Folding graphene can make it even stronger

Graphene is strong - about 200 times greater than steel, but new research has shown that folding graphene nanoribbons can make a material that's ever stronger. The Chinese researchers call the new material Grafold.

The researchers say that while graphene is very high tensile strength (i.e. it is difficult to pull it apart) it is not strong under compression and cannot be squeezed. Grafold, however can withstand much larger amounts of compression (10-25 GPa depending on the structure of grafold compared with less than 2 GPa for graphene). The tensile strength is almost similar to graphene.

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at
