The Influence of Concentration on the Morphology of Fibres Self-assembled by Ferrocenyl Surfacant and Methyl Orange.

Ionic self-assembly, the combination of the building blocks with opposite charge by electrostatic association, has many merits, such as simple, cheap and easy to get, flexible reversible and wide range of applications. In this paper, fibres were synthesized by combining surfactant N, N-dimethylferrocenylmethyl hexadecyl-ammonium bromide (Fc16AB) and fluorescent dye methyl orange (MO) using ionic self-assembly techniques. The morphology of self-assemblies with different concentration are measured and characterized by optical microscopy (OM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results show that the concentration of Fc16AB and MO has great effects on the morphology of obtained microfibers. [ABSTRACT FROM AUTHOR]
