Title (EN) CYLINDRICAL TUBE WHOSE INNER WALL IS CONSTITUTED BY A HYDROPHOBIC COATING
(FR) TUBE CYLINDRIQUE DONT LA PAROI INTERNE EST CONSTITUÉE PAR UN REVÊTEMENT HYDROPHOBE
Abstract:
(EN) The invention relates to a cylindrical tube made of polymer material or glass, whose cylindrical inner wall includes a coating of hydrophobic particles having a surface with a peak-to-valley distance of between 100 nm and 50 μm; a process for manufacturing said tube by forming a coating on its inner wall including the steps of displacing a segment of a liquid composition of suspended coating particles within the tube at a constant controlled velocity of at least 2 cm/sec so as to drive a homogeneous liquid film on the inner wall of the tube, letting the solvent of the liquid composition evaporate and the suspended coating particles deposit on the inner wall of the tube, optionally, repeating the two previous steps at least once.
(FR) L'invention concerne un tube cylindrique en matériau polymère ou en verre, dont la paroi interne cylindrique comprend un revêtement de particules hydrophobes pourvues d'une surface présentant une distance pic-vallée entre 100 nm et 50 µm ; un procédé de fabrication dudit tube par formation d'un revêtement sur sa paroi interne comprenant les étapes consistant à : déplacer un segment d'une composition liquide de particules de revêtement en suspension à l'intérieur du tube à une vitesse régulée constante d'au moins 2 cm/sec de manière à entraîner un film liquide homogène sur la paroi interne du tube, laisser le solvant de la composition liquide s'évaporer et les particules de revêtement en suspension se déposer sur la paroi interne du tube, éventuellement, répéter au moins une fois les deux étapes précédentes.
