The method of TiO 2 -anatase film preparation on cotton and viscose fabric surfaces using the sol-gel process and microwave treatment is presented. Microwave treatment was used to change the amorphous TiO 2 form to anatase directly on the fabrics. The influence of microwave treatment conditions on the obtainable polymorphic form of TiO 2 was examined. Fabrics were pretreated with low-temperature air plasma (30 min). The root mean square height in the selected area increased from 44 to 166 nm (cotton) and from 9 to 112 nm (viscose). Infrared analysis showed the new band at 1748 and 1732 cm -1 corresponding to C=O stretching for plasma-treated cotton and viscose textiles, respectively. The plasma pretreatment also improved the wetting properties by TiO 2 sol and increased the surface free energy of fabrics. TiO 2 film thickness was 180 nm (12 %wg. Ti) and 140 nm (3 %wg. Ti) for cotton and viscose, respectively. TiO 2 -modified cotton reduced the nicotine concentration three times more and TiO 2 -modified viscose was two times higher under sunlight compared to raw fabrics. No changes in strength were observed for TiO 2 -modified cotton, while the strength of TiO 2 -modified viscose decreased about 45 %. No effect of UV irradiation on cotton and a slight reduction of the strength of raw viscose (7 %) and TiO 2 -modified viscose (16 %) were observed. The Ti contents after washing decreased from 12 to 11 % (cotton) and from 3 to 2.6 % (viscose). The presented method allows obtaining TiO 2 film-anatase on the cotton and viscose fabrics, but its total effectiveness is better for cotton fabrics.

In this work, the analysis of the plasma modification of polydimethylsiloxane (PDMS) substrates was conducted. The influence of the modification onto the changes occurred within the geometrical structure and chemical composition of the surface was analyzed. Due to the study of the atomic force microscopy, it was possible to determine the relationships between the surface development and applied process parameters, defining the conditions facilitating to obtain isotropic or anisotropic orientations of wrinkles. A precise analysis of the chemical composition of the surface, executed before and after the modification processes, enabled to define the changes in their elementary composition. Moreover, the modification influence onto the changes of the contact angle and the surface free energy were also analyzed. So, based on the research it was stated that the increase of value of the surface free energy is proportional to the sp 3 phase contents in the DLC coatings.
