Abstract: 

Attempt to significant decreasing of permeability of polymeric material in versus liquid and gases for production of inert polymeric products in engineering applications have special situation in research. The purpose of this research is to study the permeability behavior of Acrylonitril-Butadiene copolymerre inforced by calcium carbonate nanoparticles in the temperature range 25-45oC and using the solvent permeability tests to microstructure evaluation of the polymer Nano composites. Results show the concentration of nano particle plays an important role in the diffusion, sorption and permeation coefficients and by increasing the amount ofnano-CaCO3 up to optimum content (10-15%) decrease in the secoefficients (22% decrease in diffusion coefficient)is observed, whereas for higher concentrations, especially at higher temperature increasing trend were obtained for the secoefficients. By increase temperature, diffusion mechanism is more close to Ficki an mechanism. Increase of nano particle concentration in Nano composite decrease ultimate swelling and diffusion rate of solvent and also activation energy (up to two fold).The micro structure and the dispersion of nano-CaCO3 in the polymer matrix was evaluated using SEM micrographs and an appropriate relationship was established between the micro structure and the experimental results(permeability and mechanical properties).In general, swelling test and mechanical analysis an delectron micro scope images were presented similar behavior for prepared nanocomposites and can be recommended that swelling and permeability test scan be used as an inexpensive and simple method to characterization and evaluation of the properties of polymer nanocomposites.
