Abstract:The structure of lyotropic liquid crystallineorgel like phases formedin starch/surfactant (cationicoranionic)/ water ternary phase systems in the temperature range of o Chas been investigated by XRD, SEM and FT-IR techniques. The ionic surfactants were cetyltrimethyl ammonium bromide (CTAB), sodiumd odecyl sulfate (SDS). The phases were in equilibrium with aqueous solutions at 60°C and contained 15-25wt% starch and 10-30wt % surfactant, depending on the charge density of the starch and the chain length of the… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
