In this paper, the hydrophobic effect of the functional group in a hybrid ceramic synthesized from tetraethyl orthosilicate (TEOS) and polydimethylsiloxane (PDMS) is investigated. The hybrid ceramics were synthesized using di-butyl-di-di-tin laurate (DBTL) as a polycondensation catalyst and different concentrations of the polysiloxane chain varying from 20-40%w. Infrared spectroscopy confirmed the formation of the hybrid material, observing the corresponding signals for the siloxane bond (Si–O–Si) corresponding to the silica network, inorganic fragment (1100 cm–1 ) and those corresponding to the polymer chain (785 cm–1 ) besides, the Si–C bond of the polymer is presented at 1250 cm–1 . The amino functional group was identified as a low intensity signal at 1300 cm–1 (N–C) and 1204 cm–1 (Si– N); on the other hand, the phenyl group was present at 3080 cm–1 for the C–H group of the aromatic ring and with the C=C bond of the ring at 1429, 794 and 845 cm–1 . While the hydrophobic character was evaluated with the contact angle  obtaining a hydrophobic to superhydrophobic behavior with  de 110-130º.

“…It should be mentioned once again that some nanoparticles are provoked to form the relief as novel coatings [80][81][82][83][84], which are useful not only for general optoelectronics but for biomedicine and biotechnology. Classical optoelectronic materials and natural ones were considered as the substrates for the perspective coatings, which influence the basic material properties as well.…”

Due to the high demand for optoelectronics for use in new materials and processes, as well as the search for their modeling properties, the expansion of the functionality of modified materials using nanotechnology methods is relevant and timely. In the current paper, a specific nanotechnology approach is shown to increase the refractive and photoconductive parameters of the organic conjugated materials. The sensitization process, along with laser treatment, are presented in order to improve the basic physical–chemical properties of laser, solar energy, and general photonics materials. Effective nanoparticles, such as fullerenes, shungites, reduced graphene oxides, carbon nanotubes, etc., are used in order to obtain the bathochromic shift, increase the laser-induced change in the refractive index, and amplify the charge carrier mobility of the model matrix organics sensitized with these nanoparticles. The four-wave mixing technique is applied to test the main refractive characteristics of the studied materials. Volt–current measurements are used to estimate the increased charge carrier mobility. The areas of application for the modified nanostructured plastic matrixes are discussed and extended, while also taking into account the surface relief.

“…PECVD SiCN:H films possess reduced hydrophilic or even hydrophobic with average water contact angle (CA), ranging from 56 to 105 • depending on deposition technique, and synthesis conditions [46,64,65]. This makes them suitable for biomedical applications, where it helps to prevent protein adsorption and the lubricity of the urinary catheters, as well as material creation, as a sublayer to achieve a good adhesion between the coating and the substrate [66][67][68]. In this work we applied an approach of surface modification by plasma treatment which is often used to improve the hydrophilic properties of polymers [69,70], and also for modification of low-k materials to reduce bulk damage [71].…”

PECVD SiC:H (SiCN:H) films were produced using tetramethylsilane (TMS) as a precursor in a mixture with inert helium or ammonia as a source of nitrogen. Mild plasma conditions were chosen in order to prevent the complete decomposition of the precursor molecules and promote the incorporation of the fragments of precursor into the film structure. The effect of deposition temperature and composition of gas mixture on the chemical bonding structure, elemental composition, deposition rate, and optical properties (transmittance, optical bandgap, and refractive index) of films have been examined. Use of the chosen deposition conditions allowed them to reach a relatively high deposition rate (up to 33 nm/min), compared with films produced in high plasma power conditions. Use of ammonia as an additional gas led to effective incorporation of N atoms in the films. The composition of the films moved from SiC:H to SiN:H with increasing of ammonia content to P(NH3)/P(TMS) = 1. The refractive index and optical bandgap of the films varied in the range of 1.55–2.08 and 3.0–5.2 eV, correspondingly, depending on the film composition and chemical bonding structure. The effect of treatment of SiCN films deposited at 400 °C by plasma of He, O2 or NH3 were studied by X-ray photoelectron spectroscopy, atomic force microscopy, and contact angle measurements. It was shown that plasma treatment significantly changes the surface characteristics. The water contact angle of the film was changed from 71 to 37° after exposure in the plasma conditions.
