Tiivistelmä
Surfactants are chemical organic compounds tend to enrich strongly at interfaces which plays a vital role in both fundamental and applied sciences. They are amphiphilic in nature. Hydrophobic and hydrophilic parts are two main parameters in a surfactant molecule. Surface active compound gives a reduction in surface tension when it comes in contact with aqueous solution, which is the main fundamental property of surfactants. During the aggregation process the hydrophobic and hydrophilic part comes together as a monomer and forms a spherical shaped structure termed as micelles. Micelles have been a great interest in the field of bioscience. Critical micelle concentration of surfactant is an important term in surface chemistry, which is the concentration of solution above which all the surfactant monomers end to form micelles. This concentration provides a valuable guidance in comparing the detergency of surface active compounds. Micelles, surface tension, and critical micelle concentration are correlated terms with each other and can all be discussed together.
Surface tensions of different ionic liquids were measured in the Laboratory of Analytical Chemistry at the Department of Chemistry (University of Helsinki). Contact angle meter (CAM) was used for the measurement of surface tension. Fitting of curve method was applied to determine critical micelle concentration (CMC) value.
The value of CMC for all the ionic liquids was obtained as it was expected. Aggregation and surface property of newly synthesized ionic liquid was known by showing the strong surfactant property.
