A method for measuring the size and size probability distribution of free volume regions in polymeric materials using ultrafast infrared (IR) polarization-selective pump–probe experiments is presented ...

Inventing a polymer isn’t a feat accomplished overnight. Or, in some cases, even in a decade. For GE Plastics (Pittsfield, MA; www.geplastics.com), it’s been nearly 20 years since the company last ...

Plastics are long chains of specific polymers. The use of plastics has grown significantly owing to their high strength, high stiffness, high formability, and lightweight. Additionally, the most ...

Conductive organic materials often derive their electronic properties from highly organized crystal structures. Now, researchers have developed an organic polymer that conducts electricity like a ...

The preparation of dense Si 3 N 4-based ceramics has attracted great attention due to the achievable improvements in mechanical properties and high-temperature oxidation resistance. In general, the ...

The structure of semi-crystalline polymers largely depends on how strongly their molecular chains are entangled. Following numerous experiments, researchers developed a new model to predict the ...

Polymers are a popular material for everyday objects and have many industrial applications, with their use increasing rapidly. However, for new polymers to be developed and commercialized is often a ...

Starting with billions of molecules of monomer in a reactor, heat and pressure are applied in the presence of catalysts, causing one of the monomer double bonds to rearrange into two "half-bonds," one ...
