窒化ホウ素ナノチューブ（ＢＮＮＴ）およびＢＮＮＴポリマー複合体で製作されたエネルギー変換材料

摘要

Electroactive actuation characteristics of novel BNNT based materials are described. Several series of BNNT based electroactive materials including BNNT/polyimide composites and BNNT films are prepared. The BNNT based electroactive materials show high piezoelectric coefficients, d13, about 14.80 pm/V as well as high electrostrictive coefficients, M13, 3.21×10−16 pm2N2. The BNNT based electroactive materials will be used for novel electromechanical energy conversion devices.
