Architectures of molecular rods in a polymer network

Cel

The present project is dedicated to a systematic experimental and theoretical investigation of equilibrium and dynamic characteristics of polymer gels with entrapped linear rod like macromolecules capable to self-organization. The main aims of the project are:
1) to prepare new types of composite hydrogels consisting of flexible polyacrylamide network loaded with newly synthesized rodlike linear polyelectrolytes, which are capable to self-assembly in aqueous media due to hydrophobic character of their main chain;
2) to study the effect of rodlike macromolecules on the strengthening of highly swollen gel which is promising for the application of gels as superabsorbents;
3) to study the self-aggregation of rodlike macromolecules inside the gel, including the liquid-crystalline ordering, a particular attention being paid to the possibility of regulation of the emerging microstructures by external stimuli exploiting the responsive properties of the gels;
4) to study the dynamics of entrapped macromolecules inside the network to obtain information about the self-assembly of the macromolecules and their interaction with network chains.

Along with traditional investigation of equilibrium characteristics of the gels with embedded macromolecules, a particular attention will be paid to the study of molecular dynamics in the system. The theoretical approaches will be developed to describe the equilibrium and dynamic properties of gels loaded with linear rodlike macromolecules.

Six research teams (two from INTAS members and four from Russia) will be involved in the project. Different experimental techniques (small-angle neutron scattering, quasi-elastic light scattering, pulsed field gradient nuclear magnetic resonance, polarization microscopy) will be used.

These studies will permit to better understand a correlation of the macroscopic properties of the composite gels with their microstructures, which is important in the unfolding of numerous practical applications of these gels.
