“…For instance, in the biomedical field, the chemistry of the surface, as quantified by density of functional groups, is essential for controlling protein bonding or the attachment and growth of cells 12, 67, 68. Additionally, the dynamic response of stimuli‐responsive materials, that is to say, materials that change their properties following an external stimulus, also depends strongly on the density of functional groups on the surface 69, 70, 71…”

Well-adhered, conformal, thin (<100 nm) coatings can easily be obtained by chemical vapor deposition (CVD) for a variety of technological applications. Room temperature modification with functional polymers can be achieved on virtually any substrate: organic, inorganic, rigid, flexible, planar, three-dimensional, dense, or porous. In CVD polymerization, the monomer(s) are delivered to the surface through the vapor phase and then undergo simultaneous polymerization and thin film formation. By eliminating the need to dissolve macromolecules, CVD enables insoluble polymers to be coated and prevents solvent damage to the substrate. CVD film growth proceeds from the substrate up, allowing for interfacial engineering, real-time monitoring, and thickness control. Initiated-CVD shows successful results in terms of rationally designed micro- and nanoengineered materials to control molecular interactions at material surfaces. The success of oxidative-CVD is mainly demonstrated for the deposition of organic conducting and semiconducting polymers.

“…The high degree of conformal coverage achievable via iCVD can be utilized to fabricate free‐standing nanotubes using a membrane as a template. A film of poly(ethylene glycol diacrylate) (PEGDA) was deposited on polycarbonate membranes that were later dissolved in chloroform 29, 34. By altering the pore geometry of the membrane, various kinds of nanotubes were obtained.…”

“…Since conformal surface coatings can make the surface energy of complex substrates uniform, iCVD polymer coatings can be used to study the effects of surface topography in isolation. Recently, a directional surface structure was fabricated using a conventional photolithography process and tilted‐angle deposition of a gold film 34. By conformally coating the structure using iCVD PEGDA, the surface structure effect could be successfully decoupled from the effect of surface chemistry.…”

This review will focus on the controlled release of pharmaceuticals and other organic molecules utilizing polymeric nanolayers grown by initiated chemical vapor deposited (iCVD). The iCVD layers are able conform to the geometry of the underlying substrate, facilitating release from one- and two-dimensional nanostructures with high surface area. The reactors for iCVD film growth can be customized for specific substrate geometries and scaled to large overall dimensions. The absence of surface tension in vapor deposition processes allows the synthesis of pinhole-free layers, even for iCVD layers <10 nm thick. Such ultrathin layers also provide rapid transport of the drug across the polymeric layer. The mild conditions of the iCVD process avoid damage to the drug which is being encapsulated. Smart release is enabled by iCVD hydrogels which are responsive to pH, temperature, or light. Biodegradable iCVD layers have also be demonstrated for drug release.
