Special Issue Information

Dear Colleagues,

Polymers and materials made of them are commonly used in almost all fields of life. Despite numerous ecological restrictions and considerable amounts of process and post-consumer waste that is often difficult to recycle, the production and consumption of polymer materials have systematically increased around the world. The problem of the reduced flammability of plastic materials products has special importance, not only from economic reasons but also the protection of human life. During the combustion of plastics, a considerable amount toxic gaseous and smoke is formed.

Currently, smoke is primarily treated as a carrier of organic and carcinogenic compounds from the PCDDs/F and PAH groups.

Developing flame-retardant materials and understanding the phenomena that take place during the combustion of plastic materials very often require close collaboration between several fields of scientific expertise, such as macromolecular and physics chemistry, physics, mass and heat transfer, and so on.

This Special Issue, entitled “Thermal Stability and Fire Performance of Polymeric Materials”, aims to provide an excellent opportunity to publish the latest advances in these research fields. Full papers, review articles, and communications are all welcome.

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. Materials 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 2600 CHF (Swiss Francs).

This study focuses on examining the influence of bast fibers on the flammability and thermal properties of the polylactide matrix (PLA). For this purpose, Urtica dioica and Vitis vinifera fibers were subjected to two types of modifications: mercerization in NaOH solution (M1 route) and encapsulation in an organic PLA solution (M2 route). In a further step, PLA composites containing 5, 10, and 15 wt% of unmodified and chemically treated fibers were obtained. The results of the tests show that only biocomposites containing mercerized fibers had a nearly 20% reduced flammability compared to that of PLA. Moreover, the biofiller obtained in this way belongs to the group of flame retardants that generate char residue during combustion, which was also confirmed by TGA tests. The M2 modification route allowed to achieve higher mass viscosity than the addition of unmodified and M1-modified fibers. The reason is that fibers additionally encapsulated in a polymer layer impede the mobility of the chain segments. The inferior homogenization of the M2-modified fibers in the PLA matrix translated into a longer combustion time and only a 15% reduction in flammability. Full article
