발표 주제 :
탄소 하이브리드 소재를 이용한 고주파 광대역 영역에서의 전자파 차폐 결과 및 응용
본 연구는 다양한 형태의 탄소 섬유 부직포 기반 전자파 차폐 효과를 연구한 결과이다. 전자파 차폐 측정은 광대역 고주파 구간(1 ~ 40GHz)에서 실시하였다. 두께 0.5mm 정도의 탄소 섬유 부직포막 자체의 전자파 차폐효과는 40dB 정도에 달하였으며, 전자파 차폐효과를 향상시키기 위하여 은 나노 코팅 등 다양한 표면처리를 한 결과를 소개하고 있다.
특히, 수소플라즈마로 탄소섬유 표면을 처리한 결과 전기 전도도와 전자파 차폐효과가 크게 향상됨을 알 수 있었다. 탄소섬유에 은 나노 코팅을 한 부직포의 결과에 비하여 수소플라즈마로 탄소섬유의 표면을 처리한 부직포의 전기 전도도는 우수하지 않았으나 전자파 차폐효과는 크게 향상되었다.
또한, 탄소 마이크로 코일로 탄소섬유와 하이브리드 시켰을 경우에도 전자파 차폐효과가 크게 향상됨을 확인할 수 있었다. 그 밖에 다양한 형태의 탄소 섬유기반 전자파 차폐효과 결과와 그 원인에 대하여 발표하고 토의하고자 한다.
n Presenter Biography
Prof. Sung-Hoon Kim is a renowned chemist and materials engineer who has largely influenced his field and directly aided in the development of new chemical synthesis methods and novel nanomaterials. Dr. Kim received a Ph.D. in Chemistry in 1993 from Seoul National University in South Korea. Additionally, Dr. Kim went on to earn another Ph.D. in Advanced Electronics & Optical Science in 2005 from Osaka University in Japan. From 1988 to 1998, he was a Senior Researcher in the New Materials Laboratory of Samsung Advanced Institute of Technology (SAIT). In 1996, he was also an Adjunct Research Associate in the Materials Research Laboratory of The Pennsylvania State University in the United States. Dr. Kim’s experience also includes being a Visiting Scientist in the Division of Advanced Electronics & Optical Science at Osaka University in 2000 and 2001. Subsequently, he worked as a Researcher/Ronpaku Fellow at Osaka University from 2001 to 2005. Dr. Kim was also a Visiting Scientist in the Department of Materials Science & Engineering at North Carolina State University in the United States from 2001 to 2003. Since 1998, Dr. Kim has been a Full Professor in the Department of Engineering in Energy & Applied Chemistry at Silla University in South Korea. He is now the Head of Industry Academy Cooperation Foundation in Silla University.
Dr. Kim’s career is marked by a multitude of pioneering contributions to the field of chemistry and materials, specifically in the areas of diamond thin films and carbon nanomaterials. Dr. Kim has not only developed novel methodologies to produce diamond thin films and carbon materials, but he has revolutionized their application in electronic products. For instance, he took advantage of the lubrication properties of diamond-like carbon (DLC) films to improve VCR heads. DLC components behave as lubricant components that protect the VCR film. Dr. Kim patented this astounding application of diamond-like films in Korea, Japan, and the U.S. The electronics giant Samsung incorporated his diamond-like film technology to its Samsung VCR Head, which became the commercially successful Samsung Diamond Head VCR.
