Special Issue Information

Dear Colleagues,

Following the success of the Special Issue of Polymers, "Epoxy Resins and Epoxy-Resin-Based Polymer Materials", https://www.mdpi.com/journal/polymers/special_issues/epoxy_resin_polymer_materials, we are delighted to reopen this Special Issue, now entitled "Epoxy Resins and Epoxy-Resins-Based Polymer Materials II".

Epoxy resins have been known for almost 100 years. Owing to their superior mechanical properties and chemical resistance, they have been widely used in many demanding application fields, such as automotive, aeronautics, construction building, and electronics, where they are used as coatings, adhesives, and structural materials. Notwithstanding these successes, new research shows new application possibilities for epoxy resins and epoxy-based polymers, i.e., optoelectronics, telecommunications, energy storage, medical applications, membranes, and so on. The general aim of this Special Issue on “Epoxy Resins and Epoxy-Resins-Based Polymer Materials II” is to provide insights into current research and developments in the field of epoxy resins, epoxy polymers (new monomers, innovative formulations and processing, engineering properties), and new materials based on epoxy resins.

Herein the synthesis, characterization, and study of spectroscopic, thermal, and thermo-mechanical properties of polymeric composites are presented. The composites were obtained in special molds (8 × 10 cm) based on the commercially available epoxy resin Epidian® 601 cross-linked by 10% w/w triethylenetetramine (TETA). To improve the thermal and mechanical properties of the synthetic epoxy resins, natural fillers in the form of minerals from the silicate cluster kaolinite (KA) or clinoptilolite (CL) were added to the composites. The structures of the materials obtained were confirmed by attenuated total reflectance-Fourier transform infrared spectroscopy (ATR/FTIR). The thermal properties of the resins were investigated by differential scanning calorimetry (DSC) and dynamic-mechanical analysis (DMA) in an inert atmosphere. The hardness of the crosslinked products was determined using the Shore D method. Moreover, strength tests were performed on the 3PB (three-point bending) specimen, with the analysis of tensile strains conducted using the Digital Image Correlation (DIC) technique. Full article

In this paper, epoxy-acrylate structural adhesives tapes (SATs) were obtained from Bisphenol A-based liquid epoxy resin and epoxy acrylic resins (EARs). A new method of EARs preparation, i.e., the free radical bulk photopolymerization process (FRBP), was studied in detail. The influence of methacrylic monomers (methyl methacrylate, ethyl methacrylate, butyl methacrylate, lauryl methacrylate, (2-acetoacetoxy)ethyl methacrylate) and vinyl monomers (N-vinylpyrrolidone and styrene) on the FRBP process of base monomers (i.e., butyl acrylate, glycidyl methacrylate and 2-hydroxyethyl acrylate) was investigated. The kinetics of photopolymerization process was monitored by photo-differential scanning calorimetry method. The properties of the obtained EARs (viscosity and average molecular weights), as well as monomers conversion using 1H NMR, were determined. It was revealed that styrene significantly decreases the photopolymerization rate and increases the final monomers conversion (+27%). However, the resulting tetrapolymers BA-co-GMA-co-HEA-co-STY have low molecular weights and low polydispersity (2.2). Methacrylate monomers with shorter aliphatic chains (<C4) also decrease the rate of photopolymerization due to the length of the aliphatic chain increasing. Surprisingly, the best results of adhesion to steel and shear strength were obtained for SAT based on epoxy acrylate resin with styrene (11 N/25 mm and 20.8 MPa, respectively). However, the thermomechanical properties of SAT with styrene were weaker than those with methacrylates. Full article
