with eta approximately 2.
