12th ESBP European Symposium on Biopolymers, Lisbon, Portekiz, 1 - 03 Ekim 2025, (Özet Bildiri)
Membrane
separation technique has become more and more popular because of its low energy
consumption, ease of use, controllability, and scalability Biopolymeric
composite membranes are used as biosensors and electrochemical sensors in
sectors such as food and pharmaceuticals, as well as in wastewater treatment
and energy storage areas. Highly
selective membranes with high penetration rates and chemical/mechanical
stability are needed for the quick development. For these reasons, the
synthesis of a composite polymeric membrane and its development studies
constitute the basis of this context. In recent decades, chitosan, a relatively
inert biomaterial with the ability to form films, has gained quick recognition
for its potential in separation and purification technology. Chitosan membranes
have emerged as a potential option for a number of applications due to their
hydrophilicity, biocompatibility, simplicity of modification, and exceptional
affinity for dyes, metals and proteins S-RGO (sulfurized reduced
graphene oxide), was added to the structure in order to increase porosity,
surface area as well as electron and proton conductivity. S-RGO was
synthesized as previously described in literature. Chitosan
and gelatin solutions were blended at different volumetric ratios and different
amounts of S-RGO was added in order to introduce sulfonic acid groups as well
as obtaining a layered structure. The membranes
were oven dried at 40°C for 1 day. The effect of various parameters were
investigated i.e the blending ratio of the polymers, amount and type of
inorganic fillers, synthesis conditions. The
produced membranes were examined for structural integrity, crystallinity,
morphology, and thermal stability using SEM, FTIR, XRD, and TGA. In addition to
these analyses, some more analyses such as electrochemical impedance
spectroscopy (EIS), swelling and water uptake analyses was carried out. This
work will ultimately contribute to the growing field of green materials science
by highlighting a bio-based approach for advanced manufacturing methods in membrane
development.
