Annotation: | The proposed project is focused on the development of new generation of organo-modified clay minerals using poly(2-alkenyl-2-oxazolines) as representatives of non-ionic, but still highly polar polymers. We expect that organo-modification of montmorillonites using this type of polymers will lead to organoclay materials with more efficient intercalation and thus, with higher adsorption efficiency toward various hazardous organic molecules. The presence of poly(2-alkenyl-2-oxazolines) and poly(2-alkenyl-2-oxazines) in the gallery of clay minerals will ensure catalytic decomposition of hazardous organic molecules. In our case, we use for the evaluation of adsorption and hydrolytic decomposition organophosphate as organic compounds widely used as pesticides and they habe been already used as chemical warfare agents. The combination of improved adsorption and accelerated hydrolytic decomposition of studied organophosphates represents the main innovative aspect of the project and pave an avenue to montmorillonite-based nanoreactors for dephosphorylation reactions of neurotoxic organophosphate agents. Here, we present metal-free catalytic systems that are potentially usable for human and environmental protection. Moreover, poly(2-alkenyl-2-oxazolines) and poly(2-alkenyl-2-oxazines) represent new groups of polymers with reactive pendant 2-oxazoline and 2-oxazine groups, respectively, capable to provide post-polymerization reactions with carboxylic groups. In our case, 2-oxazoline groups will be used for the structural stabilization during melt mixing with carboxylic units containing polymer matrices. |

Program: | VEGA |
Project leader: | Ing. Pálková Helena, PhD. |
Annotation: | The project is aimed at the preparation of composite materials based on layered aluminosilicates as suitablecarriers for different types of organic polycations, possessing properties interesting for various applications. Thevariability in the chemical composition of the selected layered materials in connection with the diversity of themolecular structures and properties of polymeric cations and copolymers opens up wide opportunities towardsthe preparation of well-defined systems. Careful selection of the inorganic carries and polycations is an essentialstep to achieve their mutual compatibility resulting not only in preserving but primarily in improving the keyproperties of the prepared composites. Therefore, the synthesis conditions (e.g. pH) and the addition of anothercomponent to the systems (fluorescent dyes, metal nanoparticles) will be evaluated. The cytotoxicity test topredict biocompatibility of the materials, photoactivity, catalytic and adsorption efficiency will be assessed as well. |
