Capillary-active describes a substance or a process that modifies or influences the behavior of liquids within narrow, hair-like tubes or capillaries. This activity often involves changes in surface tension, promoting or hindering liquid spreading, wetting, or penetration. These substances can either enhance capillary action, drawing liquids upward, or diminish it, causing liquids to resist entering or moving through the capillaries. The term is frequently encountered in fields like material science, biology, and cosmetics, highlighting the significant role these substances play at interfaces.
Capillary-active meaning with examples
- The detergent was designed to be highly capillary-active, efficiently reducing surface tension to allow water to penetrate deep into fabric fibers and lift away dirt and grime during the wash cycle. This property is key to its cleaning power.
- Specialized coatings applied to surgical tools are often designed to be minimally capillary-active, preventing blood from clinging to the surface and simplifying sterilization processes. This is very beneficial in infection prevention.
- In the creation of artificial blood vessels, researchers often prioritize the use of capillary-active materials to encourage the necessary flow of nutrients and waste products through the tiny channels within the structure. These processes are necessary for bio-compatibility.
- A key characteristic of the new ink formulation is its capillary-active nature, allowing it to flow smoothly and consistently through the narrow channels of the printer head, ensuring a sharp and uniform print quality. It's a critical aspect of the design.
- Certain plant roots exhibit capillary-active properties, enabling them to efficiently absorb water and dissolved minerals from the soil even against the force of gravity. This characteristic is how plants survive in many environments.
