Vinyl-based interlayers synthesized by variable pulsed plasma for polymer composites

Abstract

The low-pressure pulsed plasma is a crucial tool for the construction of materials in the form of coatings with variable properties. The pulsed mode is characterized by many parameters such as pulse on-time, off-time, pulse period, pulse frequency, duty cycle, and using the total power, the average power during the pulse can be introduced as the effective power. Based on a pulse period ranging from 2 to 100 ms and a total power of 10–500 W, it is demonstrated that the effective power is the key parameter responsible for the properties of the synthesized coatings independent of the total power. When an organosilicon precursor with a vinyl functional group, this parameter allows the chemical and physical properties of vinyl-based coatings to be controlled over a wide range, allowing to optimize their properties as functional interlayers in polymer composites to control their performance.
