TL;DR: A simple and versatile gel permeation chromatography (GPC) methodology for molecular weight (MW) characterization of PILs with a variety of anions is developed.
Journal ArticleDOI
Biologically Derived Soft Conducting Hydrogels Using Heparin-Doped Polymer Networks
Hangjun Ding,Mingjiang Zhong,Young Jo Kim,Pitirat Pholpabu,Aditya Balasubramanian,Chin Ming Hui,Hongkun He,Huai Yang,Krzysztof Matyjaszewski,Christopher J. Bettinger +9 more
TL;DR: The use of biologically derived heparins as scaffold materials for fabricating networks with hybrid electronic/ionic conductivity and ultracompliant mechanical properties are described, suggesting that heparin/polyaniline hydrogel networks exhibit suitable physical properties as an electronically active biointerface material that can match the mechanical properties of soft tissues composed of excitable cells.
Journal ArticleDOI
Reversible CO2 capture with porous polymers using the humidity swing
Hongkun He,Wenwen Li,Mingjiang Zhong,Dominik Konkolewicz,Dingcai Wu,Karin Yaccato,Tim Rappold,Glenn Sugar,Nathaniel E. David,Krzysztof Matyjaszewski +9 more
TL;DR: In this paper, a new direction for the design of porous polymeric materials for CO2 air capture has been suggested, which suggests an order of magnitude improvement in the kinetics of the absorption and desorption processes and a significant improvement in swing sizes compared to a commercially available material with similar functional groups.
