π-conjugated polyelectrolyte (CPE) foams for new application opportunities

The highly porous structures with porosities up to 95 %, low densities (< 0.1 g / cm3) and surface areas exceeding 500 m2/g are properties that distinguish our semiconducting π-conjugated polyelectrolyte (CPE) foams. Combination of such 3D-interconnected macroporous morphology and the photoactive π-electron backbone hold a great promise in the semiconductor-mediated heterogeneous photocatalysis.


They represent "smart" materials with properties that attract an increasing level of interest in a large number of applications, especially in heterogeneous photocatalysis e.g. degrading aquatic, atmospheric or microbial contaminants.

Main advantages

Our π-conjugated (polyelectrolyte) foams can be custom-made according to the wishes of the customer in various forms such as beads, monoliths or monolithic columns having either cauliflower or 3D interconnected macroporous morphologies. Most important, these foams possess two important features in a single functional material: π-conjugated backbone (providing organic semiconducting properties) and water-soluble ionic side chains (providing necessary hydrophilicity). Water-soluble ionic side chains make π-conjugated polyelectrolyte foams as a hydrophilic material and, thus, applicable in water-borne systems as opposed to the typically hydrophobic π-conjugated polymers.
