ENERGY CONVERSION MATERIALS FABRICATED WITH BORON NITRIDE NANOTUBES (BNNTS) AND BNNT POLYMER COMPOSITES

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, d 13 , about 14.80 pm/V as well as high electrostrictive coefficients, M 13 , 3.21x1O-16 pm2/V2. The BNNT based electroactive materials will be used for novel electromechanical energy conversion devices.
