Abstract: Described are techniques for making aluminum alloy products and methods for pre-treating aluminum alloys with small molecules, and the resultant aluminum alloy products, in which small molecules including phosphorus-containing organic acid functionality, such as organo-phos-phonic acids, are applied to a surface of an aluminum alloy product to generate a self-assembled monolayer or multilayer of small molecules on the surface of the aluminum alloy product. Mixtures of different phosphorus-containing organic acids may be employed. At least some of the phospho-ms-containing organic acids may exhibit a hydrophilic character, such as by including one or more hydrophilic functional groups. The self-assembled monolayer or multilayer including hydrophilic functionality may advantageously allow the aluminum alloy product to have a good wettability by water and other hydrophilic substances, such as some epoxy adhesives, but also to have a good wet-tability by hydrophobic substances, such as some lubricants.

Abstract: Described herein are graft copolymer pretreatment compositions that impart improved corrosion resistance, enhanced adhesion performance, lubrication, improved coating performance (e.g., enhanced wettability), and/or improved weldability and/or weld durability to metals (e.g., aluminum alloys) as compared to non-pretreated metal surfaces. Also provided herein are aluminum alloys coated with the disclosed graft copolymer pretreatment compositions and methods for applying the disclosed graft copolymer pretreatment compositions to aluminum alloys.

Abstract: Various blends of polymers are disclosed, comprising oligopeptide functionalised polymers such as polyisobutylene and polystyrene. Mono-functionalised and di-functionalised polymers (each containing 0 to 5 peptide units beyond its terminal amide group) may be blended with each other and/or with non-functionalised polymers to produce blended compositions. Such compositions are of use, for example, in vibrations dampers. Certain blends also exhibit self-healing properties.
