Special Issue Information

Dear Colleagues,

This Special Issue “Advances in Polymer composites and Nanocomposites” was born as a commemorative Special Issue in honor of Professor José M. Kenny and his recent retirement from the academic world, being based on subjects relevant to his scientific career and dedicated to scientific research and industrial developments related to materials science and technology, embracing, in particular, the world of polymers, composites and the progress on polymer nanotechnologies.

Prof. José Kenny is Full Professor of Materials Science and Technology at the Department of Civil and Environmental Engineering of the University of Perugia in Terni, Italy. He is also the President of the Board of the European Centre for Nanostructured Polymers.

Prof. Kenny earned his PhD at the University of the South in Argentina, and since 1993, he has worked at the University of Perugia, where he formed and coordinated the Laboratory of Materials Science and Technology. His main areas of research are the processing of polymers, composites and nanocomposites for applications in several advanced sectors: aerospace, automotive, biomedicine, food packaging, alternative energy and building. Moreover, in recent years, the research of Prof. Kenny has mainly been devoted to biopolymers (bio-based and biodegradable), recycling (circular economy) and the environmental impacts of polymer-based materials.

In more than 35 years of academic work, Prof. Kenny has authored more than 680 scientific publications in indexed international journals (Scopus h=100) related to the processing, characterization and applications of polymers, composites and nanocomposites, achieving more than 35,000 citations. Moreover, Prof. Kenny is a member of the editorial boards of several international scientific journals in the field of polymers. Prof. Kenny has coordinated numerous Italian and international scientific, technological and education projects and been a visiting professor at several European and American universities and research centers. He was President of the European Society for Advanced Materials and Process Engineering (SAMPE) in the period 2001-2002, and he received the SAMPE Fellow Award in 2011 and the RAICES Award in 2012, granted by the Argentine Ministry of Science and Technology. During the period 2015-2021, Prof. Kenny was appointed as Scientific Attaché at the Italian Embassy in Argentina.

Nowadays, paying deep attention to the future of polymer-based materials is required, not only from a functional point of view but also by taking into acocunt their potential end-of-life state and environmental impacts. Growing interest in bio-polymers, both bio-based and biodegradable polymers, is being promoted, while the recycling of aspects of polymeric materials is becoming very relevant from industrial and socio-economic points of view.

Therefore, with this Special Issue, we want to present a general vision of the polymeric world, focusing attention on polymers, composites, nano-composites, nanoparticles, elastomers, bio-based and biodegradable polymers, advanced materials, smart and functional materials, structure–properties relationships and advances in processing and characterization techniques.

Over the past few years, polymer nanocomposites have garnered a significant amount of interest from both the scientific community and industry due to their remarkable versatility and wide range of potential uses in various fields, including automotive, electronics, medicine, textiles and environmental applications. In this regard, this study focuses on the influence of a compatibilizer rubber on a nanocomposite incorporating graphene nanoparticles (GNPs), with a polymer matrix based on a blend of polypropylene (PP) and polyethylene terephthalate (PET). This effect has been investigated on both isotropic samples and on anisotropic/spun fiber samples. The influence of the compatibilizer rubber on morphological, rheological and mechanical properties was analysed and discussed. Mechanical and morphological properties were evaluated on both isotropic samples obtained by compression moulding and melt-spun fibers. The addition of the rubbery compatibilizer increased the viscosity, improving interfacial adhesion, and the same effect was observed for the melt strength and breaking stretching ratios. Mechanical properties, including the elastic modulus, tensile strength and elongation at break, improved in both types of samples but more significantly in the fibers. These improvements were attributed to the orientation of the matrix, the formation of PET microfibrils, and the reduction in the size of graphene nanoparticles due to the action of the elongational flow. This reduction, facilitated by the elongation flow and the action of the compatibilizer, improved matrix–nanofiller adhesion due to the increased contact area between the two polymeric phases and between the filler and matrix. Finally, a transition from brittle to ductile behaviour was observed, particularly in the system with the compatibilizer, attributed to defect reduction and improved stress transmission. Full article

In the current contribution, bacterial nanocellulose obtained from a by-product of Kombucha tea production and vegetal nanocellulose isolated from milled rice husks were employed as fillers of PLA-based composites prepared by intensive mixing followed by compression molding. Given the challenges associated with the incorporation of nanocelluloses—initially obtained as aqueous suspensions—into melt compounding processes, and also with achieving a proper dispersion of the hydrophilic nanofillers within PLA, three different nanofibrils incorporation strategies were studied: i.e., direct mixing of dried milled nanocelluloses and PLA; masterbatching by solvent casting of native nanocelluloses followed by melt compounding; and masterbatching by solvent casting of acetylated nanocelluloses followed by melt compounding. Composites with varying filler content (from 0.5 wt.% to 7 wt.%) were characterized in terms of morphology, optical properties, and mechanical performance. Results revealed the relative suitability of each strategy employed to promote nanocelluloses dispersion within the PLA matrix. PLA/nanocellulose masterbatches prepared by solvent casting proved to be particularly useful for feeding the nanocelluloses into the processing equipment in a dry state with limited hornification. Acetylation also contributed to a better dispersion of both nanocelluloses within the PLA matrix, although no clear positive impact on the mechanical properties of the films was observed. Finally, filler loading played an important role in the films’ properties by increasing their stiffness while reducing their translucency. Full article
