Catalytic effects of copper oxides on the curing and degradation reactions of cyanate ester resin

Abstract: The catalytic effect of copper oxides on the curing and degradation behaviors of the cyanate ester resin is studied with infrared spectroscopy, attenuated total reflection infrared spectroscopy (ATR), differential scanning calorimetry (DSC), and thermogravimetry analysis (TGA). The result of infrared spectroscopy and DSC analyses indicates that accelerated curing effects from different additives are in the order of zinc octoate > cuprous oxide > cupric oxide. The exothermic characteristics of the cyanate ester… Show more

“…Generally, the thermal decomposition of copper oxide starts from 300 °C. The remaining small changes evidently arose from variations in MK10 composition 64 66 . We found analogous observations in sand_PEI_Cu NPs for PEI, copper oxide and sand composition.…”

“…Due to the incorporation of carbon nanotubes, the gel times of MW-CNTs=CE CE systems with different mass fraction of nanotubes is obviously decreasing compared with the pure CE resins. It indicates that the reaction activity of CE systems with MW-CNTs is increased with the incorporation of carbon nanotubes, which is similar to the catalytic effects of copper oxides [34] . The main reason is that the hydroxyl on the surface of carbon nanotubes can accelerate selfpolymerization to form thiotriazinone of CE resin, which can be proved by the enhanced thiotriazinone characteristic peak at 1565 cm À1 and 1370 cm À1 on the FTIR spectra in Figure 5.…”
