“…The resolution can get to 0.05 nm with 1200 grooves/mm grating so that this apparatus allows us to study emission lines in the 200 nm to 1100 nm range with a spectral resolution sufficient for acquisition of ro-vibrationnal molecular band. More detail can be found in [5] and [6].…”

TiO2-like polymer films were synthesized by inductively coupled plasma in pulsed radio-frequency (RF) modes. The plasma chemistry, studied by optical emission spectroscopy, showed that the radicals and fragments formed in the discharge were dependent on the precursor, and that the species density in the plasma gas is as a function of flux de gas that is used to carry the monomer into the plasma reactors.

“…As it seen in Figure 2, a distinct peak at 1108 cm -1 together with two less manifest peaks at 806 and 467 cm -1 appeared corresponding to the vibration absorption of Si-O-Si. However, a perceivable peak C-H stretch band at 3000-3100 cm -1 , which is corresponds to aromatic C-H stretching vibration at 3027 cm -1 , as well as the characteristic peaks at 2921, 2854, 1733, 760, and 700 cm -1 are associated with the characteristic vibration of methyl (CH 3 ), methylene (CH 2 ), carbonyl (C = O), plane C-H bending, and benzyl groups, respectively (33,34). Therefore, the evidence confirms that the silica and P(MMA-co-St) are definitely formed.…”

An appropriate approach has been used for the preparation of silica/P(MMA-co-St) hybrid nanoparticles through converting previously prepared inverse miniemulsions into a direct miniemulsion and consequently, using the droplet nucleation polymerization technique. In the early stage of the procedure, silica particles were synthesized from TEOS in the presence of NH 4 OH or HCl as a catalyst through a base or acid-catalyzed sol-gel process. TEOS, ethanol and tirmethoxyvinylsilan were mixed in MMA:St (50:50) to create the inverse miniemulsion I, similarly CTAB, NH 4 OH/HCl and distilled water were dispersed into MMA:St (50:50) and called inverse miniemulsion II. Then, the two mentioned inverse miniemulsions were emulsified in water to achieve direct miniemulsion. The nature of the catalyst and TEOS concentration varied, for the aims of investigation, their effect on the morphology and size of hybrid nanoparticles. This route provided a unique process for silica/polymer hybrid nanoparticles production, avoiding organic solvents. Transmission electron microscopy micrographs revealed that, the morphology of the hybrid nanoparticles can be controlled by the nature of the catalyst.

“…Extensive studies have been done to assess the effects surface modification of biomaterials using a wide range of oxygen containing monomers on the interaction of cells and tissues at the biomaterial interface 9,18–20 . Amine-based monomers are also a common oxygen-free alternative for grafting molecules such as allylamine and acrylamides 5,21–24 and mixtures of these monomers to deposit co-polymerized films on the surface of the materials have also been investigated 25–28 . These one-step methods alter the surface of biomaterials at a depth of a few hundred angstroms to nano-meters while preserving the underlying biomaterial bulk properties.…”

We have performed three distinct plasma enhanced chemical vapor deposition procedures that can be widely and consistently used in commercially available plasma systems to modify the surface of hydrocarbon-based biomaterials such as polypropylene. In particular, we have evaluated the feasibility of these procedures to provide consistent and stable charged substrates to perform layer-by-layer (LbL) coatings. Surface characterization of both plasma and LbL coatings were done using X-ray photoelectron spectroscopy, attenuated total reflection-Fourier transform infrared spectroscopy, contact angle measurements and surface staining. Results showed successful surface grafting of functional groups in all plasma procedures that led to increased hydrophilicity and uniform LbL coatings with different efficiencies. © 2018 Wiley Periodicals, Inc.
