Abstract
We synthesized alkyl-functionalized graphene oxide by the reaction of alkyl bromide and commercial GO to improve the interaction between the filler and the matrix in GO/PI nanocomposites. A-GO/PI nanocomposite materials were prepared by in situ polymerization of aromatic dianhydride (PDMA) and aromatic diamine (ODA) with added, welldefined, alkyl-functionalized GO. The A-GO/PI composites had an 18% increase in tensile strength and a 45% improvement in the modulus with a low content of A-GO (0.5 wt%). In addition, the A-GO/PI composites had better mechanical properties than n-GO/PI composites due to the strong interfacial interaction between A-GO and matrix polymer.
