Special Issue Information

Dear Colleagues,

In light of the 30th anniversary of Molecules, we are pleased to announce the launch of a Special Issue titled "30th Anniversary of Molecules—Recent Developments in Biobased Polymers". Over the years, Molecules has grown to become a vital platform for the dissemination of cutting-edge scientific research, and this milestone would not have been possible without the unwavering support of our authors, peer reviewers, readers, and editorial team. We sincerely thank all those who have contributed to the journal’s success.

This Special Issue aims to highlight the latest developments and innovations in the field of biobased polymers, a topic of growing significance in sustainable science and technology. We invite the submission of full-length research articles and high-quality review papers focusing on the following areas:

  • The synthesis, characterization, and properties of novel biobased polymers.
  • Innovative approaches to functionalizing or processing biobased materials.
  • The applications of biobased polymers in various fields, including packaging, medicine, and environmental science.
  • Advances in the biodegradability, recyclability, and lifecycle analysis of biobased materials.
  • The development and validation of analytical techniques for studying biobased polymers.

We particularly welcome contributions that demonstrate the application of advanced methodologies, including green chemistry principles or analytical techniques, to real-world challenges in this domain.

Join us in celebrating this milestone by sharing your groundbreaking work and helping us chart a path toward a more sustainable future through the advancement of biobased polymer research.

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. Molecules 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.

In the food packaging industry, significant efforts have been dedicated to addressing the pressing market demand for environmentally friendly and sustainable products. Biocomposite films based on compostable and biobased polymers represent a sustainable alternative to conventional packaging materials, offering biodegradability and enhanced functional properties. Additionally, there is growing interest in utilizing waste materials from agriculture and the food industry. This study focuses on the development of multifunctional eco-sustainable biocomposite films by combining poly(lactic acid) (PLA) as a biopolymeric matrix and extracts derived from coffee silverskin (CS), a significant agro-industrial waste byproduct of the coffee roasting process. Extracts of coffee silverskin were obtained via extraction with several solvents. Several properties of the prepared biocomposites were measured using techniques such as scanning electron microscopy (SEM), infrared spectroscopy (FTIR, ATR), differential scanning calorimetry (DSC), and oxygen and water vapor permeability, together with mechanical and physico-chemical characterization and measurements of water content, film solubility, and degree of swelling. The results demonstrate that optimized formulations of PLA/CS biocomposite films exhibit enhanced oxygen barrier properties, reduced permeability, and significant antioxidant activity. These findings underscore the potential for agro-waste valorization in creating eco-friendly food packaging solutions. Full article
