Influence of the preparing of a biopolymer-surfactant system on its aggregation behavior.

Influence of the preparing of a biopolymer-surfactant system on its aggregation behavior.

Abstract

Multicomponent samples with identical composition, prepared with different order of single component addition, should show different behavior of its macroscopic or microscopic properties. This paper is focused on problematic related to the effect of the order of substances addition in a colloidal sample and the effect of initial form (liquid, solid) of each substance. As investigated system, biopolymer hyaluronan and cetyltrimethylammonium bromide (CTAB) was selected. This system has been studied in the aqueous, saline, and phosphate buffer environments. Fluorescence probe method and surface tension measurement were selected as indicators.
