Title
(EN) CALCITE CHANNEL STRUCTURES WITH HETEROGENEOUS WETTABILITY
(FR) STRUCTURES DE CANAUX DE CALCITE À MOUILLABILITÉ HÉTÉROGÈNE
Abstract
(EN)
A method of making a portion of a microfluidic channel includes lithographically patterning a first pattern (100) into a first layer of photoresist (112) disposed on a substrate (110), the first pattern representative of morphology of a reservoir rock; etching the first pattern into the substrate to form a patterned substrate (118); disposing a second layer of photoresist (120) onto the patterned substrate; lithographically patterning a second pattern (123) into the second layer of photoresist to reveal portions of the patterned substrate; and depositing calcite (132) onto the exposed portions of the patterned substrate; and corresponding microfluidic device (300).
(FR)
La présente invention concerne un procédé de fabrication d'une partie d'un canal microfluidique qui comprend la formation lithographique d'un premier motif (100) dans une première couche de résine photosensible (112) disposée sur un substrat (110), le premier motif représentant la morphologie d'une roche de réservoir ; la gravure du premier motif dans le substrat pour former un substrat à motifs (118) ; la disposition d'une seconde couche de résine photosensible (120) sur le substrat à motifs ; la formation lithographique d'un second motif (123) dans la seconde couche de résine photosensible pour révéler des parties du substrat à motifs ; et le dépôt de calcite (132) sur les parties exposées du substrat à motifs ; et un dispositif microfluidique correspondant (300).
