Abstract Polymethyl methacrylate (PMMA) is widely used in diverse applications such as protective components (e.g., automotive lamp covers and structural casings), optical devices, and biomedical products, owing to its lightweight nature and impact resistance. However, its surface hardness and wear resistance remain insufficient under prolonged exposure to abrasive environments. In this study, a multi-filler strategy with nano-silica (SiO₂), brominated lignin (Br-Lignin), and cellulose nanocrystals (CNCs) was employed to enhance PMMA tribological properties. SiO₂ provided localized reinforcement, Br-Lignin established stable network structures, and CNCs improved compactness, enabling strong synergistic effects. As a result, the composites achieved up to More >

Abstract With the global diabetes epidemic, diabetic foot ulcers (DFUs) have become a major health burden, affecting approximately 18 million people worldwide each year, and account for about 80% of diabetes-related amputations. Five-year mortality among DFU patients approaches 30%, which is comparable to that of many malignancies. Yet despite standard wound care, only about 30%–40% of chronic DFUs achieve complete healing within 12 weeks. This persistent failure shows that conventional dressings remain passive supports. They do not counteract underlying pathologies such as ischemia, prolonged inflammation, and infection. Recent advances in polymeric nanofiber scaffolds, particularly electrospun matrices,… More > Graphic Abstract

Abstract The crystallization behavior of polymers is significantly influenced by molecular chain length and the dispersion of varying chain lengths. The complexity of studying crystallization arises from the dispersity of polymer materials and the typically slow cooling rates. Recent advancements in fast cooling techniques have rendered the investigation of polymer crystallization at varying cooling rates an attractive area of research; however, a systematic quantitative framework for this process is still lacking. We employ a coarse-grained model for polyvinyl alcohol (CG-PVA) in molecular dynamics simulations to study the crystallization of linear polymers with varying chain lengths under… More >

Abstract Nowadays, the development of effective bioplastics aims to combine traditional plastics’ functionality with environmentally friendly properties. The most effective and durable modern bioplastics are made from the edible part of crops. This forces bioplastics to compete with food production because the crops that produce bioplastics can also be used for human nutrition. That is why the article’s main focus is on creating bioplastics using renewable, non-food raw materials (cellulose, lignin, etc.). Eco-friendly composites based on a renewable bioplastic blend of polybutylene adipate-co-terephthalate, corn starch, and poly(lactic acid) with reed and hemp waste as a filler.… More > Graphic Abstract

Abstract Composites made from biopolymers and natural fibers are gaining popularity as alternative sustainable structural materials. Biopolyesters including polylactic acid (PLA), polybutylene succinate (PBS), and polyhydroxyalkanoate (PHA), when mixed with natural fibers such as kenaf, hemp, and jute, provide an environmentally acceptable alternative to traditional fossil-based materials. This article examines current research on developments in the integration of biopolymers with natural fibers, with a focus on enhancing mechanical, thermal, and sustainability. Innovative approaches to surface treatment of natural fibers, such as biological and chemical treatments, have demonstrated enhanced adhesion with biopolymer matrices, increasing attributes such as… More > Graphic Abstract

Abstract Fiber-reinforced polymer (FRP) composites are renowned for their high mechanical strength, durability, and lightweight properties, making them integral to civil engineering, aerospace, and automotive manufacturing. Traditionally, the simulation and optimization of FRP materials have relied on finite element (FE) methods, which, while effective, often fall short in capturing the intricate behaviors of these composites under diverse conditions. Concrete examples in this regard involve modeling interfacial cracks, delaminations, or environmental effects that involve nonlinear phenomena. These degradation mechanisms exceed the capacity of classical FE models, as they are not detailed to the required level of detail.… More > Graphic Abstract

Abstract The selection of carbon sources and the biosynthesis of polyhydroxybutyrate (PHB) by the Azotobacter vinelandii N-15 strain using renewable raw materials were investigated. Among the tested substrates (starch, sucrose, molasses, bran), molasses as the carbon source yielded the highest PHB production. The maximum polymer yield (26% of dry biomass) was achieved at a molasses concentration of 40 g/L. PHB formation was confirmed via thin-layer chromatography, gas chromatography and Fourier transform infrared spectroscopy. Composite films based on PHB, polylactic acid (PLA), and their blends were fabricated using the solvent casting. The biodegradation of these films was studied More > Graphic Abstract

Abstract The development of actuators based on ionic polymers as soft robotics, artificial muscles, and sensors is currently considered one of the most urgent topics. They are lightweight materials, in addition to their high efficiency, and they can be controlled by a low power source. Nevertheless, the most popular ionic polymers are derived from fossil-based resources. Hence, it is now deemed crucial to produce these actuators using sustainable materials. In this review, the use of ionic polymeric materials as actuators is reviewed through the emphasis on their role in the domain of renewable materials. The review… More > Graphic Abstract

Abstract Porous organic polymers are remarkably versatile materials with porous and carefully designed structures. They complement traditional preservation methods by overcoming their limitations and significantly extending the shelf life of preserved products. Notably, porous hollow nanospheres (PHNs), with their unique hollow structures capable of adsorbing and releasing organic molecules, have garnered considerable attention in food preservation. However, most PHNs are challenging to synthesize in one step, and PHNs are usually in powder form, which makes it challenging to apply them directly. In this study, we successfully synthesized PHNs in one step using the Friedel–Crafts reaction. The… More > Graphic Abstract

Abstract This paper presents the development of a thermoplastic shape memory rubber that can be programmed at human body temperature for comfortable fitting applications. We hybridized commercially available thermoplastic rubber (TPR) used in the footwear industry with un-crosslinked polycaprolactone (PCL) to create two samples, namely TP6040 and TP7030. The shape memory behavior, elasticity, and thermo-mechanical response of these rubbers were systematically investigated. The experimental results demonstrated outstanding shape memory performance, with both samples achieving shape fixity ratios (R_f) and shape recovery ratios (R_r) exceeding 94%. TP6040 exhibited a fitting time of 80 s at body temperature (37°C), More >
