Structurally well-defined bioactive films have been prepared in a single solventless step by atomizing precursor molecules into a non-equilibrium electrical discharge. By way of example, atomized spray plasma deposition is used to form poly(alkyl acrylate) arrays for phospholipid immobilization, and poly(N-acryloylsarcosine methyl ester) protein-resistant surfaces. Graphical Abstract
Pulsed plasmachemical deposited poly(maleic anhydride) nanolayers display high efficiency for the capture of toxic cadmium ions from aqueous solution (down to the low parts per billion range). Subsequent release of the isolated heavy metal species and host media regeneration is accomplished by rinsing in weak acid solution.
Photolithographic patterning of super-hydrophobic CF4 plasma fluorinated polybutadiene films is shown to provide sufficient surface energy contrast to facilitate spatially organized deposition of metal salts and polystyrene microspheres from a nebulized mist or solution.
Pulsed plasma polymerisation of butylacrylate monomer is found to lead to the deposition of polymeric films which are structurally very similar to conventional poly(butylacrylate). Carbon dioxide or oxygen plasma post treatment of these surfaces significantly improves their adhesive performance due to greater Lewis acid-base interactions at the interface.
