Progress and Prospects of Polymer/One-Dimensional Nanoclay Superabsorbent Composites

Polymers, Journal Year: 2025, Volume and Issue: 17(5), P. 669 - 669

Published: Feb. 28, 2025

Superabsorbent materials (SAMs), featuring a three-dimensional (3D) hydrophilic polymer network, can absorb and retain water up to thousands of times their own weight, even under pressure. This makes them indispensable in various fields, including hygiene products agriculture. The absorption capacity SAMs is influenced by the presence groups swellable network structure. To optimize performance, one must adjust types concentrations functional groups. Additionally, changes density regularity are necessary. Significant performance improvements limited inherent challenges modifying chains or networks. enhance researchers focus on manipulating components structure network. Effective retention requires fully expand while maintaining its strength. Incorporating nanoparticles, especially one-dimensional (1D) nanoclays, minimizes chain entanglement prevents collapse during drying. approach effectively addresses above challenges. Upon swelling, these nanoparticles improve hydrogen bonding within significantly boosting SAMs. Nanoclays abundant natural silicates found nanostructures like nanorods, nanofibers, nanotubes. These nanoclays contain reactive silanol that form strong bonds with chains. aids formation reduces costs. Advances synthesis structural control have facilitated development versatile 1D nanoclay-based paper reviews structure, characteristics, applications such proposes future research directions aimed at developing higher-performance clay-based

Adsorption of Bisphenol A from Water Using Chitosan-Based Gels

Gels, Journal Year: 2025, Volume and Issue: 11(3), P. 180 - 180

Published: March 5, 2025

The comonomer bisphenol A (BPA) finds applications in the plastics industry, where it is used production of polycarbonates, plastics, PVC, thermal paper, epoxy and vinyl ester resins, polyurethane. water, with which many these materials come into contact, one main sources human exposure to BPA. When ingested or touched, BPA can damage organs, disrupt endocrine immune systems, generate inflammatory responses, be involved genotoxic processes. Therefore, need develop effective techniques for removing from aqueous environments imperative. This paper provides a comprehensive review regarding removal focusing on performance adsorption mechanisms various adsorbents based chitosan composites. chemical physical factors, kinetics models governing process are also examined. outlines that, despite considerable progress absorption using gels, further research necessary assess efficacy treating real wastewater large-scale manufacture.
