• Hollow Fiber Membrane and Preparing Method Thereof

  The present invention relates to a polyvinylidene difluoride hollow fiber membrane and a method of preparing the same, and more particularly, to an improved polyvinylidene difluoride hollow fiber membrane and a preparation method thereof, in which a spinning solution consisting of polyvinylidene fluoride, alcohol dendrimer and organic solvent is prepared, and then is subjected to solidification by a wet-phase transition process, cleaning and drying, in which alcohol dendrimer that is an organic material as a pore former is introduced, allowing uniform disperse of alcohol dendrimer in polyvinylidene difluoride to form pores, with each having a high dispersion ability and a uniform size, and in which an excellent adhesion durability is imparted, owing to the use of a single material of polyvinylidene difluoride, unlike the conventional hollow fiber membrane preparation method in which pores are formed using existing inorganic particles.
