摘要:
Superoleophilic particles and surfaces and methods of making the same are described. The superoleophilic particles can include porous particles having a hydrophobic coating layer deposited thereon. The coated porous particles are characterized by particle sizes ranging from at least 100 nm to about 10 μm and a plurality of nanopores. Some of the nanopores provide flow through porosity. The superoleophilic particles also include oil pinned within the nanopores of the porous particles The plurality of porous particles can include (i) particles including a plurality of spaced apart nanostructured features comprising a contiguous, protrusive material, (ii) diatomaceous earth particles, or (iii) both. The surfaces can include the superoleophilic particles coupled to the surface.
摘要:
The present invention relates to blends of encapsulated biocides with free biocides. In particular, the present invention relates to blends of encapsulated 4,5-dichloro-2-n-octyl-3(2H)-isothiazolone (“DCOIT”) with free biocides. The invention also relates to marine antifouling coatings and paints incorporating free biocides and encapsulated DCOIT, and using the free biocides and encapsulated DCOIT in marine antifouling coatings and paints.
摘要:
The invention relates to new dispersions, especially for underwater paints, containing (a) a microencapsulated anti-fouling component and (b) an organic solvent.
摘要:
The present invention provides a microorganism which, when an underwater structure is formed with a coating film containing it, produces a biojelly in water to prevent fouling of the structure with macroscopic aquatic life, such a coating or a coating film, and a method of preventing attachment of macroscopic aquatic life which comprises using said coating or coating film. The present invention is directed to a strain of microorganism belonging to the genus Alteromonas and having the ability to produce a biojelly.
摘要:
A natural composition for preventing the growth of barnacles, grass, worms and the like on the hull of a boat or ship. The natural, powdered crustacean shell-based composition makes it easy to remove slime and scum formation and is safe to use on all boats or ships, including aluminum and steel. The natural composition incorporates pulverized, powdered, complete crustacean shells as the active ingredient, namely powdered mussel shells or the like.
摘要:
A device and method for preventing zooglea growth in an air conditioning system or on one or more components of the air conditioning system is described. The device includes cordage having an antifouling coating made from a polymer infused with metallic particles. The method can include applying the antifouling coating to cordage and inserting the cordage through a condensate pipe of the air conditioning system. The method can include applying the antifouling coating to one or more components of the air conditioning system, including a drainpipe, drain pan, or fitting, and installing the one or more components in the air conditioning system.
摘要:
An antimicrobial formulation that can be directly added into a composition or onto a surface of a composition (e.g., forming a surface coating on a composition or device). The antimicrobial formulation includes sodium pentaborate, di-sodium tetraborate decahydrate, titanium diborite, titanium borate, sodium pyrithione, zinc pyrithione, benzhetonium chloride, or any combination thereof.
摘要:
According to one or more embodiments, an antifouling material may be produced by forming a nanostructured mold, where a liquid mold precursor is contacted with a textured surface of a nanostructured template, the liquid mold precursor is solidified to the nanostructured template, and the formed nanostructured mold is removed from the nanostructured template. The antifouling material may be formed by contacting a liquid precursor mixture with a textured surface of the nanostructured mold, solidifying the liquid precursor mixture onto the nanostructured mold, and removing the formed antifouling material from the nanostructured mold. The antifouling material may include a nanostructured surface and may further include a toxin.
摘要:
Coating a metallic surface with at least one of a pretreatment composition prior to organic coating, with a passivation composition without intent for subsequent organic coating, with a pretreatment primer composition, with a primer composition, with a paint composition and with an electrocoating composition, wherein the coating composition includes particles on a base of at least one layered double hydroxide (LDH) phase characterized by the general formula [M2+(1±0.5)−x(M3+, M4+)x(OH)2±0.75]An−x/n.mH2O.
