Significance of Surface Modification by LCVD

The significance of LCVD is in the unique aspect of creating a new surface state that is bonded to the substrate material particularly polymeric material. The new surface state can be tailored to be surface dynamically stable. However, caution should be made that not all LCVD films fit in this category. Appropriately executed LCVD to lay down a type A plasma polymer layer creates surface dynamically stable surface state. In the domain, in which surface dynamic instability is a serious concern in the use of materials, a nanofilm by LCVD is quite effective in providing a surface dynamic stability, and other methods do not fare well in comparison to LCVD. 

The creation of new surface state, of which characteristics can be tailored, has a significant implication in controlling surface defects of materials, which act as the initiation sites of the fatigue process. In view of the fact that most materials fail due to fatigue, the retardation or possible prevention of the initiation of fatigue is a very important and unique advantage of LCVD.
