Iranian Knowledge-Based Firm Develops Smart Contact Angle Meter

“The company's series of contact angle measuring devices are used in the field of analyses required for measuring surface characteristics and can provide the data needed by researchers with high accuracy and reliability,” said Amir Bahreyni, the project manager of the knowledge-based company.

Noting that contact angle measuring devices are designed to accurately measure static and dynamic contact angles, surface and interfacial tensions, droplet fall, and hysteresis, he said, “This device is semi-automatic and used for measuring static and dynamic contact angles, and surface tension. The device also features the company’s proprietary software for measuring contact angle and surface tension, with two years of free software support and updates.”

“The device is used in the fields of materials, chemistry and biotechnology, and the company’s series of surface angle measuring devices has undergone technical improvements in features like automatic leveling, triple injection systems and modular optical and imaging systems,” Bahreyni said.

The contact angle measuring device is an important means in the field of nanotechnology, which is used as one of the methods of material surface analysis. Using the device, different surface characteristics of nanomaterials can be detected and measured.

One of the applications of the contact angle device in nanotechnology is to check the surface properties and nanocoatings. By changing the contact angle, various parameters such as minimum contact angle and surface free energy can be measured and used as important parameters in checking the properties and modifying the surface.

Surface tension is an important concept in nanotechnology and has broad applications in that field. It refers to the force that exists between two immiscible phases at their contact, such as the boundary between a liquid and a gas or between two liquids.

One of the key applications of surface tension in nanotechnology is in the identification of nanoparticles and other nanostructured materials. By measuring the surface tension between these materials and different environments, researchers can acquire important information about their surface properties and behavior. For example, surface tension changes can be used to monitor the adsorption of nanoparticles on surfaces or to study the behavior of nanoparticles in different solvents.

Another important surface tension application in nanotechnology is in the development and optimization of nanomaterial synthesis methods. For example, controlling the surface tension during the synthesis of nanoparticles can help control their size, shape, and distribution, which are critical factors for the performance of nanoparticles in their various uses.

Surface tension also plays a role in the stability of colloidal materials commonly used in many nanotechnology applications. By understanding and controlling the surface tension between the particles and the surrounding environment, researchers can optimize the stability of these colloids, which is essential for long-term use in various applications.
