“…These resins are being used in coatings, adhesives, hardware components, semiconductor encapsulation, and electronic circuit board materials due to their high performance properties such as tensile strength, high stiffness, exceptional electrical strength, and excellent chemical resistance, etc. [1][2][3] But, epoxy resins are brittle in nature with poor strength and toughness. 4,5 In order to overcome this problem, we need to incorporate modifiers (like polymer based nano-fillers) into the epoxy resin to ensure a remarkable enhancement in the mechanical and thermal properties of epoxy resins.…”

ABSTRACT:The present work has the objective of fabricating graphene oxide (GO) and amine-functionalized graphene oxide (F-GO) reinforced epoxy composites using the casting method. Epoxy resin was dispersed separately with GO (0.5 wt%) and F-GO (0.5 and 1 wt%), and then the epoxy resin mixture cured with triethylenetetraamine at room temperature. The synthesized GO and F-GO were characterized by FT-IR and Raman spectroscopy. The interfacial interaction of Si in the composite was studied by XPS. The formation of GO and F-GO was confirmed by XRD. The tensile and flexural strength composites were measured using the UTM. The thermal behavior and dynamic mechanical behavior were examined by TGA and DMA. The surface morphology and dielectrical properties were analyzed by SEM, TEM, and impedance analyses. The results obtained from epoxy/F-GO (0.5 wt%) composite revealed higher mechanical and thermal properties than neat epoxy and epoxy/GO composites.

Kraft lignin (KL) is extensively produced in industry but is mainly burned as fuel. To broaden its use, KL was grafted with dodecyl glycidyl ether to alter its thermal properties. The reaction of KL with dodecyl glycidyl ether (DGE) was analyzed using nuclear magnetic resonance (NMR), Fourier infrared spectroscopy (FT‐IR) and elemental analysis. Alternatively, KL was methylated to mask its phenolic hydroxy groups to investigate how phenolic hydroxy groups impact the grafting of the alkyl chain of DGE onto lignin (methylated Kraft lignin, MKL). The methylation facilitated the molecular weight enhancement and thermal stability reduction of Kraft lignin via grafting with DGE. The influence of grafting alkyl chains on the structural and thermal properties of KL and MKL was studied using thermogravimetric analysis and differential scanning calorimetry analysis. Our data suggest that, due to their high molecular weights and lower glass transition temperatures, the produced lignin derivatives may be promising feedstocks for composite production.

“…This is mainly due to the realization of the exceptional property enhancement achieved by these materials at low filler contents. Many studies have demonstrated that introduction of well‐dispersed nanofillers into polymer matrixes is very effective in improving their properties, including mechanical and thermal properties, as well as dielectric properties .

The preparation of crosslinked polyimide (PI) composites via a blending technique is reported. Different kinds of organic or inorganic silicon-based nanofillers have been used for this purpose. A comparison is made between carefully chosen pairs of fillers, the choice depending on the compatibility of the crosslinked PI with the filler, to study the effects of the crosslinked PI matrix structure and fillers with different micromorphology. The dispersion of the filler is characterized with SEM as uniformly dispersed or gelled. It is found that with different micromorphology of filler, the PI matrix can be loaded with different mass fractions of filler, and the point at which gelation occurs is not the same. In order to study this behavior, these fillers are subjected to a quadratic mean equation calculation and analysis. Compared to pure PI, all obtained crosslinked composites have a higher glass-transition temperature and a lower dielectric constant.
