Deposition of polymeric thin films from propane-butane in atmospheric pressure discharge

In our experimental work we prepared thin films via plasma polymerisation and characterized them. These films were prepared on a glass substrate in the dielectric barrier discharge (BDB). The wettability of the deposited layers was determined by measuring of the contact angle and the free surface energy of the layers using the SEE system apparatus. The atomic composition and the surface morphology of the thin layers was characterized by scanning electron microscopy (SEM). Performed biological tests of biocompatibility and antibacterial properties provided information on the viability of the cells on the layers and their antibacterial effects.
