The influence of barium ferrite nanoparticles on morphological and mechanical properties of ethyl cellulose based nanocomposites

Abstract

This study presents preparation and characterization of ethyl cellulose based nanocomposites. Successful use of simple solvent casting technique provided nanocomposites with high loads of barium ferrite magnetic nanopowder in the polymer matrix, promising significant improvement of mechanical properties. Investigation of morphology revealed formation of agglomerates that are still on nanoscopic level. Nanocomposite thin films with a higher content of the magnetic powder showed substantial enhancement of break strength, elongation and microhardness compared to the pure ethyl cellulose, which was the primary aim of this research.

Basalt-polyester hybrid composite materials for demanding wear applications

“…In order to provide better cavitation resistance, the material was improved by the addition of alumina particles that enable obtaining better mechanical properties when added to the polymer [8]. The proposed material can be treated as a hybrid one [9,10] as the added particles are of submicron dimensions and enable obtaining better matrix material that is surrounding the basalt particles [11][12][13]. As the matrix material, a commercial polyester resin was used.…”
