“…In all samples, peaks at 3050 cm −1 correspond to CH stretching of oxirane rings. [ 40 ] After humidity aging, it was observed in the spectra a shift displacement and an intensity increase at 2920 cm −1 and 2850 cm −1 . According to Aslan et al [ 38 ] and Akpinar et al, [ 40 ] the bands at 2920 cm −1 refer to the symmetric stretching of CH bond and the peak at 2850 cm −1 corresponds to aliphatic CH groups that may have arisen due to degradation of such samples in environments with presence of water.…”

Mechanical and thermal properties of epoxy‐multiwall carbon nanotubes (MWCNTs) at different fractions (0.0, 0.25, 0.5, and 1.0 wt%) were investigated. The dispersion of the nanotubes in an epoxy adhesive commonly used in an automotive application was performed using a grease worker. This device has a perforated plate, able to produce mechanical shear. To investigate the behavior of adhesive‐carbon nanotubes mixtures and the bonding performance, four groups were prepared using two different perforated plates, P1 and P2. All MWCNT‐epoxy were submitted to extreme environmental conditions, resumed as reference (non‐aged), 500 h at 100°C, 500 h at 95% of relative humidity at 40°C, and 500 h under salt spray. A reduction in glass transition temperature was observed with the addition of the nanofiller and no increases on statistic heat‐resistant index temperature were noticed in MWCNT‐epoxy produced using both plates. Changes in the peaks at 3300, 1510, and 835 cm−1 after aging were seen in infrared spectra. The MWCNT addition to pure epoxy increased the apparent shear strength by 14% using P1. In P2, which has the mechanical shear greater by a factor of 2, no significant differences were observed, due to defects and agglomeration of MWCNTs observed by image analysis.

“…The epoxy resin formed as a result of the reaction of Bisphenol A and epichlorohydrin which exhibited characteristic peaks of oxirane at 3057 cm −1 , benzene at 1500 cm −1 and carbonyl at 1700 cm −1 (Figures 10 and 11). [39][40][41] The presence of amine peaks from hardener that provide crosslinking in epoxy adhesives was explained by the N H bonds and it can be observed at nearly 3381 cm −1 . The change of peak intensity around this wavenumber and the C N peak at 1192 cm −1 indicated the crosslinking and curing of epoxy adhesives.…”

Investigations on the production and development of nanoparticle-reinforced polymer materials have been attracted attention by researchers. Various nanoparticles have been used to improve the mechanical, chemical, thermal, and physical properties of polymer matrix composites. Boron compounds come to the fore to improve the mechanical and thermal properties of polymers. In this study, mechanical, thermal, and structural properties of structural adhesive have been examined by adding nano hexagonal boron nitride (h-BN) to epoxy matrix at different percentages (0.5, 1, 2, 3, 4, and 5%). For this purpose, nano h-BN particles were functionalized with 3-aminopropyltriethoxysilane (APTES) to disperse the h-BN nanoparticles homogeneously in epoxy matrix and to form a strong bond at the matrix interface. Two-component structural epoxy adhesive was modified by using functionalized h-BN nanoparticles. The structural and thermal properties of the modified adhesives were investigated by scanning electron microscopy and energy dispersion X-ray spectroscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry, and thermogravimetric analysis techniques. Tensile test and dynamic mechanical analysis were performed to determine the mechanical properties of the adhesives. When the results obtained from analysis were examined, it was seen that the nano h-BN particles functionalized with APTES were homogeneously dispersed in the epoxy matrix and formed a strong bond. In addition that, it was concluded from the experimental results that the thermal and mechanical properties of adhesives were improved by adding functionalized nano h-BN particles into epoxy at different ratios.

“…In recent years, many researchers have used the idea of making polymer-based nanocomposites to improve the mechanical properties of polymeric materials because of their unique properties. [1][2][3][4][5] Among these, carbon nanostructures such as carbon nanotubes and graphene nanoplatelets have been considered by many researchers. Ayatollahi et al [6][7][8] reported that by adding 0.1 wt% of multi-walled carbon nanotubes to an epoxy adhesive, a slight improvement in the strength and modulus of elasticity and a 15% improvement in the toughness occurs.…”

In this study, the effect of adding functionalized aminated graphene oxide up to 0.3 wt% was experimentally investigated on the mechanical properties and fatigue behavior of an epoxy adhesive with intermediate toughness. Accordingly, graphene oxide was prepared by a modified Hummers method and was modified with 3-aminopropyltrimethoxysilane silane agent. Bulk samples were then prepared from neat and reinforced adhesive with different weight amounts of aminated graphene oxide. Dumbbell-shaped samples with a notch were used to limit displacement at break. The results showed the presence of 0.1 wt% and 0.3 wt% aminated graphene oxide nanoplatelets, as optimum weight percentages respectively for the mechanical properties and the fatigue life, improves the modulus of elasticity by 35% and the tensile strength by 44% as well as the fatigue life by about 72–241% under different cyclic loading conditions.
