Project summaryThe 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,
physico-chemical and the sorption properties of the functional
particles. Expected results: three ISI papers; six conference
presentations.
-
- 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.Project objectives

Project planed activities
-
Project selected results2013 synthesis of ordered mesoporous
carbon Ordered mesoporous carbon materials were obtained by
template synthesis using SBA-15 silica template and glycerol as
carbon precursor.

Project selected results2014 preliminary application test 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
compare favorably with unfunctionalized mesoporous carbon
-
Project selected results2015 sorption tests of creatinine on
PNiPAM-functionalized ordered mesoporous carbon materials The
obtained results showed that the adsorption capacity obtained for
PNiPAM-functionalized mesoporous carbon (460 mg/g) is greater than
that of pristine mesoporous carbon (390 mg/g). These results show
that the PNiPAM-functionalized mesoporous carbon are good candidate
for haemofiltration

-
Project selected results2015 sorptive properties tests on
mesoporous carbon material coated with chitosan A comparative study
have been done, focusing on ordered mesoporous carbon materials
coated with chitosan and chitosan-coated ferrite. Due to the
greater textural properties of ordered mesoporous carbon materials,
the best sorption capacity for Cr(III) ions has been obtained.
