Special Issue Information

Dear colleagues,

In the last two decades, the development of renewable and non-toxic compounds for industrial production has become of paramount importance due to the depletion of fossil resources and hence the rising price, and environmental problems like climate change. This has raised the interest in reducing using petroleum-based monomers and substituing them with novel, eco-efficient and biodegradable substitutes. In other words, new novel monomers need to be designed and tested to replace bisphenol derivatives that are toxic and environmentally unfriendly.

Using novel polymers has imparted multifunctionality to composite materials. Novel polymer composites combine properties such as ionic conductivity, thermal conductivity and hydrophilicity in addition to promising thermo-mechanical properties. For example, interpenetrating polymer networks (IPNs) that are defined as a combination of at least two polymers that form a network can be promising host matrix for polymer composites because each network component will impart different properties or contribute to multiple properties of the resultant composite.

The aim of this Special Issue is to highlight the importance of using molecular simulation techniques in modelling, testing and tuning novel and/or bio-based polymeric materials and their composites for various applications in the aerospace, automotive and energy industries.

We investigated the interfacial properties of symmetric ternary An/AmBm/Bn and An/Am/2BmAm/2/Bn polymeric blends by means of dissipative particle dynamics (DPD) simulations. We systematically analyzed the effects of composition, chain length, and concentration of the copolymers on the interfacial tensions, interfacial widths, and the structures of each polymer component in the blends. Our simulations show that: (i) the efficiency of the copolymers in reducing the interfacial tension is highly dependent on their compositions. The triblock copolymers are more effective in reducing the interfacial tension compared to that of the diblock copolymers at the same chain length and concentration; (ii) the interfacial tension of the blends increases with increases in the triblock copolymer chain length, which indicates that the triblock copolymers with a shorter chain length exhibit a better performance as the compatibilizers compared to that of their counterparts with longer chain lengths; and (iii) elevating the triblock copolymer concentration can promote copolymer enrichment at the center of the interface, which enlarges the width of the phase interfaces and reduces the interfacial tension. These findings illustrate the correlations between the efficiency of copolymer compatibilizers and their detailed molecular parameters. Full article

Recently, a new generation of polymerised ionic liquids with high thermal stability and good mechanical performances has been designed through novel and versatile cycloaliphatic epoxy-functionalised ionic liquids (CEILs). From these first promising results and unexplored chemical structures in terms of final properties of the PILs, a computational approach based on molecular dynamics simulations has been developed to generate polymer models and predict the thermo–mechanical properties (e.g., glass transition temperature and Young’s modulus) of experimentally investigated CEILs for producing multi-functional polymer materials. Here, a completely reproducible and reliable computational protocol is provided to design, test and tune poly(ionic liquids) based on epoxidised ionic liquid monomers for future multi-functional thermoset polymers.
