Abstract
The more recent research activity of the Irradiated Polymers team focused mainly on nanostructures membranes for nanofiltration and nanofluidic systems in biomedical and energy fields. The so called track-etched membranes were made by chemical revealing of tracks induced from swift heavy ions irradiations in collaboration with the CIRIL laboratory (GANIL, France). The background experience of the tem about electron-polymer interaction allowed us to predict the behavior of the radio-induced grafting, namely radografting, inside ion-tracks. It was the necessary to adapt our detection tools to chemical modification of picomole range and to nanometer scale architecture of these membranes. Consequently, we resorted to the use of high-cost techniques such as small angle neutron scattering to be able to characterize accurately polymer membrane nanopores. In parallel, more accessible techniques like gas permeation have been developed for a rapid evaluation of nanopore radii. The labeling of introduced chemical functionalities with fluorescent probes was a very effective mean to visualize very few amounts of molecules by confocal microscopy and to localize, for the first time, the radiografting inside theetched tracks. The study of such nanostructures has enlarged our perspectives and collaborations. Indeed, it pushed us to electrodeposite metallic nanowires and to create conductive polymer nanotubes
