Zusammenfassung:	Disclosed are a manufacturing method for an electromagnetic wave shielding material and an electromagnetic wave shielding material manufactured thereby. In one embodiment, the manufacturing method for an electromagnetic wave shielding material includes a step of forming a coating layer on the surface of a polymer foam by using a first composition. The polymer foam includes at least one of polyolefin and polystyrene. The first composition includes 100 parts by weight of a solvent, 0.1 to 10 parts by weight of carbon nanotubes, and 1 to 20 parts by weight of a phosphorus-based compound. The phosphorus-based compound includes ammonium phosphate and nitrilotris(methylenephosphonic acid) ammonium salt. 전파 차폐재 제조방법 및 이에 의해 제조된 전파 차폐재에 관한 발명이 개시된다. 일 구체예에서 상기 전파 차폐재 제조방법은 폴리머 발포체의 표면에 제1 조성물을 이용하여 코팅층을 형성하는 단계;를 포함하며, 상기 폴리머 발포체는 폴리올레핀 및 폴리스티렌 중 하나 이상을 포함하며, 상기 제1 조성물은 용제 100 중량부, 탄소나노튜브 0.1~10 중량부 및 인계 화합물 1~20 중량부를 포함하고, 상기 인계 화합물은 암모늄 포스페이트 및 니트릴로트리스(메틸렌 포스포닉산) 암모늄염을 포함한다.
