whats the full name for fullerenes?
buckministerfullerenes
what are fullerenes?
an allotrope of carbon that has a hollow closed cage shape each carbon atom forms 3 covalent bonds with each other this means they were very hard
why do fullerenes conduct electricity ?
each carbon atom forms 3 covalent bonds with each other this leaves on electron free to conduct electricity
what are some uses of fullerenes?
they can be used to deliver drugs because they are hollow they can be used as lubricants because each fullerene can roll over eachother they can be used as catalysts
what are carbon nanotubes?
tiny tubes of pure carbon with each carbon atom forming 3 covalent bonds. these covalent bonds make the carbon nanotubes strong whilst being extremely light
what are some uses for carbon nanotubes?
the reinforcement of tennis rackets ot microchips they can also make technology faster and touch screens are being developed using nanotubes to make them strong light and conduct electricity
do carbon nanotubes conduct electricity?
as the carbon atoms from 3 covalent bonds there is on espare electron that becomes delocalized making it an excellent conductor of electricity
what is graphene?
a single layer of graphite
how can graphene be made?
by pulling layers of graphite off
why can graphene conduct electricity?
it forms 3 covalent bonds leaving one free electron that can carry charge making it a strong, flexible, light conductor
why is graphene better than carbon nanotubes?
because graphene is just better at everything than carbon nanotubes
