Anti-counterfeit polymers work like fingerprints

(Phys.org)—When it comes to tagging items to prove their authenticity, the goal is to stay ahead of counterfeit technology. The best tags are unique, complex, easy to read, and difficult to reproduce. ...

New self-stretching material developed

Although most materials slightly expand when heated, there is a new class of rubber-like material that not only self-stretches upon cooling; it reverts back to its original shape when heated, all without physical manipulation.

Fine-tuned supramolecular polymerization

In nature, supramolecular complexes—chain-like structures that are composed of many small units linked mainly by weak non-covalent bonds—are assembled and disassembled in a precisely controlled way. Now, in work published ...

Hierarchically porous polymers with fast absorption

A research team at KAIST has developed a method to form micropores of less than 2 nanometers within porous polymers where 10 nanometers long mesopores connect like a net. The advantage of the porous polymers ...

New material makes water and oil roll off

Car finish, to which no dirt particles adhere, house fronts, from which graffiti paints roll off, and shoes that remain clean on muddy paths – the material "fluoropore" might make all this possible. Both ...

Heat-conducting plastic developed

The spaghetti-like internal structure of most plastics makes it hard for them to cast away heat, but a University of Michigan research team has made a plastic blend that does so 10 times better than its conventional ...
