Has residual solvent an impact on the dynamics of PMMA ultra thin films?

Polymeric films thinner than a 100 nm exhibits a variation of the glass transition temperature of a few tens of degrees and can brake up into discrete islands when heated near...厚度小于100 nm的聚合物薄膜，其玻璃化转变温度会出现数十摄氏度的波动；当加热至接近某一温度时，该薄膜可裂解为离散的岛状结构。
