Special Issue Information

Dear Colleagues,

The demand for sustainable polymer applications has surged across various industries, driven by the global commitment to addressing environmental challenges and fostering innovation. This Special Issue of Polymers focuses on cutting-edge research and advancements in polymer science, particularly in the fields of sustainable food packaging, wastewater treatment, predictive microbiology, and computational approaches to polymer synthesis and catalysis.

We welcome contributions in the form of original research articles, reviews, and case studies that explore the following:

  • Development and characterisation of biodegradable or recyclable polymers for eco-friendly food packaging solutions;
  • Applications of advanced polymer materials in the purification of industrial and domestic wastewater;
  • Integration of polymers in predictive microbiology to enhance food safety and shelf-life monitoring;
  • Computational modelling and simulation studies addressing polymer design, synthesis, and catalytic behaviour.

This Special Issue aims to bridge the gap between fundamental research and practical applications, fostering interdisciplinary collaboration to promote sustainable and innovative solutions.

Join us in shaping the future of polymers for a sustainable world.

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.

Chlorella vulgaris is a microalga with antioxidant and antimicrobial capacity that contains high levels of starch and proteins, essential for producing biodegradable packaging. This study aims to develop and characterize biofilms from soft wheat flour (SWF) and durum wheat flour (DWF) with yellow and white Chlorella vulgaris. The films were made using the compression molding method and characterized according to their physical, mechanical, and structural properties. The results indicated that yellow Chlorella films increase thickness and gloss and reduce water vapor permeability, which benefits applications requiring moisture retention. On the other hand, white Chlorella increases opacity and color saturation, making it suitable for less transparent packaging. Films with durum wheat and microalgae are stiffer and less elastic, while formulations with soft wheat and without microalgae are flexible. The surface texture is rougher in films with yellow Chlorella and more homogeneous in white Chlorella. These results suggest that Chlorella vulgaris allows biodegradable films to be tailored for specific applications in sustainable packaging. Full article
