Product Introduction

Contact angle: The angle formed by placing a droplet of liquid on a solid surface, forming a solid liquid gas three-phase system interface. The angle formed by the two tangent lines of the gas-liquid interface and the solid-liquid interface sandwiching the liquid phase is called the contact angle, also known as the wetting angle or wetting angle, represented by the symbol 0. The unit degree (°) of contact angle 0 ranges from 0 to 180 °. When 0-0 ° or non-existent, it is spread (completely wetted). When 0<90 °, it is wetted (hydrophilic)

When 0-90 °: the boundary standard for wetting or not. When 0>90 °: non wetting (hydrophobic)

When 0-180 °: completely non wetting (ideal state that does not exist)

The instrument consists of an image acquisition system, backlight source, droplet module, sample stage, control unit, measurement software, etc. The measurement step is to extrude a droplet onto a solid surface or suspend it at the front end of a needle tube, then capture the contour of the droplet projected by a backlight source and optically enlarged using a camera, transmit it to a computer to obtain a clear image, and finally measure and calculate precise data including contact angle, forward contact angle, backward contact angle, rolling angle, droplet volume, liquid tension, solid surface energy, and spreading coefficient through software. Note: Some data requires hardware support to be measured
