Latest Patents
Rigby's latest patents include innovative technologies related to anodic aluminium oxide membranes. One of his patents describes a porous anodic aluminum oxide membrane, which features a profiled surface on a scale of 0.01 to 50 mm. This membrane can be created by profiling an aluminium metal substrate, anodizing it to form a porous membrane, and then separating the membrane from the substrate. The design allows for the construction of structures with interesting properties as filters by bonding several membranes along the crests of the ribs.
Another significant patent involves the creation of porous anodic aluminium oxide films. This invention provides a film with a major face area of at least 50 cm², containing phosphorus derived from the anodizing electrolyte. The film is preferably at least 5 microns thick, with pores spaced 0.1-0.5 microns apart. The anodizing process utilizes an electrolyte based on phosphoric acid, maintained at specific concentrations and temperatures, to achieve the desired properties for filtration applications.
