Latest Patents

Yangyan Qi holds a patent for a "Preparation method for nanocomposite fiber membrane material based on bio-based liquefied formaldehyde resin." This patent describes a method that utilizes a bio-based raw material processed through a phenol/polyethylene glycol complex liquefaction process. The process involves divalent alkali metal hydroxide high ortho-position induction synthesis resinification and modification with polyvinyl alcohol to create a spinnable precursor known as PVA-BLF. A coaxial electrospinning device is then employed, where PVA-BLF serves as the core layer and a titanium dioxide dispersion acts as the shell layer. The resulting PVA-BLF/TiO2 nanocomposite fiber membrane material exhibits an average diameter of 150-450 nm, a specific surface area of 500-700 m/g, and a porosity exceeding 60%. The material demonstrates excellent filtration and regeneration performance, making it suitable for applications in water and air purification.
