| 英文摘要 | Strong flexible polymer/graphene composite films with ideal electromagnetic interference (EMI) shielding are fabricated through constructing a sandwich structure consisting of polyester non-woven fabric as reinforcing interlayer and thermoplastic polyurethane (TPU) composite with high graphene loading as conductive coating layer. The engineered sandwich film (defined as TPU/G film) with graphene ;loading of similar to 20 wt% and total coating thickness of similar to 50 mu m not only possesses excellent mechanical flexibility and strong strength, but also exhibits qualified bandwidth of shielding effectiveness (SE) >= 20 dB as wide as similar to 49.1 GHz in a broadband frequency range of 5.4-59.6 GHz. Moreover, saw-tooth folding of the flexible TPU/G films could efficiently enhance the shielding performance, and more conductive folded film with smaller included angle plus longer side would result in much greater SE enhancement along with reduced EM reflection. This finding also realizes the convenient performance regulation of the folded TPU/G films through a simple mechanical deformation, showing promise for tunable EMI shielding. (C) 2016 Elsevier Ltd.
