Special Issue Information

Dear Colleagues,

The application and characterization of polymer composites has witnessed significant growth and innovation in recent years. This multidisciplinary domain encompasses the design, fabrication, testing, and utilization of polymer composites across various industries, including the aerospace, automotive, construction, renewable energy, biomedical industries, among many others. Characterization plays a pivotal role in understanding and optimizing the performance of polymer composites. Advanced analytical techniques, including microscopy, spectroscopy, mechanical testing, and non-destructive evaluation, enable researchers to elucidate the structure–property relationships of composites. Polymer composites, consisting of a polymer matrix reinforced with fibers, particles, or additives, offer a diverse array of material structures (films, coatings, and hydrogels), making them suitable for a wide range of applications, including soft robots, wearable devices, energy storage materials, artificial skins, and sensors. Future research directions may include smart and multifunctional composites and novel applications in emerging technologies. This dynamic field offers exciting opportunities for researchers, educators, and industry professionals to shape the future of materials and technology.

Composites revolutionize material performance, fostering innovation and efficiency in diverse sectors. Elastomer-based polymeric composites are crucial for applications requiring superior mechanical strength and durability. Widely applied in automotives, aerospace, construction, and consumer goods, they excel under extreme conditions. Composites based on recycled rubber, fortified with reinforcing fillers, represent a sustainable material innovation by repurposing discarded rubber. The integration of reinforcing agents enhances the strength and resilience of this composite, and the recycled polymeric matrix offers an eco-friendly alternative to virgin elastomers, reducing their environmental impact. Devulcanized rubber, with inherently lower mechanical properties than virgin rubber, requires enhancement of its quality for reuse in a circular economy: considerable amounts of recycled tire rubber can only be applied in new tires if the property profile comes close to the one of the virgin rubber. To achieve this, model passenger car tire and whole tire rubber granulates were transformed into elastomeric composites through optimized devulcanization and blending with additional fillers like carbon black and silica–silane. These fillers were chosen as they are commonly used in tire compounding, but they lose their reactivity during their service life and the devulcanization process. Incorporation of 20% (w/w) additional filler enhanced the strength of the devulcanizate composites by up to 15%. Additionally, increased silane concentration significantly further improved the tensile strength, Payne effect, and dispersion by enhancing the polymer–filler interaction through improved silanization. Higher silane concentrations reduced elongation at break and increased crosslink density, as it leads to a stable filler–polymer network. The optimal concentration of a silica–silane filler system for a devulcanizate was found to be 20% silica with 3% silane, showing the best property profile. Full article
