“…The broad peak obtained between 3400 and 3200 cm −1 for all EPZ nanocomposites is due to hydroxyl (─OH) group, which signified the interaction between ZnO and EP resin . Further, the peak at 1036 cm −1 indicates the formation of linkages between ZnO nanoparticles, APTES, and EP resin as shown in Figure . Thus, the appearance of the above peaks confirms the successful synthesis of EPC and EPZ nanocomposites.…”

“…Hence, to overcome the limitations of poor mechanical and adhesion properties, they are blended with stiff polymers such as epoxy (EP) resin . The various advantages of EP resin coatings are its outstanding adhesion, excellent toughness, dimensional stability, chemical and saltwater resistance, ease of curing, and excellent engineering properties . Multifunctional coating system can be designed by optimum selection of base polymer materials, which perform as barrier layer and reinforcing agents that prohibit the diffusion of corrosive media into the base matrix .…”

Multifunctional epoxy-polydimethylsiloxane nanocomposite coatings with antifouling and anticorrosion characteristics have been developed via in situ polymerization method at different loading (1, 3, and 6.5 wt.%) of ZnO nanoparticles to cater marine applications. A detailed comparative analysis has been carried out between epoxy-polydimethylsiloxane control (EPC) and ZnO-reinforced coatings to determine the influence of ZnO loading on various properties. The incorporation of ZnO in EPC led to increase in root mean square (RMS) roughness to 126.75 nm and improved hydrophobicity showing maximum contact angle of 123.5°with low surface energy of 19.75 mN/m of nanocomposite coating as compared with control coating. The differential scanning calorimetry (DSC) result indicated improved glass transition temperature of nanocomposite coatings with highest T g obtained at 83.69°C in case of 1 wt.% loading of ZnO. The increase in hydrophobicity of the system was accompanied by upgraded anticorrosion performance exhibiting 98.8% corrosion inhibition efficiency (CIE) as compared with control coating and lower corrosion rate of 0.12 × 10 −3 mm/year. The Taber abrasion resistance and pull-off adhesion strength results indicated an increment of 34.7% and 150.7%, respectively, in case of nanocomposite coating as compared with the control coating.The hardness of nanocomposite coatings was also improved, and maximum hardness was found to be 65.75 MPa for nanocomposite coating with 1 wt.% of ZnO.Our study showed that the nanocomposite coating was efficient in inhibiting accumulation of marine bacteria and preventing biofouling for more than 8 months. The developed environment-friendly and efficient nanocomposite material has a promising future as a high-performance anticorrosive and antifouling coating for marine applications. | MATERIALSEP resin, i.e., DGEBA, Araldite GY-251 with EP equivalent value ranging from 180 to 189 g/eq and EP value of 5.30 to 5.55 eq/Kg, and hardener triethylene tetra amine (TETA, Aradur HY-951) with amine value 24.04 g/eq were purchased from M/s.

Nanocomposites are worn resistant materials used in cutting tool applications. The materials are composed of ultrafine powder hard phase grains surrounded by a tough binder phase carbon nanotubes (Mo2C)1-x–(TiC)x (2≤x≤4)//1Wt% SWCNTs. Composite bicarbide Mo2C-TiC was rapidly synthesised and simultaneously consolidated by field activated sintering technique (spark plasma sintering) at which the extensive volume expansion occurred as a function of the volumic fraction from 20 to 40 vol.% of TiC powders and 1 Wt.% of SWCNTs was reinforcement of the NCMC’s. The sintered powder mixture was examined by XRD patterns, the morphology of the obtained phase was observed by SEM and the phase compositions in different regions were analyzed by EDX. The composites were processed using Field Activated Sintering Technique, spark plasma sintering (SPS) at temperatures in the range of 1700-1800°C with addicting of SWCNTs. The effects of SWCNTs addition on phases morphology, microstructure hardness and fracture toughness of the nanocomposite were investigated. The best product contained 1.0 Wt% SWCNTs from (Mo2C)1-x–(TiC)x , x= 0.2 which was sintered at 1700°C, 70 MPa for 10 min, M0.8T0.2/ 1 Wt% SWCNTs exhibit a better density, highest hardness and good ductility. Relative densification was achieved 99.5 % from the theoretical and good mechanical properties like hardness and fracture toughness (KIC=5.6 Mpa m1/2) are improved. The results were confirmed using Raman scattering resonant spectroscopy.

How does the cerium (Ce) doping in ferrimagnetic magnetite (Fe 3 O 4 ) affect the crosslinking state and kinetics of epoxy crosslinking with amine curing agents?To answer this question, we electrochemically synthesized nanoparticles of Ce-Fe 3 O 4 and characterized them by FTIR, XRD, FE-SEM, EDX, TEM, and XPS analyses. The presence of Ce atoms in Fe 3 O 4 crystalline lattice increased the surface area and active hydroxyl sites of the prepared magnetic nanoparticles (MNPs) associated with partial shrinkage of molecular lattice. The MNPs uniformly dispersed in epoxy resin and unconditionally tagged epoxy nanocomposites as Excellent cured systems. The effect of lanthanide doping on the cure kinetics of epoxy with amine was explored applying nonisothermal DSC and model-free kinetic approaches, signifying that Ce-Fe 3 O 4 nanoparticles facilitated epoxy ring opening by intensification of etherification reaction whatever the heating rate. Even at very low loading of Ce-Fe 3 O 4 nanoparticles into the epoxy (0.1 wt.%), the average apparent activation energy significantly decreased by ≈10%. This outcome would highlight the role of crosslinking on the ultimate properties, such as anticorrosive and/or self-healing characteristics contributed by Ce-doped nanoparticles once added to epoxy coating formulation.
