報告摘要：Combiningfunctional nanoparticles with polymers can create advanced polymernanocomposites, which are recently arousing considerable interest in the fieldof energy storage and conversion. For the power energy storage application indielectric capacitors, we have proposed a concept of “local alignment ofconducting nanoparticles” to develop giant-permittivity polymer composites withlow losses. Further, near-percolated-networks of reduced graphene oxide wereexplored in a soft polymer media to achieve a large permittivity variation withmechanical deformation. The resultant materials show a giant electrostrictivecoefficient and thus can be used in energy harvester to efficiently convertmechanical energy into electricity. In addition, we have also developed polymercomposite fibers to convert thermal energy into mechanical one based on theconcept of shape-memory twisted fiber. Our polymer fibers doped by grapheneoxide exhibit an ever record mechanical energy density, showing a great promisefor the use inminiaturized and strong torsional actuators.
