Organic-inorganic hybrid polymers and nanocomposites.

Polymer nanocomposites have been the subject of intense research in the field of materials science during recent years due to their promise of unprecedented performance, design flexibility, and a combination of properties from both parts thus leading to novel and functional materials. In the work by P. Dallas et al., a newly developed cornetlike polymer from the reaction of phosphonitnlic chloride and 1,4-phenylenediamine is used as both a reductant and matrix for the synthesis of silver nanopartides that are attached on its surface. The ultrasmall nanoparticles are bonded on the surface after reduction of silver nitrate by the amine units and inherit the composite with extraordinary antimicrobial activity in various bacterial strains and yeasts. Due to its unique morphology, anion exchange properties, reduction ability, and tunable optical absorption properties, this hybrid polymer is a strong candidate for the construction of new functional nanocomposites.
