Biography

Tianfu Emei Scholar of Sichuan Province, Permanent Member of the State Key Laboratory of Polymer Materials Engineering

I obtained my Ph.D. in Materials Processing Engineering from the College of Polymer Science and Engineering at Sichuan University in 2017, under the supervision of Professor Guangxian Li. During my Ph.D., I spent a year and a half as a joint-training scholar at the Department of Aerospace and Mechanical Engineering at the University of Notre Dame, USA. Following my doctoral studies, I joined the Department of Materials Science and Engineering at Southern University of Science and Technology (SUSTech) as a postdoctoral researcher, working with Professor Chuanfei Guo. In December 2019, I was appointed as a Research Assistant Professor in the department, and by the end of 2020, I joined the College of Polymer Science at Sichuan University through a talent recruitment program.


My research primarily focuses on the long-term serviceability and stability of polymer-based flexible electronic materials and devices under complex environments and operating conditions. Specifically, I explore:

1. High-performance, integrated flexible electronic devices designed for extreme operating conditions, and their long-term service stability.

2. Failure diagnostics, life monitoring, and performance evaluation of functional polymer dielectric materials under new service environments.


To date, I have published over 30 SCI-indexed papers. As the first or corresponding author, I have contributed to renowned international journals such as Nature Communications, ACS Nano, and Advanced Functional Materials. Two of my papers have been selected as ESI Highly Cited Papers (Hot Papers). My work has received over 3,000 citations on Google Scholar, with an H-index of 21. Additionally, I hold 10 Chinese invention patent applications, of which 3 have been granted.


I have led three national-level projects, including a subproject of the National Key Research and Development Program, a General Project of the National Natural Science Foundation of China (NSFC), and a Youth Foundation project. Additionally, I have co-led a subproject of a China-Netherlands International Cooperation project. At the provincial level, I have secured three projects, including the Youth Talent Program of Sichuan Province's "Tianfu Emei Plan," a General Project from the Sichuan Natural Science Foundation, and the Outstanding Young Talents Program of the State Key Laboratory of Polymer Materials Engineering.


In terms of teaching, I deliver core undergraduate courses such as "Fundamentals of Polymer Material Processing" and elective courses like "Principles of Reactive Processing" at the College of Polymer Science. I have supervised undergraduates who have gone on to pursue further studies at institutions like the National University of Singapore, Fudan University, and Sichuan University.


I plan to recruit 1-2 PhD students, 2 master's students, and 3-4 undergraduate students each year. I welcome motivated individuals with a passion for sustainable polymer materials and flexible electronics to join our team!


Research Interests

n Advanced Polymer Materials for High-Power and Extreme Environment Applications. This research foucs on the functional demands of new energy electric vehicles and high-frequency, high-speed electronic information systems. A key aspect of the study is to thoroughly investigate the structure-property relationships and performance degradation mechanisms of typical dielectric functional polymers and composites. The research aims to develop advanced polymer materials with outstanding dielectric properties to perform reliably under extreme conditions, including high-power applications and micro-scale environments, ensuring long-term stability and functionality.

n High-Sensitivity Polymers for Flexible and Wearable Sensing Technologies. This research targets the rapidly growing field of flexible and wearable electronics. The goal is to develop high-sensitivity polymer-based sensing materials that can meet the demands of applications such as health monitoring and tactile sensing in intelligent robotics. By adopting an "integrated processing" approach, the research seeks to create sensors capable of maintaining stable performance over extended periods, even in complex mechanical environments. This would enable these devices to function reliably under varying forces and conditions, making them ideal for real-world applications in wearable technology and robotics.
