The hydrogen bonding between the carboxyl groups of carbon nanotubes (CNTs) and the polymer chains of metal oxide precursors can initiate the deposition in a self-assembly manner. Then metal oxide coated-carboxylated CNTs or coated-carboxylated graphene sheets hybrid materials are obtained by pyrolysis or hydrolysis.

Environmentally Friendly Approach

Cationic polyelectrolyte poly(diallyldimethylammonium chloride) (PDDA) was used to stabilize graphene sheets in the self-assembly of AgCl/PDDA/Graphene heterostructure. The resultant AgCl/PDDA/Graphene nanocomposites were characterized by Scanning electron microscopy, Atomic force microscopy and X-ray photoelectron spectroscopy. The results showed that AgCl nanoparticles with sizes of 500 nm uniformly positioned on the PDDA stabilized graphene sheets surface. This work presents a facile and environmentally friendly approach to the synthesis of AgCl/PDDA/Graphene and opens up a new possibility for preparing graphene-based nanomaterials for large-scale applications.

The Aesthetic

In the past two decades, we have learned a great deal about self-assembly of dendritic metal oxide structures, partially inspired by the nanostructures mimicking the aesthetic hierarchical structures of ferns and corals. The self-assembly process involves either anisotropic polycondensation or molecular recognition mechanisms. The major driving force for research in this field is due to the wide variety of applications in addition to the unique structures and properties of these dendritic nanostructures. Our purpose of this minireview is twofold: (1) to showcase what we have learned so far about how the self-assembly process occurs; and (2) to encourage people to use this type of material for drug delivery, renewable energy conversion and storage, biomaterials, and electronic noses.

AbstractFunctionalized graphene-based nanocomposites have opened new windows to address some challenges for increasing the sensitivity, accuracy and functionality of biosensors. Polyaniline (PANI) is one of the most potentially promising and technologically important conducting polymers, which brings together the electrical features of metals with intriguing properties of plastics including facile processing and controllable chemical and physical properties. PANI/graphene nanocomposites have attracted intense interest in various fields due to unique physicochemical properties including high conductivity, facile preparation and intriguing redox behavior. In this article, a functionalized graphene-grafted nanostructured PANI nanocomposite was applied for determining the ascorbic acid (AA) level. A significant current response was observed after treating the electrode surface with methacrylated graphene oxide (MeGO)/PANI nanocomposite. The amperometric responses showed a robust linear range of 8–5,000 µM and detection limit of 2 µM (N = 5). Excellent sensor selectivity was demonstrated in the presence of electroactive components interfering species, commonly found in real serum samples. This sensor is a promising candidate for rapid and selective determination of AA.
