Special Issue Information

Dear Colleagues,

Welcome to this Special Issue focusing on the latest developments on the topic of epoxy-based materials. Epoxy is a type of polymer material widely used in various industries due to its good mechanical properties and processability. Epoxies are employed in different applications such as adhesive bonding, circuits, coatings, fibre-reinforced polymers, encapsulation, paints, and others.

This Special Issue aims to include fundamental research regarding polymer synthesis and characterisation, curing, and particle modifications for improved properties; experimental characterisation; novel techniques for modelling and simulation; multi-scale simulation; high-performance applications with composite materials; polymeric fibres; and sustainability. Additionally, it will also consider current challenges such as bio-based epoxy synthesis and extreme applications including cryogenic operating conditions for adhesives or for fibre-reinforced polymers.

I would like to invite you to contribute to this Special Issue, “Advances in Epoxy-Based Materials”, at your convenience.

Dr. Paulo Teixeira Goncalves
Guest Editor

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 250 words) can be sent to the Editorial Office for assessment.

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.

For the purpose of reducing environmental and health risks in the production of fibre-reinforced polymers, biomolecules are increasingly examined as alternative resources. For example, amino acids can serve as curing agents for epoxy resins. However, their particular appearance and possible reactions differ from those of conventional hardeners. To find a performance-optimised mixing ratio, it is relevant to know how deviations in the mixing ratio affect the reactions that take place and the resulting thermo-mechanical properties. Consequently, in this study, eleven mixing ratios of L-arginine-cured DGEBA without a catalyst or accelerator were investigated optically, thermo-mechanically, and via FTIR analysis. Based on the theoretical stoichiometric ratio, a wide range of good thermo-mechanical properties between stoichiometric ratios of R = 0.8 and R = 1.0 could be determined. However, this study led to an extension of a possible reaction mechanism for the curing of epoxides with amino acids, particularly L-arginine, postulating the thermo-induced deprotonation of α-NH3+ groups, etherification as part of successful crosslinking, and the unfavourable reactivity of the guanidium group in the case of L-arginine, shifting the optimal to slightly sub-stoichiometric configurations.
