摘要: The current research focuses on the preparation and characterization of polystyrene/bentonite composite materials with improved physicochemical properties biological activity. Bentonite particles were immobilized into polystyrene matrix by mechanical dispersion, films obtained. New data structure composites discovered using SEM, optical microscopy, XRD, IR UV spectrometry, tensile microbiological testing. effect filling agent morphology crystal was revealed. Insertion bentonite resulted in an increase interplanar layer distance clay. It found that adsorption kinetics methylene blue pure polymer controlled pseudo-first-order kinetic equation. Isotherms good agreement Langmuir model. For a 5 wt% filler content, maximum monolayer capacity ten times greater than unmodified polymer. concluded modification development new adsorption-active centers. strengthening testing results showed insertion (5 wt%) strength. In addition, antifungal against Candida albicans.
