GB/T 36086-2018 "Nanotechnology—Measurement of contact angle of nanopowders—Washburn dynamic pressure method" specifies a method for measuring the contact angle of nanopowder materials using the Washburn dynamic pressure method. This method is based on the principle of capillary rise, where the contact angle of the powder with respect to a liquid is calculated by measuring the height and time of liquid penetration in a compacted powder column. It is used to evaluate the surface energy or wettability of nanopowders.
