“…Considering the thin films without silver, all present approximately the same value of contact angle, between 27 and 35°. The value for the SiO 2 thin film is in agreement with those reported by other authors while for the polymeric thin film the measured value is lower than those presented in other papers and lower than the one obtained for the bulk polymer target (80°) 33, 34. This fact indicates the presence of chemical groups on the outer surface of the thin film that chemically interact with water, such as OH and COOH, which is in agreement with the results observed in the FTIR spectra.…”

Thin nanocomposite hybrid films were deposited by r.f. magnetron sputtering. These were composed of of SiO2, poly(propylene) (PP) and SiO2/PP, with Ag contents varying from 0 to 30 at.‐%. The influence of metal concentration on the properties of the deposited surfaces was evaluated. The chemical composition, chemical structure, morphology, dynamic wettability behavior, and microstructure were studied. The overall properties of the inorganic/organic system are more influenced by those of the ceramic fraction than by the polymeric one. The hysteresis of the contact angle shows that all the surfaces interact with water and that the presence of the metallic element increases reactivity in an aqueous medium. These results show promising applications in the biomedical field particularly in those that use silicon as a biomaterial for implants.

“…The density of the matrix was taken at 1.9 g · cm −3 measured for films without Cu NPs. The calculation of the filling factor from the known elemental composition was described in . In this case, the equation is as follows:

f = \frac{\frac{m_{C u} + {m^{'}}_{O}}{ρ_{N P s}}}{\frac{m_{C} + m_{H} + {m^{″}}_{O}}{ρ_{m a t}} + \frac{m_{C u} + {m^{'}}_{O}}{ρ_{N P s}}}

where m Cu , m C , m H , m′ O and m″ O are the masses of copper, carbon, hydrogen, oxygen bound to copper and oxygen bound in the a‐C:H matrix, respectively.…”

In the present study is shown a novel vacuum‐based technique that enables production of hard polymeric nanocomposite coatings with metal (Cu) nanoparticles. This method is based on the use of gas aggregation source (GAS) of Cu nanoparticles and plasma‐enhanced chemical vapour deposition of a‐C:H matrix that was deposited in a mixture of Ar and n‐hexane on the substrates placed on the powered RF electrode. This approach makes it possible to control independently both the properties of the matrix by variation of the applied RF power and the amount of incorporated Cu nanoparticles that may be adjusted by operational parameters of the GAS. Characterisation of the films in terms of their chemical composition, morphology, optical and mechanical properties is described here alongside with description of Cu nanoparticles production using GAS with variable aggregation length.

“…Plasma polymerization is a versatile technology that has a number of inherent advantages, such as wide range of monomers can be used, synthesis does not require the use of solvents and oxidants and thus gives a product with less contamination and superb stability towards high temperature, intensive light and strong electric fields [9][10][11]. Recent years have shown growing interest in the preparation of plasma polyaniline and their composite films due to the new challenges of their use as organic semiconductors [12][13][14][15]. The goal is to achieve materials with specified set of electrical and optoelectronic properties for the manufacture of luminescent and photosensitive transport layers of uniform and homogeneous thickness and to be used as nonlinear optical (NLO) materials.…”

Plasma polymerization of aniline is carried out in a radiofrequency plasma reactor and the effect of polymerization time is examined in the structural, optical and optoelectronic properties of deposited films. Conjugated structures of polyaniline like films are obtained with unique and broad optical absorption band in the ultraviolet and entire visible region. The width of the absorption band increases and hence the optical band gap decreases with polymerization time. The optical constants are extracted by Swanepoel method and the optical dispersion parameters are determined by employing the WempleDiDomenico single oscillator model. The films exhibit similar thermal stability in air and argon atmosphere in the region of interest for optoelectronic applications. The photoluminescence study suggests, like the chemically synthesized polyaniline, the benzenoid units to be responsible for fluorescence. The fluorescence peaks due to defect states confirm the formation of spectroscopic units in the plasma polyaniline films.
