Synthesis, surface activity and antielectrostatic properties of new soft dichain cationic surfactants

“…Their ability to drain the surface charge reflected their strong hygroscopic properties related to the additional nitrogen atom in the studied soft surfactants. It has been already shown that hygroscopic liquids are more effective antielectrostatic agents since they can adsorb moisture from the atmosphere forming a monomolcular conductive layer on the surfaces and thus facilitate the charge outflow [25,30]. In the case of LDPE film all studied surfactants did not exhibit any antielectrostatic properties due to incomplete coverage of the polymer surface, caused probably by a crystalline form of both 2xC n A-Br, and 2xC n E-Br.…”

“…Many surfactants, particularly ammonium salts, have been found to be effective antelectrostatic agents [7,24,25,29,30]. They form a monomolecular conductive layer on the material surfaces by the attracted moisture or other solvents, and accelerate leaking of the electric charge.…”

New diamidequat-type surfactants in fabrication of long-sustained theranostic nanocapsules: Colloidal stability, drug delivery and bioimaging

“…Such products are designated for applications in the area of engineering nanostructures or functional interfaces as well as multipurpose tools in biological applications, e.g., in the template-assisted fabrication of drug nanocarriers [14][15][16]. Even slight modifications of the molecular structure with respect to the conventional single head-single tail design by, e.g., grafting with structural labile motifs as the acetal, amide, amine, ester, disulphide, ether or thioether moieties, may lead to new self-assembly and biological functionality of such products, their improved performance and, very often, lower toxicity [17][18][19][20][21][22]. The key issues in surfactant-based formulations are the structure-performance relationships and the chemical compatibility; therefore, much research is being devoted to these areas, especially in relation to the soft (otherwise chemodegradable, destructible, hydrolyzable, cleavable) structures [23][24][25].…”
