You’re Not so Tough, h-BN

Hexagonal-boron nitride is tough, but Rice University scientists are making it easier to get along with.

Two-dimensional h-BN, an insulating material also known as “white graphene,” is four times stiffer than steel and an excellent conductor of heat, a benefit for composites that rely on it to enhance their properties.

Those qualities also make h-BN hard to modify. Its tight hexagonal lattice of alternating boron and nitrogen atoms is highly resistant to change, unlike graphene and other 2D materials that can be easily modified — aka functionalized — with other elements.

The Rice lab of chemist Angel Martí has published a protocol to enhance h-BN with carbon chains. These turn the 2D tough guy into a material that retains its strength but is more amenable to bonding with polymers or other materials in composites.
