Latest Patents

One of his latest patents is titled "Isoporous self-assembled block copolymer films containing high molecular weight hydrophilic additives and methods of making the same." This invention provides systems and methods for substantially improving the compaction resistance of isoporous block copolymer (BCP) film by adding a high molecular weight hydrophilic additive in the casting dope formulation. The systems and methods disclosed also enhance film properties, including low fouling propensity, improved permeability, and the ability to tune the substructure and pore size of these novel BCP films. These porous BCP films are particularly useful in filtration and separations applications and are amenable to standard manufacturing practices.

Another significant patent is "Isoporous mesoporous asymmetric block copolymer materials with macrovoids and method of making the same." This invention includes a mesoporous isoporous asymmetric material that comprises at least one diblock or multiblock copolymer. The material features a transition layer with a thickness of at least 300 nm and a low macrovoid density, along with a sub-structure that has a high macrovoid density. The method for producing these materials involves dissolving the copolymer in a solution, dispensing it onto a substrate, and exposing it to a nonsolvent to cause precipitation.
