摘要
Abstract
The effect of four water-soluble polymers including sodium alginate,xanthan gum,carbopol 940,and sodium polyacrylate in the liquid crystal emulsions have been described in this work,through the experiments including stability tests,thermal gravimetric analysis,and rheology.The results show that the addition of carbopol 940 has no effect on the liquid crystal structure and particle size,but performs the best in centrifugation stability.In addition,xanthan gum helps the emulsion to preserve at room temperature,with the largest proportion of bound water and liquid crystal content.The rheological tests show that the four liquid crystal emulsions are non-Newtonian liquids.Incorporation of carbopol 940 increases the viscosity,thixotropy loop area and viscoelasticity of the emulsion,as well as increases the ability of the liquid crystal structure to withstand external forces and not easy to deformate.In conclusion,this paper provides experimental basis for the application of water-soluble polymers in the formulation of liquid crystal emulsions.关键词
