Boron nitride (BN) materials are attracting more and more attentions due to theirconstant and wide band gap independent of morphology, superb mechanical properties, very high thermal conductivity and marked chemical inertness. Recently, we have developed novel methods for synthesis of large scale highly pure BN nanotubes and nanosheets. Thinner BN nanotubes with diameter smaller than 10 nm were fabricated successfully. Large scale BN nanosheets were also fabricated by the “chemical blowing method”. Subsequently, boron nitride polymeric composites were fabricated and their thermal, electrical and mechanical properties were evaluated. More than 20-fold thermal conductivity improvement was achieved, and such composites keep good electrical insulation. In addition, in situ mechanical and electrical properties from individual BN nanotubes and nanosheets have been successfully studied under the TEMsusing STM/AFM-TEM special holders.
Yoshio Bando received a Ph.D. degree at Osaka University in 1975 and joined the National Institute for Research in Inorganic Materials (at present National Institute for Materials Science, NIMS) the same year. He is now a Fellow of NIMS and a Chief Operating Officer (COO) of International Center for Materials Nanoarchitectonics (WPI-MANA). From1979 to1981, he has been a visiting scientist at the Arizona State University, USA. He served as Professor of Tsukuba University from 1992 to 2008. He is now Adjunct Professor at Waseda University since 2008. He has received a number of awards including the 3rd Thomson Reuters Research Front Award (2012), the 16th Tsukuba Prize (2005), Academic Awards from Japanese Ceramic Society (1997) and Seto Award from the Japanese Society for Electron Microscopy (1994). He is now an adjunct member of the Science Council of Japan and also a Fellow of The American Ceramic Society. He served as Editor-in-chief of Journal of Electron Microscopy from 2008-2012. He has been selected as ISI Highly Cited Researchers in Materials Science. His current research concentrates on synthesis and property of novel inorganic 1D/2D nanomaterials and their in-situ TEM analysis. He and his group researches on “Discovery of nanothermometer”, “Development of high purity synthesis of BN nanotubes, and “Creation of various kinds of novel inorganic nanotubes/nanowires” were internationally accepted.
