More than 20 million tons of plastic are placed in U.S. landfills each year. Results from a new University of Missouri study suggest that some of the largely petroleum-based plastic may soon be replaced by a nonpolluting, renewable plastic made from plants.

Plastic as a conductor

Plastic that conducts electricity and metal that weighs no more than a feather? It sounds like an upside-down world. Yet researchers have succeeded in making plastics conductive and cutting production costs at the same time.

Fast molecular rearrangements hold key to plastic’s toughness

Plastics are everywhere in our modern world, largely due to properties that render the materials tough and durable, but lightweight and easily workable. One of their most useful qualities, however - the ability to bend rather than break when put under stress - is also one of the most puzzling.

Phthalates and flame retardants urge regulatory action

Exposure to Bisphenol A (BPA), phthalates and flame retardants (PBDEs) are strongly associated with adverse health effects on humans and laboratory animals. A special section in the October 2008 issue of Environmental Research, "A Plastic World" provides critical new research on environmental contaminants and adverse reproductive and behavioral effects.

Nanonet circuits closer to making flexible electronics reality

Researchers have overcome a major obstacle in producing transistors from networks of carbon nanotubes, a technology that could make it possible to print circuits on plastic sheets for applications including flexible displays and an electronic skin to cover an entire aircraft to monitor crack formation.

Nano-tech process produces plastics that are 10 times more stretchable

With oil prices hovering around $100 per barrel, coal is reemerging as a key raw material in the manufacture of the basic chemical materials used to make plastics, fertilizers, and hundreds of other products, according to an article scheduled for the March 17 issue of Chemical & Engineering News, ACS’ weekly news magazine.

“Nanohybrid” plastic may expand use of biodegradable plastic

harminka — Mon, 03 Dec 2007 12:23:46 -0600

Scientists in New York are reporting development of a new biodegradable “nanohybrid” plastic that can be engineered to decompose much faster than existing plastics used in everything from soft drink bottles to medical implants. The study is scheduled for the Nov. issue of ACS’ Biomacromolecules, a bi-monthly journal.

New plastic is strong as steel, transparent

Pioneering tests on odors from plastic water pipe

“Fruity plastic” may seem like a connoisseur’s description of the bouquet of a bottle of Chardonnay or Merlot gone bad. However, that was among several uncomplimentary terms that a panel of water “sensory experts” used to describe the odor of drinking water from the plastic piping that is finding its way into an increasing number of homes these days.
