Latest Patents

Coffey's latest patents showcase his innovative approach to solving complex problems. One of his notable inventions is related to functional fluoropolymers. This invention involves novel linear, semi-crystalline, functional fluoropolymers obtained by copolymerizing a fluorinated vinylic monomer with a hydrophilic monomer. The selection of hydrophilic monomers includes vinyl alkyl acids, vinyl phosphonates, functional acrylamides, carbonates, vinyl ethers, alkoxy compounds, and double hydrophilic group monomers.

Another significant patent is for a lithium-ion battery separator. This invention pertains to a separator for non-aqueous-type electrochemical devices, which is coated with a polymer binder composition containing polymer particles of two different sizes. One fraction of the polymer particles has a weight average particle size of less than 1.5 microns, while the other fraction exceeds 1.5 microns. This bi-modal polymer coating creates an uneven surface that allows for the expansion of battery components during charging and discharging cycles, without increasing the overall size of the battery.
