Effect of surface treatment for carbon nanotubes on morphological and rheological properties of...

Poly(ethylene oxide) nanocomposites filled with functionalized multi-walled carbon nanotubes are prepared and characterized using rheological and morphological measurements. This study investigates how the surface treatment of carbon nanotubes (CNTs) affects the CNT dispersion state. It is found that the nanocomposites have a higher effective volume fraction than the real volume fraction of the CNTs. The dispersion state of the CNTs is identified by using field emission scanning electron spectroscope and transmission electron micro-scope. The rheological findings indicate that there exist

  • Chasing nanocomposites: nano-size particles have mega-potential in plastics because just a pinch does so much more than heavy loadings of other additives. Three recent conferences presented almost 200...
    • They are still in their infancy, but if the forecasts are right, nanocomposites could turn out to be the biggest little thing to hit plastics in decades. Polymers reinforced with as little as 2% to 5% of these particles via melt compounding or in-situ polymerization exhibit dramatic improvements in thermo-mechanical ......
  • Nanocomposites: a little goes a long way.
    • From auto parts to barrier packaging, the race is on to commercialize nano-clay thermoplastic composites. Just a pinch of these infinitesimally small particles can dramatically raise mechanical, thermal, barrier, and flame-retardant properties. Why all the excitement about the new class of mineral-reinforced plastics known as nanocomposites? Because relatively small amounts ......

    • Bits of clay improve TPO properties Thermoplastic olefin (TPO) nanocomposites, which use nanometer-sized clay particles as a reinforcement, have so far been discussed more than molded. But General Motors, Blackhawk Automotive Plastics, and Basell Polyolefins recently used this emerging materials technology in a commercial application—the step-assist (running board) for the ......
  • Conference Reveals Wider Range of Nanocomposites.
    • Nanocomposite technology is evolving in many new directions, as indicated by the program of the "Nanocomposites 2001" conference scheduled for June 25-27 in Chicago. The conference is sponsored by Executive Conference Management and cosponsored by PLASTICS TECHNOLOGY magazine. The two-day meeting will host 38 presentations by speakers from the U.S., ......
  • US polymer nanocomposites demand to exceed 7 billion pounds in 2020.
    • By 2010, nanocomposites demand will grow to nearly 350 million pounds, and will rise to over seven billion pounds with a value nearing $15 billion by 2020. Although the hype surrounding polymer nanocomposites has been in full-throttle for nearly a decade, the market for these new materials has not played ......
  • Prospecting paydirt.
    • Researchers are using nanoparticles of clay to raise polymers to new capabilities. IN THE LATE 1980s, Toyota Central Research Labs in Japan teamed up with Ube Industries Ltd., a Japanese resin supplier, to produce a new composite polymer, consisting of nylon 6 interspersed with layers of montmorillonite, a layered silicate ......
  • Nanocomposites: Broaden Roles in Automotive, Barrier Packaging.
    • Nanocomposites are gradually gaining acceptance in the mainstream of global plastics processing. These polymer compounds, containing relatively low loadings (under 6% by weight) of nanometer-sized mineral particles, are beginning to show up in polypropylene and TPO-based automotive exterior claddings (see sidebar), barrier beer bottles, nylon packaging films, polyethylene pipe and ......
