Abstract

Next to surface modification and activation of polymers [1,2], a plasma can also be used to deposit thin films by
means of a so-called plasma polymerization [3]. In this work, Methyl methacrylate (MMA) is chosen as a model
precursor to be polymerized in an atmospheric dielectric barrier discharge reactor operating in dynamic mode.
The plasma input power and frequency are treated as variable external plasma parameters and their effect on the
thermal properties (such as the glass transition temperature) of the synthesized films is studied by Differential
Scanning Calorimetry (see fig. 1). In all cases, the observation is made that the plasma coatings possess a
residual reactivity. The magnitude of this residual reactivity varies with plasma power. Thermal stability of the
plasma films is studied by Thermal Gravimetric Analysis and information on the chemical structure of the
coatings is obtained through Fourier Transform Infrared Spectroscopy.

Using MMA as model precursor enables the comparison of plasma polymerized films to conventionally
polymerized poly(methyl methacrylate).
