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 >

Abstract Polyether ether ketone (PEEK)-based continuous glass fiber reinforced thermoplastic composite offers advantages such as high strength, electrical insulation, and heat insulation. Parts manufactured using this composite and 3D printing have promising applications in aerospace, automobile, rail transit, etc. In this paper, a high-temperature melt impregnation method was used to successfully prepare the 3D printing prepreg filaments of the aforementioned composite. In the FDM 3D printing equipment, a nozzle of high thermal conductivity and wear-resistant copper alloy and a PEEK-based carbon fiber thermoplastic composite build plate with uniform temperature control were innovatively introduced to effectively improve… More >

Abstract The rapid development of urban rail transit has posed increasing construction and operational challenges for metro tunnels, often leading to structural damage. Grouting technology using cement-based materials is widely applied to address issues such as seepage, leakage, and alignment correction in shield tunnels. This study investigates the additional stress induced by grouting in silty soil layers, using cement-based grouts with different water-to-cement ratios and polyurethane-modified cement-based materials. Results show that additional stress decreases with depth and is more influenced by horizontal distance from the grouting point. In staged grouting, the first injection phase contributes about More >

Abstract Vibration isolation is vital in engineering machinery, as it not only seriously affects the service life of machine components but also reduces the operating efficiency. Recently, metamaterials have been proposed for customized vibration-isolation needs through various functional designs. As a synthetic material, polymer materials have the advantages of good elasticity, low density, high specific strength, good corrosion resistance and easy processing, making it an ideal raw material for vibration-isolation metamaterials. At the same time, the rapid development of additive manufacturing (AM) provides a feasible method for preparing polymeric vibration-isolation metamaterials with complex structures. In this More >

Abstract A Shape Memory Polymer Composite (SMPC) is developed by reinforcing an epoxy-based polymer with randomly oriented short glass fibers. Diverging from previous research, which primarily focused on the hot programming of short glass fiber-based SMPCs, this work explores the potential for programming below the glass transition temperature (Tg) for epoxy-based SMPCs. To mitigate the inherent brittleness of the SMPC during deformation, a linear polymer is incorporated, and a temperature between room temperature and Tg is chosen as the deformation temperature to study the shape memory properties. The findings demonstrate an enhancement in shape fixity and More >

Abstract PU, or polyurethane, features a repeating urethane group (-NH-COO-) in its molecular structure. Traditionally, PUs are synthesized from isocyanate and polyol compounds derived from fossil resources through polymerization reactions. The depletion of fossil fuels and the increasing climate problems call for the expansion of more renewable sources of chemicals, such as modern biomass. However, the conversion of biomass into chemicals is challenging due to the inherent molecular complexity of its composition. In recent years, advances in green chemistry have led researchers to focus on developing bio-based polyurethanes by sourcing polyols, isocyanates, and chain extender precursors More >

Abstract The food industry prioritizes food safety throughout the entire production process. This involves closely monitoring and evaluating all potential sources of biological or chemical contamination, starting from entering raw materials into the production chain and continuing to the final product. Biofilms on food surfaces or containers can harbor dangerous pathogens, such as Listeria monocytogenes. Therefore, it is essential to continuously manage microbial contamination on food contact surfaces to prevent foodborne infections. Recently, there has been increasing interest in using nanomaterials as surface coatings with antimicrobial properties in the food industry, especially since traditional disinfectants or antibiotics… More >

Abstract The global scarcity of clean water is an escalating issue due to climate change, population growth, and pollution. Traditional water purification technologies, while effective, often require significant energy input and complex infrastructure, limiting their accessibility. This review explores the use of conjugated polymer hydrogels as a promising solution for solar water purification. Conjugated polymer hydrogels offer unique advantages, including high photothermal conversion efficiency, effective heat management, and rapid water transport, which are crucial for efficient solar-driven water evaporation. By leveraging the properties of these hydrogels, it is possible to significantly reduce the energy required for More >
