Latest Patents

Bamba's latest patents include innovative methods for producing porous polyether sulfone films and porous polyimide films. The first patent describes a porous polyether sulfone film that features macrovoids and excellent dimensional stability. This film consists of a surface layer (a), a surface layer (b), and a macrovoid layer interposed between them. The macrovoid layer is characterized by partition walls that connect to the surface layers, creating a structure with multiple macrovoids. The surface layers are designed with pores that connect to these macrovoids, enhancing the film's functionality.

The second patent focuses on a method for producing porous polyimide films. This method involves casting a poly(amic acid) solution and immersing it in a coagulating solvent. The resulting porous film undergoes heat treatment and imidization, ensuring minimal shrinkage during the process. This innovative approach allows for a controlled temperature increase during heat treatment, which is crucial for maintaining the film's integrity.
