“…[1] Recently, it has been demonstrated that composite nanostructures of PANI and metals show significant enhancement of sensing and catalytic capabilities [2,3] and the PANI/Au system is considered to be of particular promise. [4][5][6] A number of different methods have been used to prepare PANI/Au composite nanostructures. [7][8][9][10][11][12][13] Among these, a ''one-step synthesis'' is the most attractive: where a gold salt acts both as the oxidant for aniline polymerization and as a source of metal atoms.…”

Self‐assembled hollow nanosphere composites of polyaniline and Au nanoparticles (PANI‐p‐TSA/Au) were chemically synthesized from solutions containing p‐toluenesulfonic acid (p‐TSA) with the addition of gold chloride trihydrate as the oxidant. The composite materials were characterized by SEM, TEM, and a range of spectroscopic methods. Spectroscopic characterizations confirmed that the polymeric product is a form of doped PANI, while electron diffraction and X‐ray diffraction showed that elemental Au was present in the PANI‐p‐TSA/Au nanocomposites. The room temperature electrical conductivity of the PANI‐p‐TSA/Au nanocomposites was two orders of magnitude greater than a PANI‐p‐TSA obtained in the presence of ammonium persulfate as the oxidant under the same conditions.magnified image

Conductive micro-patterned copper tracks were fabricated by UV direct-writing of a nanoparticle silver seed layer followed by selective electroless copper deposition. Silver ions were first incorporated into a hydrolyzed polyimide surface layer by wet chemical treatment. A photoreactive polymer coating, methoxy poly(ethylene glycol) (MPEG) was coated on top of the substrate prior to UV irradiation. Electrons released through the interaction between the MPEG molecules and UV photons allowed the reduction of the silver ions across the MPEG/doped polyimide interface. The resultant silver seed layer has a cluster morphology which is suitable for the initiation of electroless plating. Initial results showed that the deposited copper tracks were in good agreement with the track width on the photomask and laser direct-writing can also fabricate smaller line width metal tracks with good accuracy. The facile fabrication presented here can be carried out in air, at atmospheric pressure, and on contoured surfaces.

Silver nanoparticles, as a nanomaterial of noble metals, have been widely explored for their applications in catalysis, 8) electronics, 9) surface-enhanced Raman scattering (SERS) 10) and many other fields. Silver nanoparticles could be prepared by many methods, including chemical reduction in aqueous or non-aqueous solutions, 11,12) electrochemical reduction, 13) template method, 14) ultrasonic-assisted reduction, 15) photoinduced or photocatalytic reduction, 16) biochemical reduction, 17) irradiation reduction 18) and microwave-assisted synthesis.…”

In this study, silver nanoparticles with controlled morphologies including spherical-like nanoparticles, and silver nanowires were synthesized in a sodium bis (2-ethylhexyl) sulfosuccinate (AOT) reverse ternary nano-emulsion system. The morphology and structure of the silver nanoparticles are characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and ultravioletvisible (UVvis) spectrum. The result shows that the molar ratio of water to surfactant (w) is crucial for the formation and structure of the nano-emulsion droplets. The controlling of the morphologies of the silver nanoparticles can be achieved through simply adjusting AOT concentration and the formation mechanism of the silver nanoparticles with tunable morphology has been proposed.
