Special Issue Information

Dear Colleagues,

Polymer materials with adsorption properties are an important branch of polymers and play crucial roles in a huge number of research areas: wastewater treatment, soil remediation, environmental optimization, efficient separation of small organic molecules and green catalysis, etc. For these reasons, research on polymer materials with adsorption properties has been a hot topic in recent years, although there are still some difficulties in their application. 

This Special Issue focuses on the latest research on polymer materials with adsorption properties, covering all aspects of porous organic polymer and applications. Potential topics include but are not limited to the following: 

  • Ion exchange and chelating resins;
  • Multifunctional polymer adsorbent;
  • Porous organic polymer;
  • Graft and cross-linkable polymer with adsorption property;
  • Polymer with special structure and superior/improved adsorption properties;
  • Other polymer-derived adsorbents;
  • Modification of polymer adsorbent;
  • Method for evaluating adsorption property of polymer material;
  • Theory and simulation of polymeric adsorbent.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Microplastics and per- and polyfluoroalkyl substances (PFAS) both represent persistent groups of environmental contaminants that have been associated with human health risks. Microcystin toxins are produced and stored in the cells of cyanobacteria and may be released into sources of drinking water. Recent concerns have emerged regarding the ability of microplastics to adsorb a range of organic contaminants, including PFAS and microcystins. This study examined the adsorption of two long-chain and two short-chain PFAS, as well as two common microcystins, by both virgin and weathered microplastics in freshwater. Natural weathering of microplastic surfaces may decrease adsorption by introducing hydrophilic oxygen-containing functional groups. Up to 50% adsorption of perfluorooctanesulfonic acid (PFOS) was observed for virgin PVC compared to 38% for weathered PVC. In contrast, adsorption capacities for microcystins by virgin LDPE were approximately 5.0 µg/g whereas no adsorption was observed following weathering. These results suggest that adsorption is driven by specific polymer types and dominated by hydrophobic interactions. This is the first known study to quantify PFAS and microcystins adsorption when considering environmentally relevant concentrations as well as weathered microplastics. Full article
