Films minces de copolymères à blocs supramoléculaires et photosensibles
Grosrenaud, Josué (2016-03-23)La technique de trempage («dip-coating») est un procédé rapide et efficace pour former des films minces de copolymères à blocs (CPB) d’épaisseur et de nano-morphologies variées. Très peu d’études ont toutefois porté sur le trempage des CPB supramoléculaires ... -
In situ photocontrol of block copolymer morphology during dip-coating of thin films
Vapaavuori, Jaana; Grosrenaud, Josué; Pellerin, Christian; Bazuin, Geraldine (American Chemical Society, 2015-09-28)We demonstrate a unique combination of simultaneous top-down and bottom-up control of the morphology of block copolymer films by application of in situ optical irradiation during dip-coating. A light-addressable and block-selective small molecule, ... -
Photocontrol of supramolecular azo-containing block copolymer thin films during dip-coating : toward nanoscale patterned coatings
Vapaavuori, Jaana; Grosrenaud, Josué; Siiskonen, Antti; Pellerin, Christian; Bazuin, Geraldine (American Chemical Society, 2019-05-07)Dip-coating allows nanostructured block copolymer (BCP) thin film fabrication in a fast and facile one-step process. It can also be coupled with external controls, such as illumination. Herein, we expose several design principles that enable photocontrol ...
