Abstract

The invention relates to a simple measuring device for a surface contact angle. The device comprises a rack, a sample load bearing table, an optical system, an optical system three-dimensional translation table, a liquid-moving machine and a computer; the rack is of a right angle bent plate structure; the sample load bearing table comprises a turn table and a sample one-dimensional translation table, wherein one end of the turn table is fixed to the inner wall of a vertical plate of the rack, the other end of the turn table is fixedly connected with the sample one-dimensional translation table, a sample load bearing panel is arranged on the upper end face of the sample one-dimensional translation table, and samples to be detected are placed on the sample load bearing panel; the optical system three-dimensional translation table is arranged on a horizontal plate of the rack, the optical system comprises a zoom lens and a CCD camera, wherein the optical system is arranged on the optical system three-dimensional translation table, and the CCD camera is connected with the computer. According to the device, common light machine components on the market are used sufficiently, assembling and constructing can be conducted by oneself according to the need anytime anywhere, and through low cost and high disassembly and assembly flexibility, the requirements of measuring accuracy and measuring environment of a contact angle and frequent measuring times are met.

Description

technical field [0001] The invention relates to the technical field of surface contact angle measurement, in particular to a simple measuring device for surface contact angle, which can be used for measuring the unknown intrinsic contact angle of new materials, and can also be used for measuring the self-contact angle produced by micro-nano technology. The contact angles of clean micro-nanostructured surfaces were measured. Background technique [0002] The contact angle is an important parameter to characterize the wettability of a liquid on a solid surface. With the continuous emergence of new materials, the measurement of their surface contact angle has become one of the indispensable means to understand their wetting characteristics. At present, the special measuring instruments for measuring surface contact angle have been fully developed for different application requirements. The high-temperature and high-vacuum contact angle measuring instrument that has appeared i...
