“…The CAC value is significantly lower than the CMC after adding the ionic surfactant to the ionic polymer solution. When the solution consists of a non-ionic polymer and an ionic/non-ionic surfactant, the difference between CAC and CMC is not so significant [ 26 , 27 ]. Surfactant concentration also has a big impact on the core-shell fiber’s formation and properties.…”

Emulsion electrospinning is a method of modifying a fibers’ surface and functional properties by encapsulation of the bioactive molecules. In our studies, bovine serum albumin (BSA) played the role of the modifier, and to protect the protein during the electrospinning process, the W/O (water-in-oil) emulsions were prepared, consisting of polymer and micelles formed from BSA and anionic (sodium dodecyl sulfate–S) or nonionic (Tween 80–T) surfactant. It was found that the micelle size distribution was strongly dependent on the nature and the amount of the surfactant, indicating that a higher concentration of the surfactant results in a higher tendency to form smaller micelles (4–9 µm for S and 8–13 µm for T). The appearance of anionic surfactant micelles reduced the diameter of the fiber (100–700 nm) and the wettability of the nonwoven surface (up to 77°) compared to un-modified PCL polymer fibers (100–900 nm and 130°). The use of a non-ionic surfactant resulted in better loading efficiency of micelles with albumin (about 90%), lower wettability of the nonwoven fabric (about 25°) and the formation of larger fibers (100–1100 nm). X-ray photoelectron spectroscopy (XPS) was used to detect the presence of the protein, and UV-Vis spectrophotometry was used to determine the loading efficiency and the nature of the release. The results showed that the location of the micelles influenced the release profiles of the protein, and the materials modified with micelles with the nonionic surfactant showed no burst release. The release kinetics was characteristic of the zero-order release model compared to anionic surfactants. The selected surfactant concentrations did not adversely affect the biological properties of fibrous substrates, such as high viability and low cytotoxicity of RAW macrophages 264.7.

“…Practices of surfactant-polymer systems have been increased as industrial products by studying and better understanding their physical and chemical characteristics. Fields of use for such mixtures are quite extensive including detergents, painting and plating material, cosmetic and medicinal industries, mineral and oil refinery processes [3][4][5][6][7]. Although numerous studies [8][9][10] have been performed on interaction of pure surfactants with polymers, complex structure of such an interaction has yet to be thoroughly conceived [11,12].…”

Polymeric micelles supply an environment, which can be cautiously regulated for drug delivery. The self-assembly of polymeric micellization is dynamic. Micellization thermodynamic describes how the system defines the formation of micelles. The present study enables the micellization behavior of the surfactants in the presence of polymer to be examined by conductometric and tensiometric methods. The effects of polymer concentration and temperature on the micellization thermodynamics of a neutral soluble polymer and cationic cetyltrimethylammomium bromide (CTAB) surfactant mixture in aqueous medium were investigated. To examine polymer-surfactant interaction, critical micellar concentration (CMC) and thermodynamic parameters such as standard free energy ∆G, enthalpy ∆H and entropy ∆S are calculated by using a pseudophase model. Based on CMC, ΔG, ΔH and ΔH, the dependence of the compensation temperature on the polymer effect is discussed. This advanced work to understand micelle stability and compatibility can be comprehensively feasible in polymeric systems.

“…A surfactant is produced when a strong lipophilic, hydrophobic group is associated together with a strongly hydrophilic group in the same molecule [7]. Surfactants have been extensively used in the textile and fiber industry [8,9], paints [10], cosmetics [11], and polymers industries [12]. Besides this, it is also widely applied in pharmaceutical industries, mining purposes, recovery of the oil and paper industry [13].…”

Nanotechnology has gained huge importance in the field of environmental clean-up today. Due to their remarkable and unique properties, it has shown potential application for the remediation of several pesticides and textile dyes.Recently it has shown positive results for the remediation of sodium dodecyl sulfate (SDS). One of the highly exploited surfactants in detergent preparation is anionic surfactants. The SDS selected for the present study is an example of anionic linear alkyl sulfate. It is utilized extensively in industrial washing, which results in the high effluent level of this contaminant and ubiquitously toxic to the environment. The present review is based on the research depicting the adverse effects of SDS in general and possible strategies to minimizing its effects by bacterial degradation which are capable of exploiting the SDS as an only source of carbon. Moreover, it has also highlighted that how nanotechnology can play a role in the remediation of such recalcitrant pesticides.
