“…A similar positive result in a platelet adhesion study has also been reported by Kiaei and Hoffman, for their plasma polymerized HMDSO on PET coverslip . Encouraging results for siloxane‐coated polymeric substrates have also been reported for their studies with ex vivo animal models implanted with plasma polymerized devices produced from hexamethylcyclotrisiloxane and HMDSO …”

This review focuses on low-pressure plasma modification methods to produce hydrophobic coatings and surface modifications on biomaterials. Plasma-deposited fluoropolymer, siloxane, and diamond-like carbon (DLC) coatings are reviewed in terms of process developments, monomers used, stability and aging properties, and their behavior in adsorption of proteins, cell attachment, and bacterial adhesion. These hydrophobic coatings are stable with correct selection of monomers and process conditions, but the plasma polymerized siloxane and fluorocarbons have been mainly applied in biochip and test kits rather than in blood-contact applications. Similarly, the surface characteristics and interfacial bonding of DLC coatings play a crucial role in their successful implementation.

“…

of 3D Li + batteries, desired for their high free energy density within a small areal footprint, [ 6,7 ] is limited by the lack of suitable electrolytes compatible with electrodes having high-aspect-ratio features. [ 6,8 ] Organosilicon polymers have considerable attention as biocompatible [9][10][11][12] and electrically insulating materials [13][14][15][16] with excellent stability. For example, poly(dimethylsiloxane) is widely utilized in prosthetic devices [ 11 ] and microfl uidic systems.

A group of crosslinked cyclic siloxane (Si-O) and silazane (Si-N) polymers are synthesized via solvent-free initiated chemical vapor deposition (iCVD). Notably, this is the first report of cyclic polysilazanes synthesized via the gas-phase iCVD method. The deposited nanoscale thin films are thermally stable and chemically inert. By iCVD, they can uniformly and conformally cover nonplanar surfaces having complex geometry. Although polysiloxanes are traditionally utilized as dielectric materials and insulators, our research shows these cyclic organosilicon polymers can conduct lithium ions (Li(+) ) at room temperature. The conformal coating and the room temperature ionic conductivity make these cyclic organosilicon polymers attractive for use as thin-film electrolytes in solid-state batteries. Also, their synthesis process and properties have been systemically studied and discussed.

“…Organosilicate glass ͑OSG͒ coatings, often fabricated by means of plasma-enhanced chemical vapor deposition ͑PECVD͒ processes using siloxane precursors, are receiving growing attention due to their application in the microelectronic, 1,2 optical, biomedical, [3][4][5] and environmental areas. Dense OSG coatings with dielectric constants as low as 2.8 have been successfully integrated into highperformance integrated circuits thanks to their excellent dielectric properties and their compatibility with state-of-the-art process technology.…”

Organosilicate glass ͑OSG͒ coatings with a range of compositions have been deposited using O 2 , He, and octamethylcyclotetrasiloxane as a precursor in a plasma-enhanced chemical vapor deposition process. Rutherford backscattering spectrometry and forward recoil spectrometry were used to determine the composition of the coatings. The measurements show that addition of carbon and hydrogen lowers the density of the coatings, effectively reducing the concentration of the polarizing species. The dielectric constant is further lowered by a reduction of the ionic and orientation polarizabilities. Fourier transform infrared measurements show that as more C and H are incorporated, the siloxane network is more frequently interrupted by terminal methyl ͑CH 3-͒ and H groups. Based on the experimental results a quantitative model for the OSG structure is proposed and the inverse infrared absorption cross sections of various absorption bands are determined, some of which for the first time. The structural model also makes it possible to calculate the average electronic polarizability of the various bond configurations in the OSG.
