Surfactant - Wikipedia
网页Surfactants are chemical compounds that decrease the surface tension or interfacial tension between two liquids, a liquid and a gas, or a liquid and a solid. The word "surfactant" is a blend of surface-active agent, [1] coined c. 1950. [2]
Surfactant | Definition, Properties, Examples, & Facts | Britannica
网页Surfactant, substance such as a detergent that, when added to a liquid, reduces its surface tension, thereby increasing its spreading and wetting properties. In the dyeing of textiles, surfactants help the dye penetrate the fabric evenly. …
Surfactant Definition and Examples - Science Notes and Projects
网页2022年1月1日 · A surfactant is a compound that reduces surface tension between two phases, such as two liquids, a liquid and gas, or even a liquid and solid. For example, adding detergent reduces surface tension in oily water, making it easier to remove soiling from fabrics or cookware.
Surfactant Definition and Examples - ThoughtCo
网页2019年3月31日 · Surfactants or tensides are chemical species that act as wetting agents to lower the surface tension of a liquid and allow for increased spreadability. This can be at a liquid-liquid interface or a liquid- gas interface. Surfactant Structure.
Surfactant - an overview | ScienceDirect Topics
网页Surfactants are substances that create self-assembled molecular clusters called micelles in a solution (water or oil phase) and adsorb to the interface between a solution and a different phase (gases/solids).
Surfactant Definition & Meaning - Merriam-Webster
网页surfactant. noun. sur· fac· tant (ˌ)sər-ˈfak-tənt, ˈsər-ˌ. : a surface-active substance. specifically : a surface-active lipoprotein mixture which coats the alveoli and which …
Pulmonary surfactant - Wikipedia
网页Pulmonary surfactant is a surface-active complex of phospholipids and proteins formed by type II alveolar cells. [1] The proteins and lipids that make up the surfactant have both hydrophilic and hydrophobic regions.
Surfactants: Mechanism of action, Types, Applications - Science Info
网页2024年2月15日 · Surfaces refer to the interface between two substances that are not in the same phase. Surface active compounds reduce a substance’s surface tension by limiting intermolecular interactions. Surfactants used in industrial applications significantly reduce surface tension at low concentrations.
Structure and Applications of Surfactants - IntechOpen
网页2023年10月26日 · Surfactant molecules have two parts, a lipophilic (apolar) part that retains fat and a hydrophilic (polar) part that is miscible with water. The lipophilic portion consists of one or more aliphatic, straight or branched or aromatic or even alkylaromatic hydro- or fluorocarbon chains.
What Are Surfactants | School of Chemistry - University of Bristol
网页Surfactants, a contraction of the term surface-active agents, are amphiphilic (dual-natured) molecules because they possess both hydrophilic and hydrophobic groups. The general structure of a surfactant molecule is shown in the figure right.
