Polymer nanocomposites are an interesting and rapidly growing class of novel materials with enhanced properties, even at low nanofiller loads. They are considered to be promising materials in a wide variety of applications, including automotive, aerospace, mechanics, electronics and biomedical system applications.
The structure, properties and their relationships in polymer nanocomposites strongly depend not only on the polymer matrix type, its average molar mass, its dispersity and the architecture of polymer chains, but also on the type, chemical composition, shape, size and content of nanoparticles and their compatibility with polymer matrix. Proper functionalization of nanomaterials can substantially improve polymer–filler compatibility and/or lead to new desirable features. Depending on these factors, nanoparticles can strongly influence mechanical, rheological and optical properties; flame retardancy; and the thermal and electrical conductivity of polymer matrices. It is also well-known that nanoparticles can change the thermal stability and degradation mechanism (including kinetics) of a polymer matrix. They may influence the mechanism of polymer matrix crystallization and facilitate formation of new crystalline structures.
This Special Issue of Nanomaterials will attempt to cover the most recent advances in polymer nanocomposites, including their preparation, compatibilization and processing, along with the properties and methods of their characterization. It will also report on nano-effects like entanglements, confinement and other phenomena connected to the incorporation of nano-size particles to polymer matrix and their influence on the behavior of macromolecules. Papers on applications of polymer nanocomposites in different sectors, ranging from mechanical engineering, automotive and buildings to electronics and biomedicine are welcome. I hope this Special Issue will contribute to a better understanding of polymer-based nanocomposite structure and properties, thus opening further application perspectives.
In this Special Issue, “Polymer Nanocomposites: Preparation, Characterization and Applications”, full research papers and reviews will be published.

Abstract: In this work nanohydroxyapatite (HAp) was functionalized with poly(ε-caprolactone) (PCL) using 1,6-hexamethylene diisocyanate as a coupling agent and then incorporated into polyoxymethylene copolymer (POM) matrix using extrusion technique. The obtained POM/HAp-g-PCL composites were investigated using FTIR, DSC, TOPEM DSC and TG methods. Mechanical properties using destructive and non-destructive ultrasonic methods, wettability and POM crystallization kinetics in the presence of HAp-g-PCL were also studied. Moreover, preliminary assessment bioactivity of the POM/HAp-g-PCL composites was performed using Kokubo method. It was found that the introduction of HAp-g-PCL to POM matrix has a limited effect on the phase transitions of POM as well as on its degree of crystallinity. Importantly, HAp grafted with PCL caused a significant increase of POM thermal stability – from 292°C for pristine POM to 333°C for POM modified with 2.5% of HAp-g-PCL; if unmodified HAp was used, a distinct decrease in the POM thermal stability was observed. Crystallization kinetics studies confirmed that in small amounts HAp-g-PCL can act as a nucleating agent for POM crystallization process. Moreover, it was found that incorporation of HAp-g-PCL, although slightly decreases mechanical properties of POM composites, improves crucial parameter in biomedical applications - in vitro bioactivity.
