NOVELTY - Producing bone induction regeneration shielding film, comprises (a) preparing coating solution containing graphene oxide that promotes bone differentiation, (b) cleaning a shielding film main body, and (c) forming a coating layer on the shielding film main body having a base of the shielding film by using the coating solution. The step (b) comprises submerging the shielding film main body into piranha solution, and rinsing the shielding film main body with deionized water. USE - The method is useful for producing bone induction regeneration shielding film (claimed). ADVANTAGE - The film promotes bone induction regeneration, and increases efficiency of guided bone and tissue regeneration. The method shortens production time. DETAILED DESCRIPTION - Producing bone induction regeneration shielding film, comprises (a) preparing coating solution containing graphene oxide that promotes bone differentiation, (b) cleaning a shielding film main body, and (c) forming a coating layer on the shielding film main body having a base of the shielding film by using the coating solution. The step (b) comprises submerging the shielding film main body into piranha solution, and rinsing the shielding film main body with deionized water. The step (c) comprises positioning a deposition substrate for dragging the coating solution so as to have an acute angle of 25-35 degrees with respect to the shielding film main body, applying the coating solution between the shielding film main body and the deposition substrate at an acute angle to form a meniscus in the acute angle, dragging the deposition substrate in one direction so that the coating solution is coated on the surface of the shielding film main body, dragging the deposition substrate in the other direction so that the coating solution is coated on the surface of the shielding film main body, and repeating the one-direction dragging step and the other-direction dragging steps.
