Synthetic polypropylene (PP) is used extensively in many fields of medicine. On the one hand, it is utilized in the manufacture of medical equipment: syringes, storage, transport, electric cables, etc. On the other hand, synthetic, nonabsorbable isotactic PP (iPP) is often used to perform meshes for hernia and pelvic organ repair operations, as well as in urinary incontinence. Products that release in time from meshes are depending on the conditions in which they are utilized, can produce undesirable reactions for the human body. For this reason, nonabsorbable synthetic PP was replaced in surgical sutures and meshes with bio polypropylene (bio PP). The chapter analyzes the specific characteristics of these polymers as well as their degradation due to the influence of different factors: humidity, perspiration, temperature, and presence of bacteria. Obtaining new composite materials with PP as matrix and metal powders as fillers is considered as a possibility of their use in vital problems such as cancer detection and treatment. These allow the emergence of new strategies in the design of biosensors that use nanocomposite materials with different fillers and polymeric films. The chapter analyzes the characteristics of new composite materials with PP matrix and metallic powders of iron (Fe).

In this work, morphological, electrical, and dielectric performance of nylon copolymer (PA6, 66)/ethylene propylene diene rubber (EPDM) blends were systematically studied with reference to blend ratio and compatibilisation. As the concentration of PA6, 66 and the percentage of compatibiliser in the blend increases the resistivity values decreases. The existence of two phases, PA6, 66 and EPDM with different conductivity and interfacial polarization are responsible for the increase in the dielectric properties of the blends. Compatibilisation of the blends improved the dielectric constant of the blend system. Addition of 2.5% of compatibiliser gave the highest value of dielectric constant. At a high concentration of EPM‐g‐MA, the polarity of the compatibilised blends was found to be increased, which resulted in the substantial increase in the value of loss and dissipation factor. The dielectric values of the blends were correlated with blend phase morphology. Finally the experimental data was compared with various theoretical predications. POLYM. ENG.

The polymer nanocomposite structures based on isotactic polypropylene and nickel nanoparticles were obtained and studied by scanning electron microscopy, UV-Vis, FT-IR, and dielectric spectroscopy. IR studies show that the introduction of nickel nanoparticles into the polypropylene matrix does not change the chemical structure of the polymer, that is, nickel nanoparticles are not in the chemical, but in physical interaction with the polymer. It is also shown that as the frequency increases, the value of the permittivity of the nanocomposite based on PP/Ni does not change, and this is due to the lack of polarization processes. The value of the dielectric loss tangent depends on the Ni concentration with an extremum, that is, with an increase in the content of Ni nanoparticles, the value of the dielectric loss tangent decreases and at a content of 3% Ni in the polymer, the value of tan δ is minimal and a further increase in the concentration leads to an increase in the dielectric loss tangent. A sharp decrease in the resistivity at 383 K, 413 K, and 423 K, respectively, for the nanocomposites PP/3% Ni, PP/5% Ni, and PP/10% Ni is explained by the destruction of the crystalline phase of the polymer and the increase in electrical conductivity of the nanocomposites.
