Diamond like carbon coatings were manufactured by dual frequency plasma enhanced chemical vapour deposition method on a poly(ether‐ether‐ketone) substrates. In the presented work, modified surfaces were characterized in terms of the tribological parameters, surface topography, mechanical properties and the chemical composition. Obtained results of the research indicate that the highest resistance against wear, which means the most probable application abilities, presented the carbon coatings created in RF plasma with the use of nitrogen for the preliminary stage of preparation. Due to that modification, it was possible to limit the coefficient of friction from the value of c.a. 0.4–0.26 and 35 times decrease the specific wear rate. The DLC coatings deposited in RF plasma exhibited hardness of about 2 GPa with a relatively low contribution of sp3 phase and surface roughness.

New biodegradable and biocompatible composites are continuously developed for biomedical applications (e.g. from drug delivery devices to tissue engineering scaffolds). Properties of such systems may depend on their morphology and structure, which are attained after their processing and therefore, the study of the crystallization kinetics has a particular relevance. The crystallization kinetics of hydroxyapatite-filled poly(butylene terephthalate-co-alkylene dicarboxylate)s has been studied under non-isothermal conditions, using a wide range of cooling rates and different kinetic models. Based on our results, nanohydroxyapatite (nHAp) particles were found to effectively act as additional nucleation sites for poly(butylene terephthalate-co-succinate) (PBST), giving rise to an increased crystallization rate with respect to pure PBST. However, the overall growth rate of HAp nanocomposites decreased compared to the corresponding homopolymers with longer aliphatic dicarboxylic acids (i.e. adipic and sebacic acid derivatives). In order to clarify this point, the activation energy for non-isothermal crystallization was evaluated using the Friedman method and significant differences were observed, suggesting a disturbing effect of nanoparticles on the motion of molecular chains that hindered their capability to reach the growing crystallization front. Isoconversional methods provided a good understanding of the kinetics of the crystallization process and significant information regarding the activation energy, relative crystallinity, and global and local Avrami exponents.
