Ferroelectric polymers made more versatile

ScienceDaily.com: Nanotechnology News - 5 февраля, 2019 - 17:05
The ferroelectric polymer PVDF (polyvinylidene fluoride) has interesting properties and could be used to store information or energy. One of the main drawbacks of PVDF is that if you add extra functional groups to improve certain properties, this also interferes with its ferroelectricity. To solve this, scientists have created block copolymers from PVDF that leave its ferroelectricity intact, but allow them to tune its characteristics.

Large-scale synthesis of metal nanoclusters with thermal shocks

Nanowerk.com - 4 февраля, 2019 - 21:35
Researchers report significant advances in developing a high-temperature, fast nanomanufacturing technique for the large-scale production of ultra small metal nanoclusters decorated in a graphene host matrix. The size and morphology of the metal nanoclusters can be controlled by varying the reaction temperature and the mass loading of metal salt in the graphene aerosol nanoreactors. This one-step continuous aerosol-based thermal shock technique offers considerable potential for the manufacturing of well-dispersed and uniform nanoclusters stabilized within a host matrix.
