Special Issue Information

Dear Colleagues,

Flame-retardant polymers have already been popularly used in buildings, factories, vehicles, and other places. In past decades, various flame-retardant additives and other technologies have been invented and utilized to reduce the flammability of polymers. In the field of fire safety engineering, both the design of new fire test standards and burning mechanism modeling are necessary and important for developing better flame-retardant polymers. 

The detailed ignition criterion and flame spread mechanism is one of the most challenging topics for new flame-retardant polymers. This Special Issue will publish new works about the pyrolysis, ignition, burning, and flame spread of flame-retardant polymers, including new findings based on standard or non-standard fire test devices, detailed heat and mass transfer mechanism of flame-retardant polymers in a fire scenario, and other new works about their fire safety analyses.

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.

The traditional aqueous flame-retardant coating faces the problem of slow solvent evaporation rate in the preparation process. It is an urgent problem to ensure that the function of the membrane is not destroyed while accelerating the solvent volatilization. Herein, we fabricated films on the metal substrate surface by a totally novel method: demulsification-induced fast solidification to rapidly obtain the flame-retardant coating. The environmentally friendly flame retardants aluminum hydroxide and red phosphorus were mixed with the commercial water-based polyurethane 906 emulsion to explore the optimal mixing ratio, where the adhesion of the flame-retardant reached the Grade 3 standard, the sample remained intact after the 100 cm drop hammer test and the limiting oxygen index value reached 30.4%. In addition, compared with the traditional process, this method, with the advantages of rapidly drying, environmentally friendly, uniformly prepared coatings on the surface of any shape substrates, as well as accurate and controllable coating thickness, can be widely applied in the flame-retardant field.
