Latest Patents

One of his latest patents is titled "Ionic polymers containing spiro structure and preparation method and application thereof." This invention introduces ionic polymers featuring a spiro structure, which enhances the solubility and gas permeability of the ionic polymer while maintaining excellent conductivity, mechanical properties, and dimensional stability. The incorporation of a spiro fragment with a large free volume into the polymer backbone results in improved gas permeability of the catalyst layer prepared from this ionic polymer, making it suitable as a catalyst binder for proton exchange membrane fuel cells (PEMFCs) or anion exchange membrane fuel cells (AEMFCs). Furthermore, the electrochemical performance of the fuel cell is enhanced. Additionally, the proton exchange membrane and anion exchange membrane derived from this ionic polymer effectively improve the conductivity of both types of membranes by increasing the space volume due to the presence of the large free volume spiro fragment.

Another notable patent is "Highly alkali-stable cationic polymers and their preparation methods and applications." This invention discloses a preparation method for highly alkali-stable cationic polymers, which involves placing a polymerization mixture comprising 1-R1-3-piperidinone or its salts and arene monomers in a first organic solvent. The process includes catalytic polycondensation by adding organic strong acids, resulting in a polymer dispersion with piperidine moieties. The cationic polymers prepared through this method exhibit outstanding alkaline stability, making them suitable for applications such as anion exchange membranes and catalyst layer binders.
