Adamantane-Modified Graphene Oxide for Cyanate Ester Resin Composites with Improved Properties

Blog Article

The conjugation of graphene and polymers has attracted great attention GLOSSY LIPSTICK PINK POOL #517 for the fabrication of functional hybrid nanomaterials.Here, we demonstrate the modification of graphene oxide (GO) with adamantane (AMT) through the diimide-activated amidation reaction.The modification of GO with AMT improves the dispersion and decreases the interfacial polarization of GO, causing a lower dielectric constant for the fabricated GO/AMT hybrid materials.

The structures of GO/AMT were studied by Fourier transform infrared spectroscopy and Raman spectroscopy.Furthermore, the mechanical properties, thermal stability, and dielectric constant of GO/AMT composites were measured at a low cured temperature using various Cocktail Table techniques, such as differential scanning calorimetry, thermogravimetric analysis, and dynamic mechanical thermal analysis.It was found that the synthesized GO/AMT materials with different contents were blended into cyanate ester (CE) resins, resulting in a lower cure temperature, smaller dielectric constant, higher thermal stability, and stronger water resistance.

It is expected that this novel GO/AMT-CE material will have potential applications for replacing traditional thermosetting resins.
