“…On the other hand, it can also be concluded from Figure 7a and the fitted parameters that increasing the molar ratio of the Diels-Alder adduct from 0.5:0.5 to 1:1 (compare EP-PU 1 with EP-PU 2) results in the increase of parameters b 1 , b 2 and b 3 . This indicates an increase in the E-modulus and a steeper dependence of σ on ε.…”

Abstract:The present work aimed at the preparation and investigation of different epoxypolyurethane (EP-PU) co-networks. The EP-PU co-networks were obtained by applying two different synthetic strategies, in which the coupling element, the Diels-Alder (DA) adduct, was prepared previously or formed "in situ" in the reaction between furan functionalized polyurethane and furfuryl amine-diglycidyl ether bisphenol-A oligomers (FA_DGEBA). For the synthesis of these EP-PU networks, poly(ε-caprolactone)-diol (PCD, M n = 2 kg/mol) and poly(ε-caprolactone) (PCL) with different molecular weights (M n = 10, 25 and 50 kg/mol) and 1,6-hexamethylenediisocyanate (HDI) were used. The EP-PU co-networks were characterized by Attenuated Total Reflectance Fourier-Transform Infrared spectroscopy (AT-FT-IR), differential scanning calorimetry (DSC) and dynamical mechanical analysis (DMA). Scanning electron microscopy (SEM) was applied to assess the morphology of the EP-PU samples. It was demonstrated that the stress-strain curves for the EP-PUs could be interpreted based on the Standard Linear Solid (SLS) model. The DMA traces of some EP-PUs (depending on the composition and the synthetic method) revealed a plateau-like region above the melting temperature (T m ) of PCL confirming the presence of cross-linked structure. This feature predicted shape memory (SM) behavior for these EP-PU samples. Indeed, very good shape fixity and moderate shape recovery were obtained. The shape recovery processes of these EP-PU samples were described using double exponential decay functions.

“…Commercial epoxy adhesives are engineered for optimal toughness by incorporating phase-separated thermoplastics, rubber particles, or rigid inorganic particles into the matrix. Typically, the adhesives are cured at elevated temperatures to increase their strength and activate chemical bonding at the substrate/adhesive interface [131][132][133][134][135].…”

This review article is a comprehensive study of different approaches utilized by various researchers for UV-cure epoxy composites through the cationic route in the form of transparent or colored composites either in thin films or thick dimensions. Generally UV curing is applied on thin and transparent materials, yet attempts are being made to cure intensely colored and thick composite samples. In recent times, thick sample UV-curing has been actively explored to decrease the processing and fabrication expenses of complex assemblies. In this article, data has been reviewed about epoxy curing with methodological trends, not only in thin films but also in thick samples.
