Preparation and characterization of foamed polyurethane/silicone rubber/graphite nanocomposite as radio frequency wave absorbing material: The role of interfacial compatibilization

Optimizing the degree of carbon nanotube dispersion in a solvent for producing reinforced epoxy matrices

“…Both the amine and carbonyl groups are two moieties can coordinate with the graphitic surface of CNTs [53,64]. Due to these mechanisms, the effect of dispersion agent of BYK 9077 on the dispersion stability of CNTs in the solvent is much better than the oleic acid which is consistent with the highest degree of dispersion, as judged by the SEM and UV-vis analysis of BYK 9077 shown in Figure 8 and Figure 9(a).…”

“…ACCEPTED MANUSCRIPT 18 Unlike the oleic acid consisting of a hydrocarbon chain ending in a carboxyl group, the presence of amine groups in addition to the carbonyl groups in the molecule structure of BYK 9077 can induce a bifunctionaly characteristic [64], providing two perfect sites for dispersion of CNTs when they are ultrasonically treated in the copolymer-ethanol solution. Both the amine and carbonyl groups are two moieties can coordinate with the graphitic surface of CNTs [53,64].…”

Facile preparation of graphene nanoribbon filled silicone rubber nanocomposite with improved thermal and mechanical properties

“…Furthermore, the GNR was observed distributing randomly without obvious aggregations within the SR matrix. It has been known that GO could disperse within the SR uniformly because GO had interactions with the SR [36]. Thus the good dispersion of the GNR in the SR could be also ascribed to the good interactions between them.…”

“…Moreover, unlike the branched AP432 copolymer and linear copolymers such as Pluronics L64 triblock and F127 copolymers, 1 the bifunctional characteristic in BYK 9076 can enhance the coordination degree with the graphitic surface of CNTs. 21 Because BYK 9076 copolymers have a much lower cmc of 0.78 mg/mL and could form much bigger micelles compared with linear copolymers (192 mg/mL for L64 triblock 28 ), they can be a good candidate to achieve a high level of CNT dispersion. These effects result in one point; that is, BYK 9076 copolymers hold great potential in dispersing CNTs at a much lower concentration and can give smaller CNT bundles.…”

“…20 The presence of amine groups as well as carboxylic functionalities 21 makes BYK 9076 a strong dispersant.…”
