Spontaneous rolling is triggered in micrometric PDMS based bilayer thin films by exposure to solvent vapors. First, the influence of the process parameters are investigated. Second, before rolling, the surface can be patterned (chemically, topograph-ically), permitting the fabrication of inexpensive fully functionalized capillaries. %G English %2 https://cea.hal.science/cea-02351501/document %2 https://cea.hal.science/cea-02351501/file/Malloggi_MicroTAS_2016.pdf %L cea-02351501 %U https://cea.hal.science/cea-02351501 %~ CEA %~ CNRS %~ UNIV-STRASBG %~ PUBNIMBE %~ INC-CNRS %~ IRAMIS-NIMBE %~ CEA-UPSAY %~ UNIV-PARIS-SACLAY %~ CEA-UPSAY-SACLAY %~ SITE-ALSACE %~ ANR %~ GS-ENGINEERING %~ IRAMIS %~ GS-CHIMIE %~ GS-PHYSIQUE %~ INSTITUT-SCIENCES-LUMIERE %~ TEST2-HALCNRS %~ LABORATOIRES-UHA %~ UHA %~ IS2M
