Abstract
  • NOVELTY - Method for preparing a film, preferably multilayer barrier film by plasma-enhanced chemical deposition is claimed. The film has nanometric thickness for releasing target substances into a surrounding medium containing liquids, from a substrate containing the substance as micro/nanoparticles, or from a layer deposited on the substrate containing the as micro/nanoparticles, or from a layer of the substance deposited on the substrate, or from a substrate containing substance that is released possibly in the form of particles. USE - The method is useful for preparing film, preferably multilayer barrier film on structures for releasing to-be-released substance chosen from metals, compounds having antibacterial properties, and biologically active molecules (preferably drugs, hormones, vegetable extracts, peptides, lipids, protides and glucides). The structures are chosen from medical-surgical devices, common handworks, and scaffolds. The medical-surgical devices are syringes, prosthesis, catheters, contact lenses, cardiac valves, intraocular lenses and hemodialysis filters. The common handworks are hemodialysis filters, filters for air conditioning systems, toothbrushes, long lasting razor blades, fluid circulation tubes, operating room sterile towels and tissues (all claimed). ADVANTAGE - The film releases target substances in controlled, uniform and long lasting way. DETAILED DESCRIPTION - Method for preparing a film, preferably multilayer barrier film by plasma-enhanced chemical deposition is claimed. The film has nanometric thickness for releasing target substances into a surrounding medium containing liquids, from a substrate containing the to-be-released substance as micro/nanoparticles, or from a layer deposited on the substrate containing the to-be-released substance as micro/nanoparticles, or from a layer of the to-be-released substance deposited on the substrate, or from a substrate containing to-be-released substance that is released possibly in the form of particles. The layer with the to-be-released substance is obtained by performing plasma-enhanced chemical deposition on organic or inorganic structure having polyethylene oxide (PEO), polyethylene glycol (PEG), or PEO-like polymers which constitute variable percentage of ethylene oxide units. The barrier film is obtained by adjusting degree of crosslinking and thickness of the film by plasma-enhanced chemical deposition process, and adjusting release of the active substance with respect to specific needs.
