In this paper, we describe the deposition of PEO‐like coatings using dielectric barrier discharges (DBDs) fed with aerosols of the TEGDME organic precursor in helium. By properly tuning plasma parameters such as aerosol/carrier flow ratio, frequency of the electric field applied and input power, the deposition process could be modulated to obtain coatings with variable PEO character, from 50% (cell adhesive) to 70% (nonfouling), which are interesting for surface modification of biomaterials and biomedical devices.

Atmospheric pressure plasmas are acquiring more interest in biomedical applications where synthetic biodegradable polymers modified to impart cells adhesion properties play a crucial role. This paper shows a new approach for the bio functionalization of such materials: inclusion of a biomolecule during the plasma deposition. A dielectric barrier discharge system was used for the coatings deposition, coupled with an atomizer for the lactic acid/ elastin aerosol feeding. ATR-FTIR, XPS, and UV-VIS were used to investigate the chemical composition of the coatings. By properly tuning plasma parameters, a good retention of the monomer chemical structure could be obtained in the coatings, as well as the inclusion of elastin in its structure.

Methyl methacrylate (MMA) is deposited on aluminum substrates using atmospheric dielectric barrier discharge plasma. The thermal properties of plasma deposited MMA (pdMMA) films of 0.5 to 1 μm thickness are evaluated as a function of plasma power and precursor mass feed. Thermogravimetric analysis indicates a low molecular weight fraction in all pdMMA films, which lowers their thermal stability. Differential scanning calorimetry (DSC) is used to quantify the glass transition (Tg) and residual reactivity of the pdMMA thin films. For all plasma conditions, the Tg remains inferior to conventional PMMA, and ranges from 20 °C in the monomer‐deficient domain to 56 °C in the energy‐deficient domain. A residual reactivity is measured in the first DSC heating of all pdMMA films, showing an exothermicity up to −160 J g−1.
