Title:
METHOD FOR MEASURING HYDROPHOBICITY (HYDROPHILICITY) OF SPECIMEN AND MEASUREMENT DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/159929
Kind Code:
A1
Abstract:
The present invention relates to a method for measuring the hydrophobicity (hydrophilicity) of a specimen and a measurement device therefor. The method for measuring the hydrophobicity (hydrophilicity) of a specimen according to the present invention comprises the steps of: disposing a bubble generating module for generating a bubble above a specimen; generating a bubble with the bubble generating module and moving the specimen and the bubble to each other to make a contact therebetween; and separating the specimen from the bubble, wherein, in the moving and separating steps, a contact surface between the bubble and the specimen is positioned in a phase different from a phase of the bubble, and force between the bubble and the surface of the specimen is measured.
