A new NIST test studies the safety of nanotubes inmodern plastics over time

Researchers at the National Institute of Standards and Technology (NIST) are analyzing the safety concerns of old plastics when they begin to decompose and disintegrate from exposure to weather conditions. NIST experiments can help scientists design better tests
to ensure that aging plastics do not become environmental or health hazards over time.
These kinds of tests are now more important than ever, because plastics are not what they used to be. Modern epoxies are often made stronger, lighter and more resistant with the addition of multi-walled carbon nanotubes (MWCNT). MWCNTs already improve plastics used in baseball bats, tennis rackets,
bikes and airplanes, and while these tiny tubes appear to be long-lasting, there is still no complete set of tests to determine what happens to them in the long term. Hence, a team at NIST has taken steps to change this.
