Article Preview

Sodium lignosulfonate -chitosan (SLS-CS) polyelectrolyte complex was prepared by alkaline lignin and chitosan as raw materials. The structure and thermal stability of SLS-CS polyelectrolyte were characterized by FTIR, XRD, DSC. The results indicated that NH3+ was formed by the protonated amino groups of chitosan and then came into SLS-CS polyelectrolyte complex with -SO3Na of sodium lignosulfonate through electrostatic adsorption. Compared with the sodium lignosulfonate and chitosan, the thermal decomposition temperature of SLS-CS raised and thus improved the thermal stability; the amorphous peak tends to decrease; SLS-CS polymer arrangement appeared more ordering, and the molecular interaction were enhanced.
