DEVICE FOR MEASURING THE SURFACE ENERGY OF SOLID BODIES
Application
The device for measuring of the surface energy of solid bodies is used to define the activation degree, modification, adhesion properties, wettability, surface energy, surface tension, roughness of thin layers and coatings on the surface of polymers, semiconductor materials by contact angle measurement of wetting.
Measuring technique
It is based on the contact angle measurement of wetting on demarcation line of 3 mediums gas-liquid-solid. A fixed size liquid (1-10 microliter) is applied to the surface explored. A drop is entrapped and detected on the surface automatically. At the real-time mode the main geometric characteristics such as limiting wetting angle, height, width of a drop are displayed. On the basis of the received data the vital parameters of surface layers (degree of activation, modification, adhesiveness, surface energy, and surface tension) are computed.
Application area
Can be applied for academic and research purposes, as well as in microelectronics, food, paint and varnish industry, pharmaceutics, beauty industry, optics and printing.
Characteristics
