Special Issue Information

Dear Colleagues,

The ever-growing demand for sustainable materials and the rising concerns over environmental pollution have steered global research efforts towards the development of advanced polymeric absorbent materials. This Special Issue, “Next-Generation Polymeric Absorbent Materials: Innovations in Sorption, Sustainability, and Micro/Nanoplastics Remediation”, aims to showcase recent breakthroughs in the design, synthesis, functionalization, and application of polymeric absorbents across various fields such as environmental remediation, biomedical engineering, industrial separation, and hygiene technologies.

Special attention will be paid to smart absorbent materials, bio-based and biodegradable polymers, nanocomposites, and hybrid systems that offer enhanced selectivity, capacity, and regeneration potential. Given the urgency of addressing micro- and nanoplastic pollution, we particularly welcome studies focusing on the selective capture, adsorption mechanisms, and long-term removal performance of these emerging pollutants. The issue also encourages contributions exploring advanced fabrication techniques (e.g., electrospinning, 3D/4D printing), mechanistic and rheological modeling of sorption processes, and real-world application case studies.

This Special Issue invites original research articles and comprehensive reviews that push the boundaries of current knowledge and bridge material innovation with sustainable impact.

Owing to their small size and surface hydrophobicity, microplastics (MPs) tend to act as vectors for various organic pollutants. However, in contrast to well-studied pollutants like polycyclic aromatic hydrocarbons, the sorption of benzene-series compounds on MPs has been seldom studied. To investigate the sorption process, the isotherms were determined for the sorption of three benzene-series sorbates by three polymers with different physicochemical properties. The linear sorption isotherms observed for PE indicate that sorbate uptake was dominated by partitioning into the bulk polymer. In contrast, the non-linear isotherms of PP and PVC imply that adsorption onto surfaces was the dominant mechanism. Sorption capacity of m-xylene and ethylbenzene increased in the following order: polyvinyl chloride (PVC) < polyethylene (PE) < polypropylene (PP). This order does not reflect the polarity or the crystallinity of the investigated MPs, suggesting the influence of additional factors (e.g., glass transition temperature, specific surface area) on the sorption of BTEX by MPs. In addition, the particle size and morphology of MPs are also factors affecting sorption capacity. The strong correlation between the sorption coefficients and sorbate hydrophobicity indicates that the hydrophobic interactions played a crucial role. Meanwhile, specific sorbate properties, such as electronic structure and molecular polarizability, are also significant factors that affect the sorption behaviors. Full article
