Special Issue Information

Dear Colleagues,

Polymers have largely replaced the use of traditional materials such as metal, wood and glass, providing basic properties at lower costs. However, for medical, food or agriculture-related applications, particular qualities are required, and this involves the use of expensive or very sensitive components for which the bulk approach is not suitable. This can be overcome by providing bioactivity only on the surface of the materials, in the form of coatings. The physical advantages of the support material can be combined in this way with the specific properties of the coating.

This Special Issue of Polymers welcomes the submission of original research papers and review articles that address bioactive coatings with biomedical, food or agriculture-related applications. This includes the (i) application of coating materials with intrinsic bioactivity; (ii) the use of coating matrices for the immobilization of bioactive compounds; (iii) the stabilization/protection and migration of bioactive properties into/from the coatings; (iv) interactions in the bioactive agent/matrix/support system; (v) various methods of structuring the coatings (e.g., xerogels, electrospinning); and (vi) the economical and sustainable aspects of bioactive materials developed from renewable resources.

The increasing accumulation of polymer waste presents a significant environmental challenge and a critical opportunity for the development of circular and sustainable membranes. The answer to this complex topic requires an integral approach covering different aspects of the problem. This paper, therefore, explores innovative approaches for the chemical recycling of polymer waste into value-added products, with a specific emphasis on the production of advanced biopolymer membranes. By converting discarded materials into functional polymers through depolymerization and chemical modification processes, new pathways are emerging for the fabrication of high-performance membranes used in filtration, biomedical applications, and energy systems. Among these, electrospinning has gained prominence as a versatile and scalable technique for producing nanostructured membranes with tailored properties. As a key case study presented, the focus was on the optimization of electrospinning parameters, including solvents, polymer concentration, voltage, and flow rate, for the investigation of membranes derived from recycled materials to achieve net-zero technology. Moreover, the environmental benefits of this approach are discussed within a zero-waste and net-zero carbon framework, emphasizing the integration of life cycle assessment to evaluate sustainability metrics. This paper underscores the potential of polymer waste as a feedstock for circular membrane technologies and provides a roadmap for future innovations in waste-to-resource strategies. The results of the demonstrated case example clearly demonstrate how the effects of processing conditions on the production of fine-tuned biodegradable membranes with controlled porosity influenced membrane properties, including mechanical strength and surface functionality, for the desired suppression of the coffee-ring effect.
