Dynamic light scattering of nano-gels of xanthan gum biopolymer in colloidal dispersion

Abstract

between nano-gels to repulsive interaction, as the mass fraction of nano-droplets increased. The reorientation time (sr) of water nanodroplets decreased with MFD for water-in-oil AOT microemulsion comprising high concentration (0.0000625) of XG. On the other hand, decreasing concentration of biopolymer led to increasing the rotational correlation time of water nanodroplets with MFD. In conclusion, a single relaxation curve was observed for AOT inverse microemulsions containing different XG concentrations. Furthermore, the interaction between nanogels was changed from attractive to repulsive versus concentration of XG in the AOT RMs.
