In the present work we have been synthesized zinc sulfide (ZnS) nanocrystals by precipitation method and embedded in 

polymer-elastomeric matrix. The obtained nanocomposites optical properties, crystallinity and surface morphology have 

been studied via UV–visible absorption spectra, X-Ray diffractometr and Atomic Force Microscope (AFM), respectively.    

Polyethylene (PE) (1g) and nitrile-butadiene rubber (1g) (NBR-26 marks) have been used for preparing polymer-

elastomeric composite films. Nitrile-butadiene rubbers and polyethylene have been dissolved at 50 ml chloroform (CH

Cl) 

and 50 ml benzene (C

), respectively. This polymer mixture solution was synthesized from oxidative 

chlorophosphonation reaction by participation of 4ml phosphorus thrichloride (PCl

). The reaction was carried out at 60°C 

temperature for ~30 min with stirring. 

For formation of ZnS nanoparticles we have prepared 10

solutions. These solutions have been used 50 ml for each sorbtion steps. Then metal-sulphide sorbsed  thin films which 

processing of salt solutions have been washed by distillation water and rinsed by PH-070A vacuum furnace drying 

incubator. This process were reapeted ten times and different dimension composite particles were formed. The synthesized 

nanocomposite materials also have been analyzed with Furye Transmission Infrared spectroscopy method and accordance 

of chemical groups have been characterized.  

The ZnS nanoparticles crystal structure and grain size of obtained nanoparticles have been analyzed and  determined 

with the X-ray diffraction method by using D2 Phaser powder diffractometer under CuK

 irradiation  ( λ = 1.54060 A°) . 

Transmission spectra of the structures obtained were measured by means of two-ray spectra spectrophotometer Specord 250 

plus in the range of wavelength of 200 - 800 nm. Moreover, the surface morphology of nanocomposites and distribution of 

ZnS nanocrystals has been studied by Atomic Force Microscopy (AFM).  

The X-ray diffraction shows the nanoparticles of ZnS are hexagonal crystalline (a=b≠c, a= 3.76220, b=3.762200, 

c=16.20000 and α=β=90° γ=120) with average grain size 5-11nm which has been calculated Debye-Scherer equation. ZnS 

nanoparticles average grain size was estimated 5-15nm by Atomic force microscopy after two cycle of sorption, which is 

also confirmed by the UV-Vis absorbance. The band gap of ZnS nanoparticles is found to be 3,7eV after four cycle is 

greater than the bulk due to quantum confinement in ZnS (3.3 eV)  crystalline
