12th ESBP European Symposium on Biopolymers, Lisbon, Portekiz, 1 - 03 Ekim 2025, (Özet Bildiri)
Biopolymers, which are eco-friendly alternatives to synthetic polymers,
are polymers that come from biological sources and are employed in various energy
and environmental applications. In this context, the development of sustainable membrane technologies
for green hydrogen production via water electrolysis presents a significant
opportunity for the application of natural biopolymers. As well as offering functional groups for chemical modification and
interaction with inorganic fillers, these polymers have excellent
biodegradability, biocompatibility, and film-forming properties. This study focuses on the fabrication of chitosan-gelatin-based
composite membranes enhanced with titanium-based metal-organic frameworks
(MOFs), MIL-125 and its amino-functionalized counterpart NH₂-MIL-125. Chitosan and gelatin were chosen as the fundamental biopolymers.
MIL-125 and NH₂-MIL-125 were synthesized via a solvothermal route by
following the procedure given in the literature. MOFs were incorporated into the chitosan-gelatin matrix through a solvent
casting method [8]. The prepared membranes were characterized using FTIR, XRD, SEM, and
TGA to assess structural integrity, crystallinity, morphology, and thermal
stability. Proton conductivity was measured using electrochemical impedance
spectroscopy (EIS), while water uptake and swelling behavior will be evaluated
gravimetrically. The NH₂-MIL-125 incorporated
membranes showed an enhanced proton conductivity, mechanical robustness, and
thermal resistance due to enhanced hydrogen bonding interactions between the
amino-functional groups of the MOF and the biopolymer chains. So, the role of
MOFs as both structural reinforcers and functional nanofillers was emphasized
in the membrane design strategy. This work demonstrated the potential of
integrating natural biopolymers with advanced porous materials such as MOFs to
create high-performance, sustainable membranes for clean energy applications.
The findings will contribute to the growing field of green materials science,
highlighting a bio-based approach for next-generation electrolyzer membrane
development.
