High-pressure homogenizer and method for manufacturing graphene using the same

A high-pressure homogenizer comprising a channel module comprising a microchannel through which an object for homogenization passes,

• wherein the microchannel is provided with a first channel to an Nth channel, wherein N is greater than 2, sequentially arranged along a direction through which the object passes,
• the channel module comprises an inflow channel in which the object is supplied to the microchannel and an outflow channel to which the object passing through the microchannel is introduced,
• the first channel is provided with a plurality of first baffles arranged so as to be partitioned into a plurality of spaces along a width direction or a height direction and sequentially, the Nth channel comprises a plurality of Nth baffles arranged so as to be partitioned into a plurality of spaces along a width direction or a height direction,
• in two adjacent regions among N regions of the microchannel, baffles provided in respective regions are arranged in a staggered state for each region based on a flow cross section of the microchannel,
• wherein the microchannel has a rectangular cross section perpendicular to the moving direction of the object for homogenization,
• wherein the rectangular cross section of the microchannel is a rectangular shape having a width larger than a height, and
• wherein the microchannel has a ratio of width to height of 2:1 to 10:1.
