Prof. Guoxing Sun
Institute of Applied Physics and Materials Engineering, University of Macau, ChinaSpeech Title: Application of Nano-Foam Concrete in Prefabricated Products and Cast-In-Place Projects
Abstract: The speaker will use two examples of industrialized technology inventions to describe how to effectively combine and apply the two different disciplines of chemistry and civil engineering to the research and development of various composite materials, and talk about the stories of commercializing the research products. (1) Use cement as raw material to produce nanoparticles (size <5 nm), and use them to prepare a series of hydrogels with super elasticity, adsorption and water swelling properties, and develop their applications in engineering, electronics, biological materials, environment and other fields. (2) Low-cost, nanoparticle-stabilized foam that can keep stable for years, which could be used to mix with cement paste to prepare lightweight, high-strength, fire-resistant and thermally insulated foam cement. The product was widely used in fabricated lightweight wall panels for energy-efficient buildings.
Biography: Guoxing Sun is an associate professor at University of Macau. He obtained a bachelor and master degree in chemistry from Beijing Normal University in 2004 and 2009, respectively; and a PhD degree in civil engineering from the Hong Kong University of Science and Technology in 2015. His main research interest is organic/inorganic nanocomposite materials. He was managing 12 research projects (totaling RMB 20 million), leading a research group of 48 PhD students and postdoc fellows. He has published more than 100 SCI papers, such as "Nature Communications", "Materials Horizons" and "Journal of Materials Chemistry A". He has applied for 14 national invention patents (1 authorized), and 2 US invention patents (1 authorized). One invention patent has been transformed into a market product, and the current annual output value is about 30 million RMB. Another invention patent has entered the product pilot test stage, and cooperation intentions have been established with more than ten investment companies and customers.
