報告摘要：Combining functional nanoparticles with polymers can create advanced polymer nanocomposites, which are recently arousing considerable interest in the field of energy storage and conversion. For the power energy storage application in dielectric capacitors, we have proposed a concept of “l(fā)ocal alignment of conducting nanoparticles” to develop giant-permittivity polymer composites with low losses. Further, near-percolated-networks of reduced graphene oxide were explored in a soft polymer media to achieve a large permittivity variation with mechanical deformation. The resultant materials show a giant electrostrictive coefficient and thus can be used in energy harvester to efficiently convert mechanical energy into electricity. In addition, we have also developed polymer composite fibers to convert thermal energy into mechanical one based on the concept of shape-memory twisted fiber. Our polymer fibers doped by graphene oxide exhibit an ever record mechanical energy density, showing a great promise for the use inminiaturized and strong torsional actuators.
