Different plasma processes were investigated to obtain coatings characterized by N- and O- functional groups at their surface. From the literature, big efforts are evident devoted to designing new surfaces with chemical composition and chemical–physical properties tightly controlled. This paper demonstrates how it is possible to obtain coatings with acid and basic properties at different extent, by simply adjusting the acrylic acid/allylamine chemical composition of the gas feed in a plasma deposition process. The deposited films exhibit tuneable acid–base properties, very attractive to manufacture sensors, and biomaterials, and for applications in tissue engineering field.
