<P>Thermoplastic elastomer composites and nanocomposites were fabricated via melt processing technique by blending thermoplastic elastomer (TPEE) with poly(butylene terephthalate) (PBT) thermoplastic and also by adding small amount of organo modified nanoclay and/or polytetrafluoroethylene (PTFE). We study the effect of polymer blending on the mechanical and thermal properties of TPEE blends with and without nanoparticle additions. Significant improvement was observed by blending only TPEE and virgin PBT polymers. With a small amount (0.5 wt.%) of nanoclay or PTFE particles added to the TPEE composite, there was further improvement in both the mechanical and thermal properties. To study mechanical properties, flexural strength (FS), flexural modulus (FM), tensile strength (TS), and tensile elongation (TE) were all investigated. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) were used to analyze the thermal properties, including the heat distortion temperature (HDT), of the composites. Scanning electron microscopy (SEM) was used to observe the polymer fracture surface morphology. The dispersion of the clay and PTFE nanoparticles was confirmed by transmission electron microscopy (TEM) analysis. This material is proposed for use as a baffle plate in the automotive industry, where both high HDT and high modulus are essential.</P>

<P>Polymer–clay nanocomposites based on poly(3,4-ethylenedioxythiophene)/polystyrene sulfonate (PEDOT) : PSS and nanoclay montmorillonite were synthesized and characterized. The doping of PEDOT with polystyrene sulfonate made it water dispersible (PEDOT–PSS). Sodium dodecyl benzene sulfonate (SDBS) and ionic liquid were used to increase the interlayer spacing and the conductivity of the nanocomposites, respectively. The nanocomposite was characterized by various techniques, such as X-ray diffraction (XRD), TEM, surface resistivity, and thermogravimetric measurement analysis. Interlayer spacing increased as a result of the addition of SDBS, and this was confirmed by the 2&thetas; shift observed via XRD analysis. The surface morphology of the conductive coated clay was examined by TEM analysis. Good electrical surface conductivity, interlayer spacing, and polymer coating were observed for the material prepared using the surfactant and conductive ionic liquid. © 2009 Wiley Periodicals, Inc.

In this research, polypyrrole/silica nanotube/silver nanocomposites (PPy/SiNTs/Ag) were prepared via UV-induced dispersion polymerization of pyrrole monomer using silica nanotubes (SiNTs) as a template and silver nitrate as the photoinitiator. SiNTs were prepared from the natural halloysite nanotubes by the acid-leaching method. The SiNTs were then modified by silane coupling agent (3-APTES) in order to provide anchor sites for depositing of PPy/Ag nanocomposite chains. The formation mechanism, morphological, structure characteristics of the obtained PPy/SiNTs/Ag nanocomposites were reported. The PPy/SiNTs/Ag nanocomposites showed higher electrical conductivity and thermal stability than those of PPy/SiNTs nanocomposites. PPy/SiNTs/Ag nanocomposites exhibited excellent chemical catalytic property in the reduction of methylene blue in the presence of sodium borohydride within few minutes.

A facile approach for fabricating polypyrrole/carbon black nanocomposites (PPy/CB) decorated with silver nanoparticles with enhancing the electrocatalysis and the antibacterial property has been carried out via one-pot photopolymerization of pyrrole monomer using silver nitrate as photoinsentizer in the presence of carbon black (CB). Carbon black was functionalized by silane groups to provide anchor sites for the polypyrrole/ silver composite coating. The formation mechanism, structural, morphological properties, and electrical conductivity of the obtained PPy/CB/Ag nanocomposites were studied in detail. The electrical conductivity and thermal stability of the PPy/CB/Ag nanocomposites were higher than those of PPy/CB nanocomposites and pure PPy. The PPy/CB/Ag nanocomposites exhibited a well-defined response to the electrochemical reduction of hydrogen peroxide. Moreover, PPy/CB/Ag nanocomposites also showed excellent antibacterial activity against Escherichia coli bacteria.

Herein, we have demonstrated a facile and ultrafast technique to obtain carbon nanotubes (CNTs) growth on graphene oxide (GO) surface within just 10 s under ambient conditions via microwave assisted approach. The physicochemical characteristics of the hybrid materials were examined by field emission scanning electron microscope (FESEM), transmission spectroscopy (TEM), X-ray diffraction (XRD), Raman spectroscopy, and the mechanism formation was proposed. The obtained data indicated that GO/CNTs hybrid material decorated with silver nanoparticles exhibit good performance for hydrogen peroxide detection with the wide linear detection range of 0.1 to 100 mM, and detection limit of 1.5 μM (S/N ratio 3).

Improving the life time of water treatment membranes can be achieved through exquisite control of the active disinfectant release. The Ppresent study demonstrates a comparison between PES-Gr-AgNPs, PES-CNT-AgNPs and aminenated PES-AgNPs composite polymer membrane for silver release to check the life time of water treatment membrane. Antibacterial activities of the samples were carried out to investigate the disinfection performance of the samples on the Gram negative bacteria (Escherichia coli). A predominant relation between Silver release and disinfection was accessed using the as-synthesized membranes. The physical-chemical properties of the samples were examined by XRD, SEM-EDAX, and HRTEM analyses.
