Clay-polypropylene (PP) nanocomposites (NCs) were prepared by melt processing. Two types of PP with different levels of crystallinity were used. Mixtures of the two PPs were made at different ratios that generate a varying degree of crystallinity for the final NC samples. The level of micro- and nanodispersion of the organoclays and the microstructure of the resulting NCs were characterized by means of various techniques, including X-ray diffraction analysis, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and differential scanning calorimetry (DSC). The result

  • 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 ......
  • 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: 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 ......
  • Clay-filled 'nanocomposites' offer extraordinary properties.
    • They are generating a lot of excitement despite the secrecy surrounding their development. They are said to exhibit dramatic improvements in mechanical, thermal, barrier, and flame-retardant properties, all without significant loss of toughness or clarity. These new reinforced plastics, known as nanocomposites, contain very tiny platelets of a special type ......
  • The difference a clay makes.
    • An article on nanocomposites in the May issue of Plastics Technology (p. 76), included a mislabeled photo. The published photo showed the results of compounding different nanoclays in semi-rigid PVC. The label and caption incorrectly described the photo as heat-aging of polypropylene nanoclay composites. The two correctly labeled photos are ......
  • Additives for polyolefins: newest, advances add ruggedness, good looks & easier processing: at a recent conference, suppliers revealed novel coupling agents for wood composites and nanocomposites, unusual...
    • Although a wide range of new additives were discussed at the SPE Polyolefins 2005 conference held in Houston earlier this year, one theme stood out strongly. This was the emergence of novel coupling agents to satisfy the growing interest in improved processing and performance for polyolefin natural-fiber composites and mineral-filled ......
  • 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 ......
