摘要：

A facile method for preparing graphene-polyaniline composite is proposed without the necessity of using graphene oxide. By adding CdS nanoparticles into the in situ polymerization system consisting of graphene and aniline monomers, a graphene-polyaniline composite with a well-bonded interface is yielded. It is found that the nano-CdS particles act as a 'bridge', connecting (i) PANI via the electrostatic force of attraction between the electron clouds of the sulfur and nitrogen atoms and (ii) graphene by p-p stacking. Taking advantage of the effective interfacial interactions, a large enhancement (similar to 400%) of the photoelectronic performance in the composite is observed. The work opens up a path for maintaining the original structure and properties of graphene during graphene-polymer composite manufacturing.
