“…The number of cycles was determined to obtain a homogeneous dispersion while minimizing the loss of material and preventing particle damages from applied energy and residual stresses. [ 13,30 ] The homogeneity of particle dispersion resulted in a good interaction between the reinforced GNPs and matrix. Therefore, mechanical and thermo‐mechanical properties of the nanocomposites increased even at lower GNP contents compared to those of the ultrasonication samples.…”

Development and characterization of graphite nanoplatelets filled copolymer of benzoxazine and epoxy

In this study, graphite nanoplatelets (GNPs) were dispersed in a copolymer matrix consisting of bisphenol‐A based benzoxazine (BZ) and bi‐functional cycloaliphatic epoxy (CER), using two solvent‐free techniques: ultrasonication and three‐roll mill (3RM). The effects of GNP addition on the tensile performance, storage modulus, glass‐transition temperature (Tg), and electrical conductivity were evaluated. A maximum increase of nearly 46% and 20% in tensile modulus and strength, respectively, was found at 1.8 wt% of GNP content dispersed using the ultrasonication technique. In comparison, a superior enhancement with 55% and 37% increase in the tensile modulus and strength could be obtained at a lower GNP content, 0.9 wt%, dispersed via 3RM calendering, respectively. In the electrical conductivity measurement, a percolation threshold was achieved in the range between 0.6 wt% and 0.9 wt% of GNP content using the 3RM technique, which was in agreement with the predicted values. The theoretical stiffness obtained from the simplified Halpin‐Tsai model corresponded with the experimental data at low fractions. The incorporation of GNPs into the BZ/CER copolymer resulted in the full recovery of all the performance losses from the addition of CER to BZ. Choosing a proper dispersing technique, the 3RM calendering in this case, could lead to a minimum required GNP content for achieving superior nanocomposite performances.

“…f). The agglomeration is caused by stress transfer between epoxy resin and F‐GO accounts for the decrease in tensile and flexural strength . The tensile strength of the epoxy/F‐GO (0.5 wt%) composite increases to 113.88 and 31.62% when compared with neat epoxy and epoxy/GO (0.5 wt%) composites.…”

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.

Abstract:With the integration and miniaturization of electronic devices, thermal management has become a crucial issue that strongly affects their performance, reliability, and lifetime. One of the current interests in polymer-based composites is thermal conductive composites that dissipate the thermal energy produced by electronic, optoelectronic, and photonic devices and systems. Ultrahigh thermal conductivity makes graphene the most promising filler for thermal conductive composites. This article reviews the mechanisms of thermal conduction, the recent advances, and the influencing factors on graphene-polymer composites (GPC). In the end, we also discuss the applications of GPC in thermal engineering. This article summarizes the research on graphene-polymer thermal conductive composites in recent years and provides guidance on the preparation of composites with high thermal conductivity.
