Latest Patents
One of Seog O Yoo's key patents is titled "Two-stage process for preparing aromatic polyamide film." This patent describes a process where an aromatic diamine and an aromatic diacid chloride are dissolved in an amide polymerization solvent containing an inorganic salt. The method involves partial polymerization at low temperatures to create an optically anisotropic liquid crystalline prepolymer dope. This prepolymer is then extruded through a film die under a draw ratio or subjected to shear, followed by contact with a second solvent that accelerates polymerization and precipitation. The result is an aromatic polyamide film that is free of crystal defect layers perpendicular to the film axis, exhibiting high strength and a high degree of molecular orientation. Seog O Yoo holds 1 patent in this area.
