“…Mixed GNP/MWCNT efficiently suppresses the SW process and therefore increases the coating resistance and the coating capacitance, as described in SW section. Comparable results have been observed for EPYR/GNP/MWCNT 20,30 , which also refer to the presence of sufficient amount of nanollers for preventing the SW process; this is also in accordance with the results of the gravimetric experiments.

“…Nyquist plots for pure EPYR, EPYR/GNP/MWCNT 2 and EPYR/GNP/MWCNT 5 showed similar behavior; on comparison, we found that EPYR/ GNP/MWCNT 20,30 exhibited quite good coating results. CRv values of EPYR/GNP/MWCNT 10 were the highest among the values of the measured compositions, closely followed by those of EPYR/GNP/MWCNT 20,30 . Both EPYR/GNP/MWCNT 2,5 displayed lower CRv values than that obtained for pure EYPR.…”

“…However, a slight decrease and/or remaining constant aer 168 hours of immersion is observed for EPYR/GNP/MWCNT 10 . It is clearly observed that the CRv values of EPYR/GNP/MWCNT 10 are the highest values among the values for the measured compositions, closely followed by those of EPYR/GNP/MWCNT 20 and EPYR/GNP/ MWCNT 30 . Both EPYR/GNP/MWCNT 2,5 display lower CRv values than that obtained for pure EPYR.…”

“…7 C. Neat EPYR showed the highest value compared to the other products. CDT max values also displayed gradual decrease with the increasing nano-ller content except for the value of EPYR/GNP/MWCNT 30 . CDT nal values were also in the range from 455.8 C to 444 C. The thermal results clearly indicated that the mixed GNP/MWCNT nano-llers have no signicant effects on T 10 , CDT max and CDT nal temperatures for pure EPYR; on the contrary, signi-cant effects on the in situ electrical conductivity measurements were observed.…”

“…Before attempting this step, a small weight loss is detected up to 110 C, which mainly refers to the loss of entrapped solvents and moisture on the surface of these composite materials. 24,25 In the range of 400-410 C and during decomposition, pure EPYR and EPYR/GNP/MWCNT 20,30 show higher thermal stabilities than other materials. EPYR/GNP/MWCNT 20 shows remarkable increase in the thermal stability compared to previously mentioned materials.…”

The present study is aimed to fabricate composite materials containing epoxy resin (EPYR) reinforced by mixed carbon-based nano-fillers in the form of graphene nano-platelet (GNP) and multi-walled carbon nanotube (MWCNT) using the dissolution casting technique with the help of ultrasonic assistance. The pure epoxy resin was reinforced by variable loading of mixed GNP/MWCNT in situ, and the epoxy resin is denoted as EPYR/GNP/MWCNT 2-30 . The numbers 2-30 corresponded to the final mass ratio of the nano-fillers. The designed products were reinforced by variable percentages of GNP/MWCNTs. XRD, FT-IR, thermal analyses, FE-SEM, TEM and electrical conductivity were utilized as identification techniques to confirm the structures of these composite materials. An excellent evidence for the composite formation was given by XRD diffraction patterns and FT-IR spectroscopy. The introduced amounts of mixed nano-fillers showed significant effects on the thermal, conducting and coating behaviors of pure EPYR. Pure EPYR and EPYR/GNP/MWCNT 20,30 showed higher thermal stabilities than other materials in the range of 400-410 C. EPYR/GNP/MWCNT 20 also showed remarkable increase in the thermal stability compared to other materials. T 10 represents the temperatures at which 10% weight losses are examined.Pure EPYR and its related EPYR/GNP/MWCNT 2-30 displayed similar thermal stabilities at T 10 temperature (330 AE 4 C). The morphological features were examined by SEM and TEM; these features showed that the nanocomposite components were extremely compatible. The in situ electrical conductivity values showed noticeable enhancement for the formulations of EPYR/GNP/MWCNT 2-10 . Moreover, the coating performance of EPYR was tested by water uptake experiments and electrochemical impedance; both tests proved that the mixed GNP/MWCNT nano-fillers remarkably improved the pure EPYR coating due to the ionic charge transfer resistance and elevated barrier behaviour. The coating resistance variations values (CRv) of EPYR/GNP/MWCNT 10 were the highest among the measured composition values, closely followed by those of EPYR/GNP/MWCNT 20 and EPYR/GNP/MWCNT 30 .

Polymer nanocomposites are usually made by incorporating dried nanoparticles into polymer matrices. This way not only leads to easy aggregation of nanoparticles but also readily brings about opaqueness for nanocomposites based on functionally transparent polymers. In this letter, transparent ZnO/epoxy nanocomposites with high‐UV shielding efficiency were prepared via two simple steps: first, in situ preparation of zinc hydroxide (Zn(OH)2)/epoxy from the reaction of aqueous zinc acetate (Zn(Ac)2·2H2O) and sodium hydroxide (NaOH) at 30°C in the presence of high‐viscosity epoxy resin; second, thermal treatment of the as‐prepared Zn(OH)2/epoxy hybrid into ZnO/epoxy composites. Optical properties of the resultant ZnO/epoxy nanocomposites were studied using an ultraviolet–visible (UV–vis) spectrophotometer. The nanocomposites containing a very low content of ZnO nanoparticles (0.06 wt %) possessed the optimal optical properties, namely high‐visible light transparency and high‐UV light shielding efficiency. Consequently, the as‐prepared ZnO/epoxy nanocomposites are promising for use as novel packaging materials in lighting emitting diodes technology. © 2012 Wiley Periodicals, Inc.

In this article, copper (Cu) crystallites were successfully prepared via low temperature molten salt method, and the possible formation mechanisms were proposed. The conductive fillers of multiwalled carbon nanotubes (MWCNTs) and as‐prepared Cu particles were designed and introduced into acrylonitrile‐butadiene‐styrene (ABS) blend to prepare different conductive composites. The dispersion states of conductive fillers and the morphologies of the composites were characterized using a field emission scanning electron microscope. The electrical resistivity of different composites was measured. The results showed that Cu and MWCNTs exhibited a synergistic effect in decreasing the electrical resistivity of the Cu/MWCNTs/ABS composites, because Cu that could locate between MWCNTs chain segments provides a better charge transport in the conductive pathways. Compared with pure ABS, the tensile strength, elastic modulus and thermal stability of the Cu/MWCNTs/ABS composites were significantly improved with the incorporation of Cu and MWCNTs. © 2014 Wiley Periodicals, Inc.
