Highly conductive plastic nanofibers self-assemble
CNRS via R&D Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers from CNRS and the Université de Strasbourg in France have succeeded in making highly conductive plastic fibers that are only several nanometers thick. These nanowires, for which CNRS has filed a patent, self-assemble when triggered by a flash of light. Inexpensive and easy to handle, unlike carbon nanotubes, they combine the advantages of the two materials currently used to conduct electric current: metals and plastic organic polymers. More



 SPE HIGHLIGHTS


A novel lightweight, flexible, conducting polymer composite
SPE Plastics Research Online    Share    Share on FacebookTwitterShare on LinkedinE-mail article
An immense number of different polymer composites exist, with many varied applications, and much research has been undertaken on them. Fillers or additives are introduced to the system to improve thermal and electrical conductivity and to stiffen the matrix. The resulting properties depend on the filler's type, shape, and volume fraction, and also on the crystallinity and crosslink density of the composite material. Trans-polyisoprene filled with the conducting polymer polyaniline greatly improves thermo-mechanical and thermal conductivity. More



Uniquely identifying polymer composite domains using energy-dispersive spectroscopy
SPE Plastics Research Online    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Sustainable materials are widely popular due to decreasing reliance on costly petroleum and the desire to focus efforts toward recycling and limiting energy use. Generating a highly-bio-based polymer composite requires immiscibly blending renewable-feedstock-derived poly trimethylene terephthalate and polyamide-6,10. Discriminating between microscopic regions of component polymers that have chemically similar structures enables characterization of the phase-inversion composition of a bio-based immiscible blend.

 PLASTICS INDUSTRY NEWS


Loss of key resin supply may hurt US vehicle production
The Detroit News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Automakers met at a hastily called summit to consider their options, after an explosion shut down a German factory that makes a key chemical used in plastics for brake and fuel systems. The industry is concerned that a shortage of the chemical could disrupt production in some U.S. auto plants. About 200 people, including more than 100 suppliers and representatives of auto companies, gathered to discuss alternative plastic resins, and ways to boost supplies from three other major producers.

Universal polymer technique to reduce work function of conductors
AZoM    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A team led by Bernard Kippelen of Georgia Tech has introduced a new method to decrease the work function of a broad range of conductors, including aluminum, gold and silver. They have applied an ultra-thin polymer layer of about 1-10 nanometers thick over the surface of the conductor to produce a strong surface dipole. More



Polymers perform non-DNA evolution
Royal Society of Chemistry    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Scientists have found that six polymer alternatives to DNA can pass on genetic information, and have evolved one type to specifically bind target molecules. They say that their work reveals both broader chemical possibilities for these key life functions and provides a powerful tool for nanotechnology and medicine. More

Plastics from plants vs. petroleum
Energy Digital    Share    Share on FacebookTwitterShare on LinkedinE-mail article
One of the leading bioplastics companies is Cereplast. Using starches from corn, wheat, tapioca and potatoes, Cereplast Compostables replace nearly 100 percent of the petroleum-based additives used in traditional plastics — pulling readily available crops from the Midwest, versus oil from the Middle East. Cereplast CEO Frederic Scheer is also responsible for establishing the Biodegradable Products Institute, a nonprofit organization that is now the largest biodegradable association in the world. In the following interview, Energy Digital gets a peek into the industry. More



Nissan sources Korean nanocomposite for center pillars
Plastics Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A polypropylene nanocomposite sourced from Korea has been adopted by Nissan Motor in the center pillars in one of its vehicles, saving up to 15 percent in weight. The Shinnano nanocomposite from Shinil Chemical Industry Co. exhibits superior processability when compared with talc-filled TPO by around 30 percent according to the supplier's estimates, and flow marks that would normally appear at a wall thickness of 1.8 mm for a talc-filled compound are nonexistent.

Low-cost solar cells from nanotube 'forests'
Rice University via Futurity    Share    Share on FacebookTwitterShare on LinkedinE-mail article
By replacing platinum with carbon nanotubes, researchers hope to make efficient solar cells at a fraction of the current cost for silicon-based solar cells. Single-wall nanotube arrays, grown in a process invented at Rice University, are both much more electroactive and potentially cheaper than platinum, a common catalyst in dye-sensitized solar cells, says Jun Lou, a materials scientist at Rice.

New polymer coating technique makes way for even thinner electronics
ZME Science    Share    Share on FacebookTwitterShare on LinkedinE-mail article
One of the cutting edge technologies currently used in manufacturing allows for printing materials directly onto a surface to create electrically functioning devices which are thin and flexible. The resulting devices become vulnerable to outside chemical phenomena, which makes the process expensive and the resulting device thicker. Scientists at Georgia Tech may have devised a work-around for this issue after they introduced a printed electronics atypical conductor with a low-work function by applying thin layer of polymer coating on the conductor's surface.

Recyclables may replace plastics in Fords
Detroit Free Press    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Retired U.S. currency and dandelions could find their way into Ford vehicle parts as rising costs of petroleum make it more expensive to manufacture plastics from scratch. Ford is researching the use of recycled or biological materials in place of plastics. For instance, more than 3.6 million pounds of retired paper money are shredded daily and could be used to make plastics for interior trays and bins. Russian dandelions offer a possible alternative to synthetic rubber. More

Survey: Most plastics firms expect to benefit from reshoring
Plastics News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
More than a third of large U.S.-based manufacturers plan to bring production back to the United States from China, according to a survey from the Boston Consulting Group. Plastics and rubber companies were the most favorable to reshoring — 67 percent of rubber and plastics companies surveyed said yes to the question: "Given the fact that China's wage costs are expected to grow 15-20 percent per year, do you expect your company will move manufacturing to the United States?"

Polymer concrete used for drain channels
The Hindu    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Polymer concrete is increasingly used for drain channels because of its zero water absorption, strength, as well as anti-corrosive properties. Made of resin, silicon, mineral aggregates and adhesives, it is not easily breakable, and can withstand very high pressure. Though four times stronger than conventional concrete, polymer concrete is only half its weight, making its usage that much more attractive. Given its inherent strength, it does not bend or get dislocated. More


Performance Fiber
Zeus performance fibers are commonly used in the aerospace, automotive, and textile industries. They can be used to create a braided sleeve or over-braid that is both expandable and flexible. The woven braiding can then be placed over existing wire assemblies to guard against chaffing and provide additional chemical wear resistance. The material is also used as a component in filters (semiconductor filters included) and conveyer belts. MORE
