Thermodynamics Study of Monomer Adsorption Process for Fabrication of Conductive Textiles
Conductive textiles can be fabricated by a two-stage method involving adsorption of organic monomers by fibers and successive oxidation polymerization. Thermodynamics studies of monomer adsorption process with and without the existence of anionic surfactant or nonionic surfactant were investigated in this article. From thermodynamic analysis results,it can be concluded that the standard affinity (△μ0),enthalpy (△H0) and entropy change (△S0) of aniline monomers towards polyethylene terephthalate (PET) fibers are 7.48 kcal/mol and 0.029 kcal/mol K,respectively. It can be deduced that the anionic surfactant or nonionic surfactant plays a role of increasing the solubility of aniline monomers in aqueous solution for the decrease of standard affinity (-△μ0) and that the addition of anionic surfactant leads to the increase of standard enthalpy (△H0),with the monomers strongly integrated into the polymer chains of substrates. The results of the thermodynamic study indicated that the adsorption processes are endothermic and spontaneous because of the positive value of △H0 and negative value of △G0.
