Keynote Speakers
The information about the Keynote Speakers of ICCHEM2017 is as follows, which will be updated regularly.
Dr. Tingkai Zhao, Professor
School of Materials Science and Engineering, Northwestern Polytechnical University, China

Biography: Dr. Tingkai Zhao has accomplished his doctoral degree in Materials Science from Xi’an Jiaotong University (XJTU) and is currently working as a full professor in School of Materials Science and Engineering of Northwestern Polytechnical University (NPU), China. As the vice-director of Shaanxi Engineering Laboratory for Graphene New Carbon Materials & Applications, his researcher topics are: the synthesis of graphene, carbon nanotubes (single-wall, multi-wall CNTs and amorphous CNTs), flexible graphite, 2D nanomaterials, the growth mechanism, and applications of carbon nanomaterials in composites, energy conversion (solar cell, supercapacitor and Li-ion batteries), smart device and biosensors. In addition, he has published 2 books, 10 patents and more than 100 academic articles on SCI journals. He was also awarded the first prize of the science and technology of Shaanxi province (2013).

Topic: Synthesis of Sandwich Microstructured Expanded Graphite/barium Ferrite Connected with Carbon Nanotube Composite and its Electromagnetic Wave Absorbing Properties

Abstract: The pursuing aim of high reflection loss and broad frequency bandwidth for electromagnetic wave (EMW) absorbing materials is a long-term task and under a close scrutiny. To construct rational microstructures for the absorber have significant impacts on increasing reflection loss and broadening frequency bandwidth. Herein, we presented a sandwich microstructured expand graphite(EG)/BaFe12O19(BF) nanocomposite successfully prepared by in-situ sol-gel auto- combustion method. The experimental results showed that EG/BF nanocomposite has better EMW absorbing performance than pure EG and BF, the sandwich microstructured EG/BF connected with carbon nanotubes (CNTs) could further improve the electromagnetic performance effectively. The obtained CNT/EG/BF nanocomposite exhibited a saturation magnetization of 26.5 emu•g-1 at room temperature and an excellent EMW absorbing performance. The maximum reflection loss of the sandwich microstructured CNT/EG/BF composites with a thickness of 1 mm was up to -45.8 dB and the frequency bandwidth below -10 dB could reach to 4.2 GHz within the frequency range of 2-18 GHz. The research results indicated that the prepared nanocomposite showed great potential as a new type of microwave absorbing material.
