A nanocomposite of colloidal graphene oxide (CGO) and polyaniline (PANI) was fabricated via in situ oxidation polymerization in the presence of CGO prepared via a modified Hummers method without a dopant, in which the graphene oxide was individually exfoliated. Its electrorheological properties and other physical characteristics were studied.

The nanocomposites of polythiophene and carboxylated multiwalled carbon nanotubes (MWCNTs) were synthesized by in-situ chemical oxidative polymerization method using anhydrous ferric chloride (FeCl3) as an oxidant. The MWCNTs functionalized and ultrasonicated to obtain uniform dispersion within the polythiophene matrix. Field emission scanning electron microscopy was used to characterize the mo...

Silver-Polyaniline (Ag-PANI) nanocomposites were prepared by in-situ oxidative polymerization of aniline monomer in sodium bis(2-ethylhexyl) sulfosuccinate (AOT) solution as an emulsifier. The synthesis of Silver-Polyaniline nanocomposites was investigated as a function of several parameters such as aniline concentration, concentration of emulsifier (AOT), concentration of oxidation agent and c...

These interesting biomaterials have found awide range of application including contact lenses, vehicles for drug delivery and scaffold in tissueengineering and...

We demonstrate a universal approach to assemble gold nanoparticles (AuNPs) into ordered robust nanostructures. Colloidal AuNPs are partially coated by thiol-containing ligands and then destabilised into anisotropic superstructures. In situ polymerization of the surface attached ligands produces enveloped nanoparticle networks with retained nanoplasmonic properties and enhanced stability.

A microporous carbon coated core/shell Si@C nanocomposite prepared by in situ polymerization exhibits a stable capacity of over 1200 mAh g(-1) with 95.6% retention even after 40 cycles, which makes it a promising anode material for lithium ion batteries.

A hydrophilic versatile polymeric monolith with multiple retention mechanisms including hydrogen-bonding, π-π and electrostatic interactions, was developed by a simple one-step in situ polymerization. High mechanical stability and excellent separation capabilities of various nonpolar and polar analytes were successfully achieved and employed for multiple separations in mixed-mode chromatography.

A new type of nanocomposite hydrogels based on covalent cross-linked interactions with excellent mechanical properties and good stability has been prepared by using in situ free-radical polymerization; polystyrene nanoparticles with photo-activity are used as the cross-linking agent.
