Special Issue Information

Dear Colleagues,

This Special Issue will focus on the latest advances in polymer-based fiber composites. Fiber-reinforced composites are composed of two or more constituent materials with significantly different physical or chemical properties. They are produced by integrating reinforcing fillers with a thermoplastic or thermoset polymer matrix, resulting in synergistic mechanical properties that cannot be achieved from either component alone. Polymer-based fiber composites have gained significant attention in various industries, including automotive, aerospace, marine, sporting goods, biomedical applications, electrical, protective equipment, energy storage, building, and civil engineering. Today, these composites are becoming increasingly attractive due to their enhanced lightness, affordability, durability, and versatility.

We are seeking papers that discuss the latest research or provide a summary of selected areas in the field of polymer-based fiber composites. The focus will be on the synthesis, manufacture, processing, characterization, properties, and applications of these materials. The aim of this Special Issue is to highlight recent research advancements in the field and demonstrate the broad range of applications for polymer-based fiber composites.

In this study, surface modification aimed to enhance the compatibility between a hydrophilic inorganic filler and polypropylene (PP) matrix using hydrophobic treatment. Lauric acid, butyl acrylate, and maleic anhydride were employed to modify the filler surface. After treatment, inorganic filler/PP composites were produced using melt-mixing and extrusion–injection molding processes. The study focused on investigating compatibility and migration behavior between the filler and matrix. The findings indicated that hydrophobic modification, specifically with butyl acrylate and maleic anhydride, improved migration issues in nano-whisker, while maintaining favorable mechanical properties even under accelerated thermal aging. However, excessive hydrophobicity induced by superhydrophobic treatment using lauric acid led to reduced compatibility with the matrix, compromising its effectiveness. Consequently, the study revealed the potential of surface modification to enhance interfacial properties and mitigate migration concerns in PP composites for automotive applications. Full article

Carbon aerogel is a promising material in various applications, such as water treatment, insulators, catalysts, and sensors, due to its porosity, low density, conductivity, and good chemical stability. In this study, an inexpensive carbon aerogel was prepared through lyophilization and post-pyrolysis using waste paper. However, carbon aerogel, in the form of short belts, is randomly entangled without a crosslinking agent and has weak mechanical properties, thus limiting its applications, which would otherwise be various. In this paper, a novel strategy is proposed to fabricate a PDMS-coated carbon aerogel (Aerogel@PDMS). Benefiting from microwave heating, precise PDMS coating onto the carbon frame was able to be carried out in a short amount of time. PDMS coating firmly tied the carbon microstructure, maintaining a unique aerogel property without blocking its porous structure. FE-SEM, RAMAN, XPS, and FT-IR were all used to confirm the surface change in PDMS coating. Compressible stability and water contact angle measurement showed that Aerogel@PDMS is a perspective organic solvent absorbent due to its good resilience and its hydrophobicity, and, as a result, its organic solvent absorption capacity and repeated absorption were evaluated, ultimately suggesting a promising material in oil clean-up and pollution remediation in water. Based on our experimental results, we identified elastic carbon aerogels provided by a novel coating technology. In the future, then, the developed carbon/PDMS composite can be examined as a promising option for various applications, such as environmental sensors, virus sensors, and wearable sensors.
