Project description:

Today, the field of synthetic and biological polymers is impacting extensively various areas of chemistry, biochemistry, molecular biology, nanotechnology, electronics, medicine, life sciences, materials etc. Synthetic polymers have played a fascinating role in the successful development of biomedical devices and drug delivery systems.

 

Phosphorus-containing materials can be employed for a wide range of technological applications. For instance, they were largely used in industry due to the bind metals ability. Organophosphonates exhibited interesting complexing properties and were used as dispersants, corrosion inhibiting agent, or for preventing deposit formation. The necessity of new high performance materials based on polymers makes important the scientific research in order to satisfy more important needs: flame retardancy and minimization environmentalimpacts.

 

Recently, the interest of phosphorus-based materials (polyphosphates, polyphosphonates, polyphosphoesters, phosphonated poly(meth)acrylates, polyphosphazene etc.) used in the biomedical field is accelerating because they proved to be biodegradable and blood compatible, showed reduced protein adsorption, and led to strong interactions with dentin, enamel, or bones. As consequence, they appear as an interesting class of materials, which will lead to further developments in this field of applications.

 

The main goal of the present project is to develop new structures which will be highly recommended for applications in top fields of modern technology and nanotechnology (electronics and optoelectronics) as well as in biomedicine (biosensors, drug controlled release, tissue engineering), materials containing phosphorus in the main and/or side chain. The structure of these polymers will be designed in such manner in order to lead to products with high thermal stability, characteristic to rigid aromatic units, good solubility, good range between thermal transition and decomposition temperatures, film forming ability, characteristic to flexible units, and a series of specific properties such as: exceptional physico-mechanical properties, liquid crystalline behavior, optical properties, flame resistance, biodegradability, biocompatibility etc.
