Abstract: The present invention discloses a method for forming a composite membrane with a porous coating layer. At first, a filling process is carried out to fill the pores of a porous substrate with a liquid. Next, a raw material is transformed into melt or incomplete melt droplets by a heating source and the droplets are sprayed to the surface of the porous substrate filled with the liquid. The liquid is evaporated by the high temperature droplets and plasma flame to become vapor and the vapor breaks through the droplets to have the droplets sputter into different blocks to thereby form random and dispersed flat particles after cooled. Flat particles are formed and stacked continuously so as to form a composite membrane with a porous coating layer. Moreover, the invention provides an apparatus for forming a composite membrane with a porous coating layer.
