The invention belongs to the technical field of
graphene, and particularly relates to a method for continuously preparing
graphene nanoplatelets by means of
grinding stripping.The method comprises the steps that crystallized
organic matter is uniformly dispersed in a
graphite precursor through
solvent dispersion, deformation force produced through repeated
crystallization of the crystallized
organic matter is utilized for enabling the
graphite layer frame distance to be increased, and intercalated
graphite is formed; the intercalated graphite is sent to a
grinding stripping
machine, the stripping and
grinding effect of
shear force formed in the mutual friction process of media and the graphite material is utilized, the intercalated graphite is stripped, and
graphene nanoplatelets are formed; screening separation is conducted on stripped graphite through a vibrating screening
machine, unstripped graphite is screened out to be stripped again, and the uniformly distributed graphene nanoplatelets are obtained.The number of
layers of the prepared graphene nanoplatelets ranges from 10 to 100, the
crystal structure is complete, the high-quality graphene nanoplatelets are produced in an efficient, low-cost and
continuous mode under a high shear condition, the preparation process is green and
environmentally friendly, and a significant market value is achieved.
