Synthesis of Silver Nanoparticle Using Some Cationic Surfactant and Their Applications

Abstract

Surface active agents are considered as important compounds which have important applications in various industrial fields. In addition to participate in the formulation of emulsions and phase transfer catalysis, surface active agents are used as biocides to inhibit or kill the growth of bacteria and fungi. As a result of the integrated usage of the surface-active agents in several industrial fields, their improvement was urgent to synthesize new types which characterized by higher efficiency in their applications and also to decrease the used dose. The unique improvement of the surface-active agents was introducing cationic groups in their skeleton as well as self-assembled on the silver nanoparticles to improve their adsorption at the different surfaces. That increased their efficiency as biocides considerably. The main results concluded from this thesis can be summarized in the following topics: 1. A series of cationic surfactants was synthesized based on m
