Special Issue Information

Dear Colleagues,

Smart, intelligent, or responsive biopolymers are materials derived from biological sources that exhibit responsive behaviors to external stimuli such as temperature, pH, light, or magnetic fields. These materials have gained significant attention due to their potential applications in various industries, offering sustainable and innovative solutions. Biopolymers are typically sourced from renewable resources like plants, algae, and microorganisms, making them a more sustainable option. Their biodegradability ensures they break down naturally, reducing the environmental footprint and addressing the growing concern over plastic waste. Despite their advantages, their adoption faces several challenges. The production cost is often higher than that of conventional polymers, and there are still technical problems in scaling up manufacturing processes. Furthermore, novel applications and materials are still required, as well as advances in current known smart biopolymers. Smart biopolymers represent a promising frontier in material science, potentially transforming various industries through their responsive and sustainable properties.

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.

This study explores the development of biodegradable starch-based films treated with dielectric barrier discharge (DBD) plasma and incorporated with acerola residue and grape pomace extracts. The primary aim was to enhance the films’ physicochemical properties and introduce pH-sensing capabilities. Plasma treatment at 200 Hz for 20 min modified the films’ amylose content (by 13.2%), solubility (by 13.3%), contact angle (by 12.7%), moisture content (by 14.2%), and surface morphology. The addition of the extracts changed the short-range ordered structure parameters of the films (by 111.4%), solubility (by 11.1%), moisture content (by 18.4%), and water vapor permeability (by 6.1%). The films with acerola residue and grape pomace extracts exhibited good colorimetric responses for pH indication. The films with acerola residue extract tended to intensify the yellowish color, while those with grape pomace extract showed more significant color changes varying from purple to green. Integrating natural pigments like anthocyanins from grape pomace and carotenoids from acerola improved the films’ functional properties and provided a visual indication of food freshness through pH changes.
