How does Tg reduction affect the chain mobility in confined PS films?
It is well known that glass transition temperature (Tg) of supported polystyrene (PS) thin films decreases with decreasing film thickness. More recently fluorescence measurements using pyrene doped PS films demonstrated that Tg of a&nb...

表面等离子体改性增容PP/PS合金研究
关键字：PP/PS合金
等离子体可分为高温等离子体和低温等离子体[1]，低温等离子体又称为非平衡等离子体。由辉光放电和无声放电（介质阻挡放电）可得到低温等离子体，用低温等离子体使惰性聚合物表面活化能够形成多种化学反应。当使用非聚合反应气体，如氩气和氦气处理聚合物表面时，能够产生活性集团与空气中氧和水反应，进而能形成接枝聚合单体，如丙烯酸，得到亲水的表面或交联层。聚合物表面的等离子体修饰或改性十分广泛。因此，有大量的研究和应...
