Questions

  1. Hello, I would like to know the ratio of acetone and water, and the size in dimation of the multilayer graphite. Thanks!

    1 answer
    1. Unfortunately, the ratio of acetone to water is proprietary. Note that the product Safety Data Sheet reports an acetone range of 70 - 90%. The size of multilayer graphite includes the thickness and the layer's lateral dimensions, which are 3-10 nm and 0.5-2.0 mm, respectively.
