The preparation of zeolite rich polymeric materials presents a challenge due to the zeolite settling
during synthesis, poor miscibility, the phase separation and generally insufficient interactions
between polymers and zeolites. Combination of LTA, i.e. MFI, zeolite and poly(methacrylic acid) in the
form of soft hydrogel network provided the stabilization of the zeolite particles and enabled synthesis
of composite hydrogels with very high zeolite concentrations (26-52 mass%).
The investigated morphological, mechanical and primary structural properties, water swelling ability
and thermal stability revealed high dependence on zeolite concentration and type. Zeolite particles
were uniformly dispersed in PMAA matrix as confirmed by SEM and there was no agglomeration or
zeolite leaching despite very high concentrations. FTIR spectra disclosed the existence of functional
groups of PMAA network and both zeolite types that interacted mutually and led to increased
crosslinking density.... The established interactions changed the PMAA chain dynamics around the
particles, especially of the LTA type, as showed by XRD. Having much more surface groups capable to
generate interaction with PMAA, LTA zeolite stronger affected all of the investigated properties.
Composites’ mechanics was improved both in dry and swollen state compared to the PMAA hydrogel
(up to 21.8 times for the sample with the highest LTA concentration). Thermal stability of the
composites increased with increasing zeolite concentration.
The composition-property correlations were determined making this work the base for further
development of tailor-made zeolite-PMAA composite hydrogels aimed for specific application.
Composites were tested as low-cost, regenerative, environmentally friendly sorbents and showed
better removal of cationic dye compared to both components (PMAA and zeolite) alone.
