Abstract: 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.

Abstract: The invention relates to a method for forming a coating in the inner wall of a tube, including the following operations: moving a segment of a liquid composition of coating particles in suspension inside the tube at a constant controlled speed at least equal to 2 cm/s, so as to drive a homogeneous liquid film over the inner wall of the tube, and allowing the solvent of the liquid composition to evaporate and the coating particles in suspension to be deposited on the inner wall of the tube.
