Special Issue Information

Dear Colleagues,

The growing demand for sustainable materials and environmentally responsible technologies has positioned polymer science as a key enabler for addressing pressing environmental challenges. This Special Issue focuses on recent advances in polymer-based materials and systems developed for environmental applications, with an emphasis on material design, structure–property relationships, and application-oriented performance.

Topics of interest include polymeric materials for water and air purification, environmental remediation, separation and membrane technologies, adsorption and catalytic processes, biodegradable and bio-based polymers, and recyclable polymer systems aimed at reducing environmental impact. Contributions on functional polymer composites, nanostructured polymers, and hybrid materials that enhance efficiency, selectivity, and durability in environmental processes are particularly welcome.

Manuscripts addressing polymer synthesis, modification, characterization, processing, and performance evaluation are encouraged, provided that a clear connection to environmental functionality or sustainability-driven outcomes is demonstrated. Studies bridging fundamental polymer science with practical environmental implementation are especially encouraged.

This Special Issue aims to provide a focused platform for disseminating high-quality research on innovative polymer materials that contribute to environmental protection, resource efficiency, and sustainable development.

Silica-supported zinc (II)–Schiff-base complexes were prepared through a simple and high-yield immobilization strategy and evaluated as heterogeneous catalysts for the ring-opening polymerization (ROP) of lactide. Silica gel and silica nanoparticles were employed as supports to assess the influence of support morphology and textural properties on catalytic performance. Comprehensive characterization by AAS, BET, SEM, and SEM–EDS confirmed effective anchoring of the Zn complexes, homogeneous metal distribution, and support-dependent textural modifications. The supported catalysts were active in the bulk ROP of racemic and enantiopure lactide, affording PLA with high conversions and moderate dispersities. Silica-gel-supported systems exhibited high and reproducible activity over a wide range of conditions, whereas catalysts supported on silica nanoparticles showed a stronger dependence on reaction time and ligand electronic effects, highlighting the key role of the support in modulating active site accessibility and chain growth. Microstructural and thermal analyses confirmed the formation of atactic PLA from rac-lactide and stereoregular PLLA from L-lactide. Overall, this study demonstrates that silica-supported zinc(II)–Schiff-base complexes constitute an effective and versatile heterogeneous platform for lactide ROP and underscore the importance of support properties in the rational design of sustainable catalysts for biodegradable polyester synthesis.
