Low-elastic modulus plasma polymer film

conference paper

English

The development of high-performance fiber-reinforced polymer composites is tightly bound with the design of composite interphases [1]. The interphase comprises the functional interlayer and a part of the polymer matrix affected by the presence of the coated fiber. The coated layer (interlayer) has to improve compatibility between the fiber and the matrix and to form strong but tough link between both the phases [2]. Plasma polymer films have been tested as functional interlayers since the 1980s [3]. However, thin films deposited by plasma-enhanced chemical vapor deposition (PE CVD) are too stiff with elastic modulus ranging from 60-160 GPa [4-7]. A stiff interlayer results in a strong but brittle composite material [8]. Therefore, preparation of a flexible and tough film with elastic modulus corresponding to that of polymer matrix (4 GPa) is required in current investigation.
