Professor You Zhengwei’s research teamfrom College of Materials Science and Engineering developed a new type based on Diels - Alder concerted reaction can be remodeling, biodegradable and dynamic crosslinking elastic polymer, and then through the nanocomposite, constructed the conductive elastomer with good toughness and stretchability, its 3D printing is convenient customizable wearable electronic devices, especially through 3D printing can achieve efficient recycling and synchronous processing recycle directly, to solve the increasingly serious problem of electronic waste provides new material new ideas
The related result was published on Advanced Functional Materials, under the title of “Degradable and Fully Recyclable Dynamic Thermoset Elastomer for 3D-Printed Wearable Electronics”.The doctoral students Guo Yifan and Chen Shuo are the co-first authors, Prof. You Zhengwei the corresponding author.
Design and properties of the PFB elastomer. A) Molecular structure of the PFB with dynamic covalent bond by DA reaction. B) 1H NMR spectrum of precursor PBSF‐FA (CDCl3). C) Schematic for thermoreversible cross‐linking of the PFB elastomer. D) Storage modulus and loss modulus of the PFB versus temperature by rheology test. E) The 3DP of the PFB elastomer
