Special Issue Information

Dear Colleagues,

Until the 1980s, polymers were mainly considered the basis for the production of structural materials with unique physical and mechanical properties that could not be achieved with low-molecular-weight chemical compounds. In the last two decades of the XX century, polymers began to be used as functional materials in medicine, lighting, electrical engineering, electronics, energy, etc. At the turn of the century XX–XXI, the concept of “smart materials” was formulated, describing materials that can reversibly change their behavior due to external conditions such as temperature and humidity change or when exposed to mechanical, electrical, magnetic, and other fields. Currently, functional and "smart" polymeric materials are used in almost all areas of technology. In addition, many new polymeric substances with excellent thermal, mechanical, chemical, and electrical properties have been synthesized. Functional polymers include electrically conductive polymer materials, liquid crystal polymers, polymer gels, shape memory polymers, and so on. The strategy for the development of functional polymers includes the design of organic molecules; the development of formulae to control complex reactions that allow the molecular structures of organic compounds to be freely modified; the development of directed synthesis methods; the modification of polymers and materials based on a specific structure (including nanostructure) and morphology. The aim of this Special Issue is to comprehensively present new advances in the synthesis and processing of functional polymer materials.

Abstract
This study investigates the preparation of electrospun recycled polyethylene terephthalate (rPET) coated with chitosan (CS) and evaluates their antibiofilm properties and in vivo response. rPET scaffolds were first fabricated via electrospinning at different flow rates (10, 7.5, 5 and 2.5 mL/h) and subsequently [...] Read more.
This study investigates the preparation of electrospun recycled polyethylene terephthalate (rPET) coated with chitosan (CS) and evaluates their antibiofilm properties and in vivo response. rPET scaffolds were first fabricated via electrospinning at different flow rates (10, 7.5, 5 and 2.5 mL/h) and subsequently coated with chitosan. Scanning electron microscopy (SEM) revealed that fiber morphology varied with electrospinning parameters, influencing microbial adhesion. Antimicrobial tests demonstrated that rPET@CS significantly inhibited Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans biofilm formation compared to control and uncoated rPET surfaces. Subcutaneous implantation of rPET@CS scaffolds induced a transient inflammatory response, with macrophage recruitment and collagen deposition supporting tissue integration. These findings highlight the potential of rPET@CS scaffolds as sustainable antimicrobial biomaterials for applications in infection-resistant coatings and biomedical implants. Full article

Functional polymeric materials play a critical role in optimizing flocculation and sedimentation processes in mining tailings, where complex interactions with mineral surfaces govern polymer performance. This study examines the structure–performance relationship, which describes how the internal structure of aggregates (e.g., compactness, porosity and fractal dimension) influences sedimentation behavior, specifically for anionic polyacrylamide (SNF 704) in kaolin-quartz-pyrite suspensions at a pH of 10.5. Using focused beam reflectance measurement (FBRM) and static sedimentation tests, we demonstrate that pyrite exhibits the highest flocculant adsorption capacity, inducing a train-like polymer conformation on its surface. This reduces the formation of effective polymeric bridges, resulting in less compact and more porous aggregates that negatively impact sedimentation rates. Increasing the flocculant dosage improves the capture of fine particles; however, at high pyrite concentrations, rapid saturation of adsorption sites limits flocculation efficiency. Additionally, the fractal dimension of the aggregates decreases with increasing pyrite content, revealing more open structures that hinder consolidation. These findings underscore the importance of optimizing polymer dosage and tailoring flocculant design to the mineralogical composition, thereby enhancing water recovery and sustainability in mining operations. This study highlights the role of structure–property relationships in polymeric flocculants and their potential for next-generation tailings management solutions. Full article

Starch is one of the most abundant polysaccharides in nature and has a high potential for application in several fields, including effluent treatment as an adsorbent. Starch has a unique structure, with zones of different crystallinity and a glycosidic structure containing hydroxyl groups. This configuration allows a wide range of interactions with pollutants of different degrees of hydrophilicity, which includes from hydrogen bonding to hydrophobic interactions. This review article aims to survey the use of starch in the synthesis of diverse adsorbents, in forms from nanoparticles to blends, and evaluates their performance in terms of amount of pollutant adsorbed and removal efficiency. A critical analysis of the materials developed, and the results obtained is also presented. Finally, the review provides an outlook on how this polysaccharide can be used more effectively and efficiently in remediation efforts in the near future. Full article
