The cover image by Dr. Noorullah Baig shows how metal-organic copolymers containing iron(II) clathrochelated with various arylamines were synthesized via a palladium-catalyzed Sonogashira crosscoupling reaction. The copolymers reveal ultrafast dye adsorption efficiencies up to 100% and exhibit maximum adsorption capacity (q_m) for Methylene Blue and Congo Red of 146.63 mg g⁻¹ and 787.40 mg g⁻¹, respectively. The metal-organic polymers demonstrate several advantages, namely, their versatile synthesis, low cost, superior thermal stability, excellent adsorption capacity, and high surface area, which qualify them as prominent adsorbents for water purification applications.

The synthesis of four copolymer networks based on iron(II) clathrochelate derivative and several arylamines is described. Target copolymers reveal microporous properties with surface areas up to 411 m²g⁻¹. They demonstrate efficient adsorption of various organic dyes from aqueous media making them promising candidates for environmental remediation.

Organosilicon nanocapsules encapsulating the antifouling agent DCOIT were prepared based on the self-catalytic sol–gel reaction between methyl trimethoxysilane (MTMS) and 3-aminopropyl trimethoxysilane (APS). With the encapsulation efficiency as the evaluation index, the response surface method was used to optimize the preparation process. The results indicate that the obtained nanocapsules would have great potential for application in antifouling coatings, which are sufficient to cope with the challenges brought by marine environments.

Due to the first synthesis of degradable CS/SA plastic materials in organic systems, the crosslinked CS-SA blends have better hydrophobicity, mechanical strength, permeability, stability, and antibacterial properties, extending the storage time of grapes to more than 14 days, and greatly meet the needs of food plastic packaging.

A reduction-sensitive folate-dextran-diethyldithiocarbamate (DDTC) prodrug conjugate can self-assemble into nanoprodrugs for tumor cell targeting and robust tumor chemotherapy.

Vapour-phase reaction of CNC aerogel with MTS followed by its adsorption of paraffin and the desorption

Thiol-ene thermoset and composite resins developed for hard tissue repair are adapted for SLA 3D printing through the addition of either diluents, free radical inhibitors, or micro- and nano-sized hydroxyapatite. The resulting printed materials display excellent biological profiles, while their mechanical properties exceed the thiol-ene printed systems in the literature.

A facile and green method for surface functionalization of cellulose nanofiber (CNF) by mussel-like oxidative polymerization of tannic acid and ethanediamine is reported. The modified CNF was then used as filler for constructing multifunctional polyvinylalcohol composites with comprehensively improved properties.

Herein, the morphology, physicochemical structure, chemical composition, and thermostability of Wheat straw (WS) and lignocellulose nanofibrils (LCNFs) were systematically investigated, aiming to reveal the impact of screw extrusion and ball milling during the process of LCNF preparation. This work could not only offer theoretical guidance on the preparation of LCNFs by mechanical pretreatments but also expand the high-value application of agricultural residues in polymer composites.

This paper provides a simple, economical, and environmentally benign fabrication process for light-scattering PC with excellent flame-retardant performance. During processing, the strong hydrogen bond interaction between PSi and SAN enabled the in-situ formation of flame-retardant scatterers SAN-PSi, which allowed us to prepare light-scattering PC with excellent flame-retardant performance in the one-step melt blending process.

Acrylate monomers with different alkyl chain structure were applied to prepare polymer dispersed liquid crystals films and the electro-optical performance and microstructure were compared. By balancing the alkyl chain length, branched chains and isomeric structure, low driving voltage and high contrast ratio can be achieved. The transparent and opaque states can work effectively to show or block the background picture.

A novel bis-epoxy end functionalized polyisoprene (BETPI) macromonomers are prepared by living anionic polymerization and high-pressure RAFT polymerization. The BETPI with 600–1000 Da of molecular weight and over 75% of epoxy end capping rate, which can be further utilized as highly reactive liquid macromonomers in rubber coupling agents, vitrimer materials, and other fields.

In the present work, we carried out the synthesis of renewable low viscosity polyester-polyols for thermoplastic polyurethane applications. Our proposed low viscosity polyester-polyols were found to be attractive candidates for industrial large-scale applications, enabling the synthesis of thermoplastic polyurethanes at a lower temperatures. These TPUs showed good mechanical properties and excellent biodegradation under compost conditions.

Environmentally friendly intumescent flame retardant (IFR) based poly (butylene succinate) (PBS) composites are prepared using water hyacinth fiber (WHF) and ammonium polyphosphate (APP) as IFR, with glycidyl methacrylate grafted poly (butylene succinate) (PBS-g-GMA) as a compatibilizer. The enhanced mechanical properties and flame retardancy of WHF/APP/PBS composites will promote the development of biodegradable flame-retardant polymer composites for engineering applications.
