Abstract
Herein, the aggregation manner of the mixture of polyvinyl alcohol (PVA) and tetradecyltrimethylammonium bromide (TTAB) was performed in polyols (glucose, maltose and galactose) media over 300.55–320.55 K temperatures range with 5 K interval through conductivity measurement method. The micelle formation of TTAB + PVA mixture was identified by the assessment of critical micelle concentration (
) from the plots of specific conductivity (
) versus TTAB concentration. The degree of micelle ionization (
), the extent of bound counter ions (
) as well as thermodynamic properties (
,
and
) of TTAB + PVA systems have been estimated. The
values reveal that the micelle formation of TTAB + PVA mixture experience an enhancement in the manifestation of polyols. The values of free energy of micellization (
) are negative for the TTAB + PVA system in aqueous polyols media, suggesting a spontaneous aggregation phenomenon. The
and
values of TTAB + PVA systems direct that the PVA molecule interacts with TTAB through the exothermic, ion-dipole, and hydrophobic interactions. The thermodynamic properties of transfer were also determined for the move of TTAB + PVA mixture from H
O to water + polyols mixed solvents. The values of compensation temperature (
) and intrinsic enthalpy gain (
) were evaluated and discussed for the studied system.
