The siloxane-based multi-functional surfactant shows a very low critical micelle concentration
plus the lowest surface tension reading of all surfactants tested (Table 3).
Among the topics covered in the book are: "Techniques for studying block copolymers," "Dynamic processes in block copolymer melts," "The critical micelle concentration
," "Adsorption from block copolymer solutions," "Gelation in block copolymer solutions," "Structure formation in semicrystalline diblocks," "Crystallization kinetics in semicrystalline block copolymers," and "Theories for binary block copolymer/homopolymer blends." The text should prove valuable to the polymer and materials science researcher in both industry and academia, and to post-graduates in related fields, the publisher says.
Micellization occurs when the surfactant concentration is equal or less than its critical micelle concentration
(CMC) at which micelles form.
And the critical micelle concentration
, encapsulation efficiency, particle size, and micelle stability of the two amphiphilic copolymers were characterized.
Cellulose beads of the smallest mean diameter (26.5 [+ or -] 2.1 [micro]m) were obtained at 3% (w/v) Span 80 which corresponded to the critical micelle concentration
of Span 80 at 0.2 mM .
Thus, we have selected SEAR concentrations of 1.0 mM and 10.0 mM, which correspond to concentrations below and above the SEAR critical micelle concentration
(CMC) , respectively, to evaluate their impact on the reduction of [Ag.sup.+] and posterior stabilization.
In water, surfactants have a measurable property called the critical micelle concentration
. (4) This is the concentration at which micelles are formed and where surface tension reduction is greatest.
