low surface free energy 低表面自由能
One is to create a rough structure on a hydrophobic surface, and the other is to modify a rough surface by materials with low surface free energy.
一般情况下，超疏水表面可以通过两种方法来制备：在疏水性表面构建粗糙结构或者在粗糙表面修饰低表面能物质。
It has been known that UV-curing coatings is difficult to adhere onto the plastic substrates that show very low surface free energy.
紫外光固化涂料在表面自由能低的塑料底材上附着极为困难。
If the silane has no polar group, the surface free energy is low.
反之若硅烷中不含有极性基，则处理后玻纤的表面能较低。
