Project summary
The proposed project entitled “Polymer coated ordered mesoporous carbons
with multifunctional properties” will be developed in Institute of excellence
of the Romanian Academy by a team formed from the project leader and a
tutor with complementarily expertise required for the project development,
e.g. mesoporous carbons and polymer science, respectively. The aim of this
research project is to prepare polymer-coverd ordered mesoporous carbon
materials with high adsorption properties, appropriate for decontamination
of industrial water and haemoperfusion. The project is organized in three
research phases dealing, respectively, with (a) the preparation of
mesoporous nanoparticles; (b) functionalisation of the particle by chemical
treatment and polymer coating; (c) characterization of structure, physicochemical and the sorption properties of the functional particles. Expected
results: three ISI papers; six conference presentations.
Project objectives
•
- To establish a reproducible method for the synthesis of highly
ordered mesoporous carbons with designed architecture and
showing high sorption properties;
•
- To provide a treatment method affording high functionality
(surface reactivity and wettability) of the pore surfaces;
•
- To optimize the preparation conditions of polymer-carbon
systems in order to minimize the particle agglomeration and to
maintain appropriate porosity;
•
- To establish preparation-structure-properties correlations and
to check the end use properties of the optimized materials.

The obtained results showed that the
adsorption
capacity
obtained
for
PNiPAM-functionalized
mesoporous
carbon (80%) is greater than the vitamin
B2 adsorption on pristine mesoporous
carbon (53%). These results show that
the PNiPAM-functionalized mesoporous
carbon

favorably
with
unfunctionalized mesoporous carbon
