The coating includes: a layer of epoxy resin (2) having free hydroxyl groups, which are applied directly to the inside (1a) of the metallic pipe (1); a layer of thermoplastic adhesive (3) applied directly onto the layer of epoxy resin; and a layer of a plastic material (4) containing polyvinylidene fluoride or polyvinylidene difluoride (PVDF).

The present invention provides an air exhaust or air-and-smoke exhaust pipe for a clean room and a manufacturing method thereof. The air exhaust or air-and-smoke exhaust pipe is a pipe that satisfies FM4922, FM4910, or another equivalent standard and that is used for exhausting nonflammable chemical gas and corrosive vapor or nonflammable chemical gas, corrosive vapor and smoke in fire. The manufacturing method for the air exhaust or air-and-smoke exhaust pipe is: coating an inner part of a pre-manufactured metal pipe with a liquid coating that can be initially dried at normal temperature or low temperature to obtain an inner coating pipe; and baking the inner coating pipe at a temperature not exceeding 250 C. after the coating is initially dried, thus the coating is completely dried to obtain a finished product.

In one or more embodiments, the present invention provides a method of applying or printing structural colors to a substrate that involves pre-treatment of the substrate surface to prevent absorption of the fluid containing the particles. This allows the fluid to maintain their sessile drop shapes and as the water evaporates, the colloidal particles spontaneously assemble within the confined geometry into semi-ordered structures that interact with light to produce structural color. While the pre-treatment may be done in a variety of ways, application of a, hydrophobic and/or oleophobic coating, like 1H-IH,2H-perfluoro-1-dodecene (C.sub.10F.sub.21CHCH.sub.2) (perfluoro) monomer, fluoroalkyls, fluorohydroalkyls, cyclo-fluoroalkyls, fluorobenzen, by plasma-enhanced chemical vapor deposition (cold plasma treatment) has been found to be effective, particularly for printing applications. These treated substrates allow production of a wide range of structural colors using binary systems of nanoparticles.
