Abstract: A method of applying a riblet structure coating on the internal surface of a pipe includes coating the internal surface of a pipe with a resin layer and applying a cavity mold having a reverse riblet pattern structure to the coated internal surface of the pipe. A flexible air bag is inserted into the interior of the pipe and charged with air to hold the mold against the coated internal surface of the pipe. The air bag may be charged with air for a sufficient amount of time to allow the coating to cure in the riblet shape of the mold. Afterwards, the air bag and the mold are removed from the pipe to yield a pipe coated with an internal riblet structure.

Abstract: The present invention provides an adhesive material with improved bonding performance to a wet substrate, the adhesive material includes a first component selected from a polysiloxane-based adhesive, or a polyurethane-based adhesive; and a second component of a catechol-containing polymeric additive which includes a reaction product of polyvinylpyrrolidone with 3′,4′-dihydroxy-2-chloroacetophenone, and the weight ratio of polyvinylpyrrolidone to 3′,4′-dihydroxy-2-chloroacetophenone ranging from 10:1 to 1:1. The adhesive material being a mixture of at least the first component and the second component, where the second component is approximately 1 wt. % to 10 wt. % of the first component.

Abstract: A durable, hydrophobic and anti-scratching nano-coating for coating on a glass substrate or surface having a water contact angle of about 90° or more, a reduced coefficient of friction by 50% or more, and a reduced surface roughness compared to those of the glass substrate or surface without the nano-coating is provided, which includes a layer of fluorinated silica derived from sol-gel hydrolysis between one or more tetraalkoxysilanes having at least three alkoxy groups and one or more polyfluorinated silanes having at least a trialkoxysilane and from 15 to 17 fluorine atoms in the presence of a catalyst to a reaction mixture of the sol-gel hydrolysis between the one or more tetraalkoxysilanes and the one or more polyfluorinated silanes, and a solvent. A related method of fabricating the nano-coating via atomization of acid-containing or alkali-containing solution and sol-gel precursor solution onto the glass surface is also provided.

Abstract: The present invention provides a one-component silicone sealant composition curable when exposed to moisture at room temperature. The resulting silicone sealant has excellent stain-resistance, good overall mechanical performances and good adhesion on both dry and wet substrates. The composition contains modified hydroxyl-terminated polyorganosiloxanes polymer network in different viscosities being cross-linked with branched silicone oil in the presence of an environmental-friendly and tin-free catalyst and cross-linkers while some inert and/or functional nanofillers are added into the composition to provide mechanical and/or functional properties to the resulting silicone sealant. A method for preparing the present composition is also provided.
