دراسة تأثير إضافة مسحوق كاربوكسي مثيل سليلوز إلى بولي اثلين واطئ الكثافة على الحجب الإشعاعي للأشعة السينية

Abstract EN

The research involved synthesis and characterization of three liquid crystal compounds of Schiff’s base (mesogenicleg and and its complexes with ions of ( K2PtCl6) , (MnCl2 .4H2o) as the following structure.

the leg and and their complexes have been characterized by ultra violet (UV), a spectrophotometer Infrared (IR), , polarizing microscope equipped with heating stage, It was found that these compounds have nematic liquid crystalline status (enantiotropic).The crystal structure was studied for prepared compounds using X-ray diffractometer (XRD), and it has shown that ligands have a mixture of cubic and hexagonal structures, the complex (CE (1) ) is a mixture of cubic and tetragonal structures , while the second complex (CE (2)) It was found to be a combination of orthorhombic, rhombohedral and monoclinic structure.
