Smart Materials

, 2015
The speed with which new materials are developed and brought to market today has no precedents in human history. We have available a myriad new materials derived from such traditional ones as wood, ceramics and glass; and we have materials that perfect the performances of the materials of modernity, from steel to plastics.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

Advanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.
