Fabrication of Encapsulated Gemini Surfactants

Abstract

(1) Background: Encapsulation of surfactants is an innovative approach that allows not only protection of the active substance, but also its controlled and gradual release. This is primarily used to protect metallic surfaces against corrosion or to create biologically active surfaces. Gemini surfactants are known for their excellent anticorrosion, antimicrobial and surface properties; (2) Methods: In this study, we present an efficient methods of preparation of encapsulated gemini surfactants in form of alginate and gelatin capsules; (3) Results: The analysis of infrared spectra and images of the scanning electron microscope confirm the effectiveness of encapsulation; (4) Conclusions: Gemini surfactants in encapsulated form are promising candidates for corrosion inhibitors and antimicrobials with the possibility of protecting the active substance against environmental factors and the possibility of controlled outflow.

Wetting effect of branched anionic Gemini surfactant aqueous solution on PMMA surface

“…12 Furthermore, Gemini surfactants exhibit superior chemical stability and antioxidant properties, which render them effective in safeguarding metal surfaces against chemical corrosion and aging. 13 When compared to conventional surfactants, Gemini surfactants exhibit higher surface activity and lower CMC. However, there has been limited research on the adsorption behaviour of cationic Gemini surfactants on polymer surfaces, 7 although the adsorption behaviour of amphoteric surfactants 14 and cationic Gemini surfactants 15 on PMMA surfaces has been already reported.…”
