Characterization of Carbon Nanotube-reinforced Polyethylene Nanocomposite Produced by Cryogenic Ball-milling Process

Terife G., Narh K.A., New Jersey Institute of Technology, US

The morphology of polymer nanocomposite, and the degree of dispersion of the MWCNTs were studied using SEM and light transmission microscopy. Both MWCNT ropes and aggregates were observed; also wetting of the nanotubes by the [...]

Fabrication of poly(alizarin red)-carbon nanofibers composite film and its application as nitric oxide microsensor

Zheng D.Y., Hu C.G., Hu S.S., Hu C.G., Hu S.S., Wuhan University, CN

In this work, a poly(alizarin red) (PAR)-carbon nanofiber (CNFs) composite film was fabricated via a well-controlled in situ electro-polymerization method. This composite film exhibited good sensing and catalytic ability to the electrochemical oxidation of nitric [...]

Experiments to Investigate Electromagnetic Shielding Performance of Polyaniline-Coated Thin Films

Kim B.R., Lee H.K., Korea Advanced Institute of Science and Technology (KAIST), KR

Many studies on electromagnetic wave shielding/ absorbing materials have been performed. In particular, studies of novel materials have been carried out as an alternative to conventional shielding materials such as metallic materials. Recently, the investigation [...]

Mechanical and Moisture Resistance Performance of Silver Nanoparticle Reinforced Fish Skin Gelatin Films

Harding H., Ludwick A., Samuel T., Young S., Aglan H., Tuskegee University, US

Films from the biodegradable polymer gelatin have been studied for biomedical applications not only because of the film forming properties of gelatin, but also because of the availability and economical advantages of gelatin. In this [...]

Preparation and characterization of Sulfonated High Impact Polystyrene (SHIPS) ion exchange nanofiber by electrospinning

Hwang T.S., Choi E.J., Kwak N.S., Chungnam National University, KR

The study of nanofibers has been a subject of intensive research because of their unique properties and widespread applications in many areas. Among the various methods used to prepare nanofibers, electrospinning has been very attractive [...]

Effect of Size on Properties of Nano-Structured Polymers –Transition from Macroscaling to Nanoscaling

Lem K.W., Haw J.R., Lee D.S., Brumlik C., Sund S., Curran S., Smith P., Brauer S., Schmidt D., Konkuk University, KR

The growth in investment on the effect of size in nanoscience and nanotechnology has been astounding. Among the $12.4B spent in 2006 worldwide Nanotechnology research funding (Lux Research, 2007), at least 50%, that is >$6B, [...]

Design and multiobjective optimization of a novel reactive extrusion process for the production of nanostructured PA12/ PDMS blends

Pla F., Rached R., Hoppe S., Fonteix C., Nancy University, FR

The important demand of innovative materials implies the development of new processes and concepts for their design and optimization. This work deals with the manufacture, by reactive extrusion, of Polyamide 12 (PA12)/ Polydimethylsiloxane (PDMS) nanostructured [...]

Directing cell migration by electrospun fibers

Liu Y., State University of New York at Stony Brook, US

We would like to submit the abstract “directing cell migration by electrospun fiber” for the presentation in Nanotech conference 2010. We investigate the influence of substrate on cell migration. We show that it is possible [...]

Environmental Friendly Synthesis of Polypyrrole within polymeric Nanotemplates-mechanism of polypyrrole synthesis

Li X., Chan A., Groves M., Malardier-Jugroot C., Royal Military College of Canada, CA

This paper describes an innovative way to synthesize polypyrrole using self-assembly nano-templates poly (isobutylene-alt-maleic anhydride) (IMA) or poly (styrene-alt-maleic anhydride) (SMA). Understanding the details of the novel synthesis in great details would provide us profound [...]

Preparation of nickel doped multi-functional micro-patternable polydimethylsiloxane nanocomposite polymer with characterization of its magnetic, electrical and mechanical properties for soft MEMS/Lab on a chip applications
