Abstract
The impact of the type and amounts of nanofiller on the features of the
glycidyl methacrylate-co-ethylene glycol dimethacrylate
(GMA-co-EGDMA)/organomodified montmorillonite (OMt) nanocomposites that were
prepared by in situ radical suspension polymerization, was examined.
Cloisite 30B and Cloisite 25A were used in this study as nanofillers, in
amounts of 2 and 10 wt.%. The structure, morphology, thermal stability and
porosity of the initial GMA-co-EGDMA copolymer and their nanocomposites were
examined by ATR-FTIR analysis, wide angle X-ray diffraction (XRD), scanning
electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS),
transmission electron microscopy (TEM), thermogravimetric analysis (TG) and
mercury porosimetry. It has been established that both clay nanofillers were
successfully incorporated into the structure of the initial copolymer,
simultaneously on their surface and also on cross-sectional area. Prepared
samples with 2 wt.% have predominantly exfoliated, while samples with 10
wt.% have some tactoids-aggregates structure of the OMt layers.
Thermogravimetric analysis revealed that after ~ 30 % of degradation, all
nanocomposites become more thermal stable than the initial copolymer. The
obtained results indicate that porosity parameters can be easily modified
with the addition of clay nanofillers and thus prepared nanocomposites
adjusted to specific purposes.
