Special Issue Information

Dear Colleagues,

Fossil-fuel-based synthetic polymers have incredible properties; however, they take decades to degrade in the natural environment. Therefore, renewable-resource-based biopolymers that are sustainable and potentially degradable are gaining attention worldwide. Although substantial progress has been made in this field in the last couple of decades, limited success has been achieved in the substitution of fossil-fuel-based polymers with bio-based polymers.

Bio-based polymers may be classified into three main categories: polymers directly extracted from biomass; polymers produced by microorganisms or genetically modified bacteria; and polymers synthesized using bio-based monomers. So far, the focus has mainly been on the extraction and utilization of extracted polymers from biomass such as cellulose, starch, and protein, with limited works reported the synthesis of monomers and biopolymers from renewables. There is a great opportunity to produce renewable polymers from biomass, but several challenges that need to be addressed here regarding the synthesis and properties of such polymers.

This Special Issue, following on from the first edition, is focused on challenges and opportunities in the synthesis of bio-based monomers.

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.

With the aim of meeting the growing demand for safe food, intelligent packaging has emerged, which monitors the conditions of the food and informs the consumer about its quality directly at the time of purchase. Among intelligent packaging options, colorimetric indicator films, which change color in response to changes in the food, such as the release of volatile compounds, have been widely studied. Among them, pH indicator films composed of dyes sensitive to small variations in the pH value of the food surface have received greater attention in recent years. Anthocyanins, which are natural pigments, have stood out as one of the most commonly used sources of dyes in the production of these indicator films. In this context, the present review aims to present an updated overview of research employing anthocyanins in indicator films, including their stability under different storage conditions, the influence of different polymers used in their production, and alternative techniques for maintaining stability.
