ABSTRACT

 

The lamellar liquid crystal in water, tetraethyleneglycol dodecylether, and copper nitrate system has been investigated. The results which characterized using optical polarizing microscope and small-angle x-ray diffraction showed the stability of the liquid crystal region was 40% and 65% by weight of surfactant. The interlayer spacing of lamellar liquid crystal, with and without various concentrations of copper nitrate content, remained constant.

 

Keywords : Lamellar liquid crystal, Tetraethylene glycol dodecylether, Copper nitrate, Optical polarizing microscope, Small-angle x ray diffraction
