“…Of course, in the case of carbon coatings produced on polymer substrates, the range of their properties is limited by the thermal resistance of the substrates themselves. Nevertheless, works on the use of carbon coatings are carried out both in the case of hard, wear-resistant polymers, such as PEEK [ 22 ], and those that are “soft”, such as PDMS [ 26 ]. The use of DLC coatings on substrates such as PDMS is inevitably combined with the appearance of wrinkles on the surface of polymers.…”

“…It is an issue that has been widely described in the literature [ 10 , 27 , 28 , 29 , 30 , 31 , 32 ]. Most often, wrinkles on modified PDMS surfaces are described as the result of mismatching the elasticity modulus of the coating and the polymer substrate [ 26 , 27 , 31 ]. However, when analyzing this issue in more detail, it is worth noting that the formation of wrinkles is the effect of mismatching the deformation of the formed coating when the compressive stress exceeds the threshold value [ 29 , 30 , 32 ].…”

The plasma modification of polydimethylsiloxane (PDMS) substrates is one way to change their surface geometry, which enables the formation of wrinkles. However, these changes are very often accompanied by the process of restoring the hydrophobic properties of the modified material. In this work, the RF PACVD device (radio frequency plasma-assisted chemical vapor deposition) was used, with which the plasma treatment of PDMS substrates was carried out in argon, nitrogen, oxygen, and methane atmospheres at variable negative biases ranging from 100 V to 500 V. The obtained results show the stability of contact angles for deionized water only in the case of surfaces modified by diamond-like carbon (DLC) coatings. The influence of the applied production conditions on the thickness (between 10 and 30 nm) and chemical structure (ID/IG between 0.41 and 0.8) of DLC coatings is discussed. In the case of plasma treatments with other gases introduced into the working chamber, the phenomenon of changing from hydrophilic to hydrophobic properties after the modification processes was observed. The presented results confirm the barrier nature of the DLC coatings produced on the PDMS substrate.

“…They showed that an increase of Ag content causes a decrease of transparency and optical bandgap and an increase of the Urbach parameter. Also, Alam et al [5] fabricated a-Ag: DLC by direct current plasma-enhanced chemical vapour deposition (PECVD) and showed favourable electron field emission properties with increases of the Ag content. Písarík et al [6] indicated antibacterial properties of Ag/DLC coating produced by dual pulsed laser deposition against Staphylococcus aureus and Pseudomonas aeruginosa.…”

We present an advanced image analysis study of the 3D surfaces of silver/diamond-like carbon nanocomposite films prepared by radio-frequency plasma-enhanced chemical vapour deposition. Atomic force microscopy data were analysed, with the goal to provide image analysis tools allowing for a better understanding of the structure-property correlation, with specific case for the present material. While the samples' fractal dimension decreased and the roughness increased with increasing deposition time, fractal succolarity showed no significant difference and relatively high values, describing high percolation, and fractal lacunarity decreased, in agreement with topographic entropy, which revealed uniformity in height distribution. In conclusion, the samples' microtexture shows a nearly uniform surface with a homogenous distribution of nanoparticles, due to the fabrication process and the emerging fractal nature of the nanocomposite, at all the considered deposition times. Fractal lacunarity and succolarity, currently not provided by commercial image analysis programmes, can be useful in advanced surface image characterization.
