A novel silicon-containing hyperbranched epoxy (SHBEp) has been explored via a one-pot A 2 + B 3 polycondensation reaction using (3-glycidyloxypropyl)trimethoxysilane (A-187) and excess neopentyl glycol (NPG) under solvent-free and catalyst-free conditions. We investigate for the first time bismaleimide (BMI) toughening effect using the fabricated polymer, and a series of SHBEp/BMI thermosets are then constructed, and then their mechanical properties like impact strength, flexural strength, and thermal stability are studied; meanwhile the toughening effect of SHBEp and conventional epoxy resin E51 is also compared. The results indicate that a proper addition of SHBEp (8 wt%) can significantly improve the toughness and thermal performance of thermosets compared to E51 with the same content. It is, therefore, revealed that the polymer is promising to act as an effective BMI toughener. Unexpectedly, a bright blue photoluminescence is observed when the SHBEp is excited under 365 nm UV light, and its average fluorescence lifetime and absolute fluorescence quantum yield are 4.30 ns and 4.61% respectively. It is demonstrated by our primary investigation that the epoxide and hydroxyl groups simultaneously help the light emission. Thus, the SHBEp bearing unconventional chromophores is also particularly expected to be a new light-emitting material. † Electronic supplementary information (ESI) available: GPC curve, the predicted 29 Si NMR of the obtained polymer, TGA and DSC curves, and additional hyperbranched polysiloxanes.

“…The rGO-MoS 2 obtained in the last step was used for the iron decoration process. The procedure was very simple and straightforward involving the mixing of Fe 3 O 4 nano-particles with rGO-MoS 2 (1:4 and 1:2) 34 . The mixture was again transferred to Teflon lining reactor and kept in oven at 180 °C for 18 hours.…”

Magnetorheological fluids (MRF) that undergo a change in their viscoelastic properties under the magnetic fields have been considered as one of most important smart functional materials for vibration dampers and shock absorbers in several engineering applications. However, the use of magnetorheological fluids in practical applications has been limited by poor sedimentation ratio and on-state yield stress. Herein, we report hybrid rGO-MoS2 additives for a high-performance magnetorheological fluid. Two different kinds of hybrid additives, which are called non-magnetic rGO-MoS2 and magnetic Fe-rGO-MoS2, were synthesized by using a hydrothermal method. The rGO-MoS2 added suspensions remained stable for the first 90 min whereas the CIP MRFs settled down quickly (65%) in the first 10 minutes. The Fe-rGO-MoS2 additives showed a 24% higher on-state shear stress as compared to CIP MRFs. On the other hand, an increase of 60% in the on-state yield stress for Fe-rGO-MoS2 MRF can be attributed to the gap-filling by the hybrid additives during columnar-structure formation. Among two-dimensional (2D) materials, Molybdenum Disulphide (MoS2) is a member of transition metal dichalcogenides (TMDCs), traditionally used as solid lubricant, while reduced graphene-oxide (rGO) is a well-known 2D material with supreme mechanical properties. We believe that this study will blaze the new way for developing a high-performance magnetorheological fluids based on various 2D material hybrids.

“…Mo has excellent wettability with metal and carbide and usually acts as the matrix strengthening phase, which could obviously improve the strength of the composite. Meanwhile, Mo is a solid lubricant when it oxidizes into MoO 3 at high temperatures [17][18][19][20][21][22][23]. Zheng et al fabricated the TiC-Mo composite coating by vacuum plasma spraying and investigated its microstructure and tribological property.…”

NiCrAlY and NiCrAlY-Mo coatings were fabricated by atmospheric plasma spraying (APS). The corrosion-wear performance of the coatings was investigated in artificial seawater and the synergistic mechanism between wear and corrosion were evaluated in detail. Results showed that the diffraction peaks of Ni3Al shifted to the right and the microhardness of the coating was improved from 329.8 HV to 342.5 HV with adding the Mo element. Meanwhile, the NiCrAlY-Mo coating had a lower friction coefficient, with a wear rate of 0.26 and 3.69 × 10−6 mm3/Nm, compared to the NiCrAlY coating with a wear rate of 0.37 and 4.67 × 10−6 mm3/Nm. The NiCrAlY coating had severe corrosion and the corrosion mainly occurred in grain boundary. Adding the Mo element, the Mo element was distributed in the grain boundary and the coating had a lower corrosion rate and visibly slighter corrosion. The NiCrAlY-Mo coating had excellent corrosion-wear properties in artificial seawater.
