Abstract EN
This experimental study deals with the synthesis, processing, and characterization of highly filled nanocomposites based on polyvinyl butyral/magnetite (PVB/Fe3O4) and polymethylmethacrylate/magnetite (PMMA/Fe3O4).
The nanoparticles are synthesized in an aqueous coprecipitation reaction and show a single particle diameter of approximately 15 nm.
The particles are sterically functionalized and covered by PVB and PMMA in a spray drying process.
The synthesized compound particles are further processed by injection molding to test specimens with filler contents up to 14.5 vol.-%.
PVB and PMMA specimen are processed as a reference as well.
The distribution of the nanoparticles is characterized by microscopy.
Besides a minor number of agglomerates and aggregates the nanoparticles are distributed homogeneously in the PVB composites.
Furthermore, the injection molded specimens are characterized with regard to their thermal degradation, polymer structure, and their mechanical and magnetic properties.
The presence of nanoparticles capped with ricinoleic acid shows significant decrease in degradation temperature and in glass transition temperature of PVB.
The degradation temperature of PMMA is increased by adding nanoparticles capped with oleic acid.
Dynamic-mechanical properties as well as the magnetic permeability of PVB and PMMA are improved significantly by adding nanoparticles.
