Short Biography

Graduated from the University of Sydney with PhD in Mechanical Engineering in 1991, Prof. Kim has more than 30 years of faculty career with the Australian National University (ANU), the Hong Kong University of Science and Technology (HKUST) and the University of New South Wales (UNSW) before joining the Khalifa University of Science & Technology in 2023. Kim served as Associate Dean of Engineering (Research and Graduate Studies, 2007-11), Director of Finetex-HKUST R & D Center (2008-20) and Director of Advanced Engineering Materials Facilities (2015-20) while at HKUST. Kim was the Editor of Composites Part A (2012-23) and is currently Associate Editor of Aerospace Science & Technology and Energy Materials & Devices, apart from sitting in the editorial/advisory boards of 12 refereed journals in advanced materials, including Nanoscale Horizons, Energy Storage Materials, and Nano Materials Science. Kim was the President of the Asian-Australasian Association for Composite Materials (2009-10). He has been honored with many awards, including the Tan Chin Tuan Exchange Fellowship, numerous Best Paper Awards from international conferences together with graduate students, HKUST President Cup Silver Medal, multiple Best Reviewer Awards, and the Life-long Achievement Award.

As an internationally renowned scholar, Prof. Kim is one of the leading authorities in the field of composites, nanocomposites and nanostructured energy storage materials. He has pioneered in the development of multifunctional composites reinforced with 2D and nanocarbon materials for polymer dielectrics, EMI shielding, flexible electronics, sensors, cooling aerogels, and emerging rechargeable batteries/supercapacitors. In recognition of his scholarly achievements and outstanding contributions to professional societies, Kim has been elected as Fellows of prestigious academy and learned societies, including the Hong Kong Academy of Engineering Sciences, the Royal Aeronautical Society, the Royal Society of Chemistry and the Hong Kong Institution of Engineers. The 2023 Stanford University’s Top 2% Scientists List identified him as the top 0.05% most influential scientist in the subfield of Materials in both career total and single year. Kim has been named the Highly Cited Researcher by Clarivate Analytics.

Abstract

The foundation of technology is the understanding of material systems and specific material properties are required for differing applications. In particular, nanoscale 2D materials, like graphene, boron nitride (BN) and MXene, have been the forefront of developing new material systems and devices for emerging applications. This talk focuses on developing thermal management nanocomposites made from these 2D materials. We cultivate the concept of multiscale design and rational assembly approaches [1] to exploite their useful transport properties to obtain optimized architectures with multifunctinal capabilities [2] depending on desired end applications. They include (i) thermally conductive micro-sandwish composites with high energy densities for heat dissipation [3]; (ii) thermally insulating, solar-reflective anisotropic cooling aerogel panels containing inplane aligned pores [4,5] and (iii) biomimicking composite aerogels containing hierarchical porosity for solar-powered water evaporation [6]. The unique and novel properties of these exemplary nanocomposites serve as a testament to the growing popularity and great potential of 2D materials that will lead future development of nanoscience and nanotechnology.
