Cleaner graphene powder has arrived
INAC researchers have developed an improved graphite exfoliation process that generates a graphene powder totally free of any type of metallic or organic contamination. Graphite exfoliation is the most commonly used method for making graphene powder in quantities ranging from grams to kilograms, and INAC’s new, patent-pending process eliminates a major bias that had been plaguing the study of graphene’s intrinsic properties.
For example, the magnetic behavior of this ultra-clean powder is 100 times more reliable than that of a conventionally-produced one—which illustrates the magnitude of the effect that contaminants can have. This new process is particularly attractive to scientists studying graphene for applications like catalysis, energy storage, and energy transformation.
