“…Using this method a series of samples in which silver nanoparticles diffused deep into the porous matrix were obtained. The thermal deposition of metals into the porous layer took place at the same parameters as the deposition by electrothermal diffusion, but without applying an electric potential to the sample [28][29][30].…”

In this work composite structures based on a porous silicon were obtained and studied. Porous matrices were formed by electrochemical etching in aqueous solutions of hydrofluoric acid. Based on the obtained substrates, por-silicon (Si)/silver (Ag) and por-Si/zinc oxide (ZnO) composite structures were formed. These composites were functionalized by various methods (electro (E)-, thermo (T)-, electrothermal exposure) as a result of which the structures were modified. When studying the samples by scanning electron microscopy (SEM), it was concluded that silver nanoparticles actively diffused into the pores under these technological modes of functionalization. The por-Si/Ag and por-Si/ZnO composite structures were also studied using the following methods: infrared (IR) spectroscopy and Raman ultrasoft X-ray emission spectroscopy. Also, the photoluminescent characteristics of the samples were studied. Based on the obtained results, it was concluded that functionalization methods actively change the phase composition of structures and the optical properties of composites.

In this work, we studied the functionalized por-Si/Ag composite structures by the contact angle method using the “Contact Angle Measurement System JGW-360A”. The hydrophobic / hydrophilic properties of the studied structures were analyzed. Were studied changes in surface functional groups with various functionalization methods. Wetting gulls were also determined for different series of samples: porous silicon (θ ≈ 580), a porous matrix with a silver layer (θ ≈ 340), and a porous matrix functionalized by electro-thermal diffusion (θ ≈ 410). Were drawn the conclusions about the effect of oxide phases on the hydrophobic/hydrophilic properties of the studied samples.
