PhD student Zhen Sang’s research was recently accepted to Chemical Engineering Journal!
The article, titled “Dynamic Polymer Network Conductive Nanocomposites: Low Percolation Threshold and Joule-heating-induced Network Plasticity“, is now available to read online. In this work, we report a novel nanocomposite based on Diels-Alder polymer (DAP) dynamic networks. These nanocomposites showed an extremely low percolation threshold at 0.04 wt% filler loading as well as the ability of permanent shape reconfiguration by Joule-heating. Reprogramming directions and time sequences in material motions can facilitate implementations of these actuation systems for applications requiring complex reprogrammable shape manipulations.
PhD candidate Aliaksei Aliakseyeu’s research was recently accepted to Polymer Chemistry!
The article, titled “Nonionic star polymers with upper critical solution temperature in aqueous solutions“, is now available to read online. In this article, novel upper critical solution temperature (UCST) star poly(2-ureido methacrylates) synthesized via ARGET ATRP technique showed DMSO-controlled UCST behavior and enhanced trapping abilities of model drug molecules.
Congratulations, Aliaksei!
Graphic summary of the new publication in Polymer Chemistry
Kartik Kumar Rajagopalan was one of six finalists selected for the 2022 Eastman Chemical Student Award! He will be giving an oral presentation at ACS Fall 2022 in the Eastman Chemical Student Award symposium over his submitted paper, entitled “Infrared Spectroscopy Study of Polymer Gelation Mechanism in Inorganic Salt Hydrates”.
The award is sponsored by Eastman Chemical Company, and the competition is organized by the PMSE division of ACS. The purpose of this award is to “recognize research excellence by a graduate student in applied polymer science”.

Kartik, Parvin, and Xiuzhu wrote a perspective that was recently published in Journal of Materials Chemistry A!
The article, titled “Polymers in Molten Inorganic Salt Hydrates Phase Change Materials: Solubility and Gelation“, provides a unique perspective on the role of molten inorganic salt hydrates as polymer solvents. It also highlights the application of polymer gels formed in these materials as shape stabilizing matrices for thermal energy storage. It is now available to read online.
