Special Issue Information

Dear Colleagues,

The continuous development and appearance on the market of new high-performance reinforcing nanomaterials in different compositions and geometries (nanoparticles (NPs), nanosheets, nanorods, and nanotubes) has constituted a strong challenge for researchers and manufacturers in the design of new functional filled materials adapted to various targeted industries. In particular, the field of polymer nanocomposites (NCPs) constitutes a category of particular interest in this sector. It has been the subject of much work and research, as NCPs have great potential for many applications (automotive, electronics, biomedical, packaging, etc.).

Due to the large specific surface area of nanofillers, the exchange at the interface between the polymer and the NPs is quite important. This results in the transfer of the properties of the NPs to the polymer matrix. Therefore, the properties of the interface affect and can dominate the macroscopic properties of NCPs.

Despite the progress and results obtained, the overall performance of polymer matrix nanocomposites is sometimes insufficient for emerging industrial applications, which require the combination of various properties (electrical, thermal, electromagnetic shielding, etc.). Thus, NCPs are still an exciting field of research for both the academic and industrial communities.

Considering the great importance of this fascinating area of research, the goal of this Special Issue is to present a selection of reference papers, reviews, or communications collecting the latest results in the field of polymer nanocomposites, so they can enrich current and future literature data.

Recent advances in polymer fabrication methods related to nanofiller–polymer materials are expected. Both synthetic and natural fillers with thermoplastic-, thermoset-, and elastomer-based nanocomposites are considered. The mechanical, dielectric, and rheological methods, as well as surface and interfacial characterization in the processing of nanocomposites, are other challenging topics that are welcomed in this issue.

 Keywords: polymer nanocomposites (NCPs); synthetic and natural nanofillers; 3D printing and additive manufacturing of NCPs; rheology and processing of NCPs; nanofiller–polymer interfaces; advanced fabrication methods of NCPs; recycling of NCPs

The present review relates to the field of nanocomposite materials comprising a thermoplastic nanofibrillar phase dispersed in a matrix that is also thermoplastic. The fact of forming the nanofibrillar phase in situ during melt processing gives it the role of a reinforcing nanofiller for thermoplastic materials. This paper discusses the major factors influencing the formation of self-reinforced nanofibrillar polymer composite (NFC) materials throughout manufacturing steps. More specifically, the rheological considerations allowing the prediction of the in situ nanofibrillation during melt blending and post-processing as well as the methods of production of these polymer nanocomposites are described. The major challenges related to the future development in the field of NFCs are addressed. The concept of self-reinforced nanofibrillar polymer materials shows great potential in lightweight eco-design processes and represents a new approach to polymer nanocomposite recycling for a variety of industrial applications.
