“…For many decades, it has also been known that oxidized carbon black (oCB) is able to affect the cure behavior of epoxy resin systems [ 22 , 23 ]. In a recent paper, the WAXD patterns of oCB samples were interpreted by a disordered spatial arrangement of graphene oxide layers, exhibiting short in-plane correlation lengths [ 24 ].…”

This article compares the catalytic activities of oxidized carbon black (oCB) and graphene oxide (eGO) samples on the kinetics of a reaction of diglycidyl ether of bisphenol A (DGEBA) with a diamine, leading to crosslinked insoluble networks. The study is mainly conducted by rheometry and Differential Scanning Calorimetry (DSC). Following the same oxidation procedure, CB samples are more efficiently oxidized than graphite samples. For instance, CB and graphite samples with high specific surface areas (151 and 308 m 2 /g), as oxidized by the Hummers' method, exhibit O/C wt/wt ratios of 0.91 and 0.62, respectively. Due to the higher oxidation levels, these oCB samples exhibit a higher catalytic activity toward the curing of epoxy resins than fully exfoliated graphene oxide.

“…These interactions probably included hydrogen bonding between the –NH– sites of PANI and O–H/C–O groups of CB. 38 Furthermore, π–π stacking between the aromatic rings of CB and PANI possibly also existed. 39 These synergistic interactions could not only stabilize the structure of PANI and CB, but also ameliorate the PANI backbone conformation and promote the bipolaron-to-polaron transfer and polaron delocalization.…”

Microstructure and mechanical properties of epoxy resin/carbon black composites synthesized by in situ condensation polymerization of monomers in the presence of carbon black particles were investigated. SEM observation showed that carbon black particles were well dispersed in the epoxy resin matrix. The composite with 1 wt. % carbon black had the electrical resistivity of approximately 108.7 Ω•cm. The composites exhibited an a percolation threshold at carbon black content about 4 wt.%, indicating the existence of a path of percolation by connecting carbon black particles. Bending strength dramatically increased to a maximum value of 133.4MPa and then slowly decreased with content of carbon black increasing. Shore hardness increased gradually with content of carbon black and came to 23.3HD at carbon black 10 wt.%.
