| 摘要 |
The invention provides materials and methods for forming coatings on substrates. The coatings are durable and resistant to damage from environmental, chemical, thermal, and/or radiative sources. In some embodiments, the coatings comprise bilayers of electrostatically charged materials. The bilayers are created by alternately applying solutions comprising water-soluble, electrostatically charged materials. Durability is imparted to the coatings by the formation of crosslinks that are formed within and between layers after deposition of the coatings. |

1. A method for coating a surface, the method comprising
(a) depositing a layer of a first material comprising first reversible bonding moieties and first crosslinkable moieties on the surface, said first crosslinkable moieties being selected from the group consisting of vinyl, alkenes, alkenes, acrylates, methacrylates, hydrolysable silanes or oligomers thereof, titanates, epoxy, alkoxides, metal alkoxy precursors, phosphonates, and combinations thereof; and (b) depositing a layer of a second material comprising second reversible bonding moieties on the surface, wherein the second reversible bonding moieties are complementary to the first reversible bonding moieties and are capable of forming a reversible chemical bond, and wherein the first material and the second material form a bilayer; and (c) optionally depositing one or more additional bilayers on the surface; wherein said first material and said second material are bonded by one or more of:
(1) ionic attractive forces;(2) hydrogen bonding attractive forces; and(3) covalent bonding. |
