Special Issue Information

Dear Colleagues,

Polymer nanocomposites have attracted considerable attention from both academic and industrial points of view owing to the enhanced properties that can be achieved for new materials as compared with unfilled polymers. Property enhancement depends on several factors, in particular on the dispersion state of the nanofiller. Metal nanoparticles are of great interest in nanotechnology due to their fascinating properties, small size, and surface plasmon behavior and are incorporated into polymer matrices to improve the performance properties. The method of incorporation of these nanoparticles is crucial since their properties are shape- and size-dependent. Metal-based hybrid fillers have been shown to be more effective in improving the performance of the nanocomposite than the individual components due to the synergetic effect. A wide range of applications has been found for metal nanoparticle composites that are dependent on the nanoparticle–polymer combination.

This Special Issue invites original papers and reviews reporting on recent progress in the following areas:

-Preparation methods for metal and metal oxide polymer nanocomposites;

-Preparation methods for metal hybrid polymer nanocomposites (clay–metal, carbon nanotubes–metal, graphene–metal);

-Morphology of metal nanoparticles, metal hybrids, and metal and metal hybrid polymer nanocomposites;

-Properties of metal and metal hybrid polymer nanocomposites;

-Applications of metal and metal hybrid polymer nanocomposites.

Three different matrices were used to obtain polymer and composite samples containing 0.5 wt % and 1.0 wt % of silver nanoparticles, respectively. The aim of this study was to [...] Read more.
Acrylonitrile butadiene styrene/silver nanoparticles (ABS/AgNPs) composites were manufactured through the plastic processing method. Three different matrices were used to obtain polymer and composite samples containing 0.5 wt % and 1.0 wt % of silver nanoparticles, respectively. The aim of this study was to examine physicochemical properties and stability of the materials in the in vitro conditions for two years. The results showed that composites made from amorphous matrices had comparable mechanical properties after incorporation of AgNPs. The values of Young modulus and tensile strength increased after the first and second year of investigation. Silver nanoparticles did not alter the surface parameters—e.g., roughness and contact angle also retained stable values after the in vitro incubation in water solution. The scanning electron observation revealed homogeneous distribution of silver modifier in all the matrices. The 24-month incubation of materials proved the stability of the composites microstructure. The DSC analysis revealed that addition of AgNPs may decrease glass transition temperature of the composite materials which was also reduced after 12 and 24 months of incubation. The attenuated total reflectance–Fourier transform infrared (ATR-FTIR) spectroscopic studies did not indicate significant changes in the ABS matrices either upon their modification with AgNPs or after the long-term testing. The conducted studies proved that all the composites are stable and may be used for a long-term working period. Full article

Composite materials based on polypropylene modified with silver nanoparticles (PP/AgNPs) were manufactured using injection molding and extrusion. Two different matrices were used to prepare the samples consisting of 0.5 and 1.0 wt. % of silver nanoparticles, respectively. The aim of this study was to assess whether silver nanoparticles (AgNPs) could influence the stability of a polymer matrix during the 24-month period of the in vitro testing. The results indicated that composites with silver nanoparticles displayed the significantly higher Young modulus and tensile strength after the first and second year of investigation. Moreover, the incorporation of nanoparticles into the matrix slightly increased the roughness and contact angle values and the parameters remained stable after the in vitro incubation. The two-year immersion of materials in the deionized water proved that the microstructure of composites did not change. The DSC analysis revealed that the material incubation resulted in a slight reduction in the melting temperature and degree of crystallinity of PP. The addition of nanoparticles to polymer matrices led to the increase in content of β crystals in the crystalline phase of PP, which was revealed in the long-term in vitro tests. The XRD measurement also showed the heightened surface crystallinity. The conducted studies have proved that all composites are stable over a period of 24 months. Such behavior suggests that the tested materials can be used as biomaterials. Full article
