In 2011, WHO (World Health Organization) reported that electromagnetic waves via cellular phone and other usages can possibly be carcinogenic to human brain [1]. Metallic electromagnetic wave shielding materials have been often used in the past due to their high reflection loss. However, high price of the metals and need of high absorption loss properties required alternative electromagnetic shielding/absorbing materials including nano materials (e.g., carbon nanotube) added epoxy materials. Recently, carbon nanotube added materials having high electromagnetic wave shielding/absorbing characteristics were developed by a number of researchers and their capabilities were evaluated [see e.g., 2,3]. The present paper reviews recent works aimed to develop interior wall board systems with carbon nanotube added materials for shielding/absorbing harmful electromagnetic waves. Details of the summary of the review will be presented.
