Biography

Dr. Nguyen is a staff polymer scientist of the Applied Research Institute (ARI) at the University of Illinois at Urbana-Champaign. He earned his Ph.D. under the advisement of Prof. Michael E. Mackay in the Department of Materials Science and Engineering and the Department of Chemical and Biomolecular Engineering at the University of Delaware. After his Ph.D., Dr. Nguyen moved to the Oak Ridge National Laboratory (ORNL) as a postdoctoral fellow of the Materials Science and Technology Division. Then he was promoted to R&D staff scientist of the Chemical Sciences Division, ORNL. Dr. Nguyen has worked as a tenured assistant professor of the Hanoi University of Science and Technology before joining ARI.

Research Statement

My group research focuses on valorizing renewable materials in three thrusts: 1) Development of stimuli responsive materials; 2) Sustainable plastics and composites; and 3) Novel carbon materials.

Thrust 1. Development of stimuli responsive materials: We have valorized the unique molecular characteristics of renewable materials to design and synthesize a wide range of thermo-adaptive soft materials. We focus on fundamental research to understand and precisely control structure and functionalities of these novel materials. We use advanced characterization methods such as in-situ neutron/light/X-ray scattering techniques, together with in-situ thermal, mechanical and rheological analyses to discover the fundamentals of macromolecular interactions, structural relaxation, molecular dynamics, morphology, and phase changes. These advanced materials are used for healthcare applications such as thermo-adaptive flexible human motion sensors.

Thrust 2. Sustainable plastics and composites: We have focused on understanding fundamentals of biomass structures and macromolecular functionalization to correlate thermoplastic compatibility with processibility in the melt, particularly for compression molding and additive manufacturing. Our studies aim to address global petroleum-based plastic challenges associated with manufacturing and sustainability. We utilize renewable materials combined with a wide range of flexible polymeric chains to produce materials with superior mechanical performance and excellent manufacturing characteristics. Our research also focuses on fundamental understandings of macromolecular behaviors during processing to enhance materials performance.

Thrust 3. Novel carbon materials: Carbon nanoparticles are highly porous, thermally and electrically conductive that can be used for various applications in electronic devices, battery electrodes, supercapacitors, electromagnetic shields, air and water purification. Our research focuses on the development of novel carbon materials with numerous morphological characteristics. We discover fundamental understandings of macromolecular structures, molecular interactions and assembly of renewable materials to guide the designs of these novel carbon materials. The resulting carbon materials with controllable novel morphologies will be utilized in air filter and water purification to prevent the spread of airborne and waterborne diseases.
